'''Scraper discharges''' are used for demanding, discharging high-consistency, fibrous slurry tower applications to ensure process reliability, high efficiency, and low operating costs.

The Discharge Scraper operates in connection with a medium consistency tower bottom discharge pump. The scraper works over the complete bottom area and directs the pulp to the suction opening of the discharge pump. The homogenized bottom area pulp consistency enables a uniform discharge and prevents channeling in the tower.

When combined with an MC pump, the Discharge Scraper produces a stable feed flow to downstream processes such as brownstock washing, oxygen delignification, and the bleaching stages.

==Horizontal Scraper Discharge==
The horizontal scraper discharge centrifuge is a piece of solid-liquid separation equipment with continuous operation and discontinuous discharge. The horizontal scraper discharge centrifuge has a fixed filter bed. Under the action of centrifugal force, the horizontal scraper discharge centrifuge can periodically feed, separate (dehydrate), wash and scraper, and is automatically controlled by the combination of hydraulic and electric.

The horizontal scraper discharge centrifuge is utilized for situations in which solid particle size is greater than 10μm, the mass fraction of solid-phase is 25%～60% and the viscosity of liquid-phase is less than 0.01Pa.s.

===Working principle of horizontal scraper discharge centrifuge===
After the basket rotating at full speed, the feed valve shall automatically open and the suspension shall enter into the basket through feed pipe. With the help of harrow teeth, the solid-phase medium shall be uniformly distributed inside filter basket, while the liquid-phase medium shall be thrown out through the filter screen and filtration pore on basket wall. With the increase of cake thickness, the harrow teeth rotate relatively. When the harrow teeth rotate to a certain point (the materials layer reaches the allowable maximum thickness), the limit switch is touched and the relay is cut off so that the feed valve shall close to stop feeding. At the same time, the washing valve automatically opens and the washing liquid sprays on the filter cake. After the cake is fully washed, washing valve closes. The centrifuge shall dewater and dry materials. Then the scraper elevates to scraper vertically. The materials which are scrapered down shall be discharged from the centrifuge under the action of gravity. When the materials inside the basket are emptied, the filter screen shall regenerate. After finishing a cycle, the centrifuge shall automatically enter next cycle. For most materials, the left filter cake layer does not need to be washed after scratching at a time, but usually needs to be washed at intervals of 4 ~ 8h.

===Types and operation modes of horizontal scraper discharge centrifuge===
The horizontal scraper discharge centrifuge can be grouped into common filtration type and siphon filtration type. The horizontal siphon scraper discharge centrifuge has such features as strong separating capacity and easily adjustable filtration velocity, is suitable for the services in which the filter cake is difficult to dewater, the high requirements for the cake washing and for the ultimate moisture content of cake are required.

The horizontal scraper discharge centrifuge control system usually adopts the combination of hydraulic and electrical control to achieve higher automation.

===Discharge mechanism and damping device of horizontal scraper discharge centrifuge===
The discharge mechanism of horizontal scraper discharge centrifuge is related to the characteristics of filter cake. For the dense filter cake, the narrow scraper shall be selected. While for the most of the loose cakes, the wide scraper generally is adopted. The feed method of scraper can be classified into elevating and rotating scraper. The discharge method includes chute discharge and scroll conveyor discharge. The materials of blade usually are galvanized iron bronze, 1Cr18Ni9Ni, 2Cr13 or spring steel, etc.

The centrifuge vibrates obviously because of the residual unbalance of basket, the interference and uneven material distribution which are caused during feeding and scraper discharging, and the distorted structure of centrifuge cantilever and so on, the damping device is needed for horizontal scraper discharge centrifuge. Most of damping devices adopt rubber or metal spring vibration isolator. The natural frequency of vibration system is 1/4～1/3 of gyro frequency of the machine.

===Horizontal siphon scraper discharge centrifuge===
The horizontal siphon scraper discharge centrifuge is a kind of scraper discharge centrifuge whose driving force of separation includes both centrifugal force and siphon suction force. Compared with the common horizontal scraper discharge centrifuge, the horizontal siphon scraper centrifuge has higher production capacity and better separation effect. The siphon scraper centrifuge not only can be used for the separation and dehydration of re-alkali, caustic soda and starch, but especially suitable for separating liquid-solid two-phases with small solid particles in suspension, slower filtration velocity and higher requirements for washing cake.

Compared with the common horizontal centrifuge, the siphon scraper centrifuge has following characteristics.

① Compared with the horizontal scraper discharge centrifuge with the same specification, the production capacity increases by 40%～60% and the moisture content of filter cake is lower.

② The filtration velocity can be adjusted by changing the position of siphon suction inlet, so as to get different filtration rate for feeding, separating, washing and dewatering cake and keep the centrifuge operation under the best condition. Horizontal siphon scraper discharge centrifuge has characteristics of smooth operation and less vibration and noise.

③ This equipment not only can be automatically controlled by the combination of hydraulic and electrical control, but also has characteristics of accurate and reliable program operation, and convenient adjustment and maintenance.

===Type selections of horizontal scraper discharge centrifuge===
① The horizontal siphon scraper discharge centrifuge is suitable for the materials in which the mass fraction of solid phase in suspension is 25%～60%, or the materials with average solid particle size of 15μm and the viscosity of 10Pa.s. For flammable, explosive and poisonous materials, the closed explosion-proof scraper centrifuge should be adopted.

② When the filtration rate of the filtered material is low and the requirement for cake washing and cake moisture content is high, or in order to improve production capacity, siphon scraper centrifuge should be selected.

③ When the horizontal scraper discharge centrifuge is selected, the steady feed quantity and solid-phase concentration in process system should be ensured. Otherwise the larger vibration and noise shall occur to influence the using effect of centrifuge or cause unsafe factors.

④ The horizontal scraper discharge centrifuge has a certain damage to the dewatered solid particles, is not suitable for the solid particles which are not allowed to be broken.

⑤ For the situations in which the residue is easy to harden after dehydration or the filter medium is easy to be blocked while separating the solid-phase, the horizontal scraper discharge centrifuge should not be selected.

⑥ The centrifuge with the specific specifications can be chosen based on the previous experience. A suitable centrifuge generally shall be determined by experiment.

[[File:Aerator_Pads.jpg|thumb|200px|right|Aerator Pad]]
'''Aerator Pads''' will help with uniform flow and discharge of dry bulk materials through aeration and [[Hoppers|hopper]] wall vibration. It prevents bridging, rat holing and compacting in storage [[silos]], dust collectors, weigh [[bins]] and [[IBC's]]. Aeration pads are simple to use, low cost flow aids. Pads introduce low volume air into the powder through a non-clogging diffuser.

==Principle of Operations==
Aerator Pads operates by continuously introducing air into the body of the dry powder. When a powder is first conveyed into a storage vessel it is actually a highly aerated mixture of air and particulate. In this state the mixture flows quite readily. However, as the powder settles the solid particulate and air separate resulting in a decrease in volume and an increase in bulk density. In this deaerated state powders can behave more like a single large solid structure rather than a fluid-like mixture. By replacing the naturally lost air, the air to particulate mixture ratio is held thus maintaining the fluid like characteristic of the aerated powder.

The term '''banana screen''' can be deceiving. If one were to search the internet looking for “banana screen”, inevitably one would stumble on that yellow fruit with that distinctive shape or a screen saver with that name. Or, one could get links to websites of different manufacturers of this processing equipment.

It is that distinctive shape that gave the multi-sloped screen the name “banana”. In industry, the “banana” term is used interchangeably with “multi-sloped”,That European manufacturer later set up their own offices in Australia and I began doing marketing communication work for that company in the mid 90s. Used in wet and dry applications, banana screens are vibratory equipment which use the distinctive shape to process larger volumes of material using a smaller footprint. This is compared to inclined horizontal screens, which as the name implies are horizontal and donʼt have the banana shape. Screens, including banana screens, are used in mining and mineral processing industries. Used in different stages of the process cycle, in either wet or dry applications, the objective of using these equipment is to group together a specific mineral-size fractions, while reducing the the amount of fines carried over with the oversized material.

Improper screening means that there will be a high amount of fines that will remain with the oversized material. This results in high recirculation volumes and greater wear of downstream process equipment. As well, lost production due to downtime is a possibility. The result of proper screening is less crusher wear, less unnecessary recirculation and of course, lower production costs. The points at which screens are used depends on the mineral/ore mined, the nature of the processing plant, the different components of that plant, desired final product and so on. These screens come in a range of sizes and can be built as single or double deck units. They are used more commonly to size ore at one of the stages (primary, secondary, tertiary, quarternary) for further processing. In Australia, banana screens have found a lot use in coal processing. They are widely used for mineral recovery and scalping. Being multislope, they offer higher screening capacity as mentioned earlier. The also are good for recovery in feeds with a very high percentage of near-sized material.

In the coal industry, banana screens are normally used in the second, third or fourth stages of processing plants. To separate material, banana screens use different media. Choice of media, e.g., woven wire, rubber, polyurethane, is guided by the ore/material being processed, the tonnage of throughput and so on.

[[File:Solid State Analyzers.jpg|thumb|right|Solid State Analyzers]]
'''Solid State Analyzer''' designed for non-invasive measurements on powders, pellets, liquids.It is ideal for implementing in the actual process by means of direct reflectance mode or through a window. In physical and bio-optical sensors have seen significant progress during the last decade, and numerous systems are now deployed regularly collecting underwater data in real time. In chemical detectors, however, are severely lagging their counterparts, and marine chemists still rely for the most part on collecting samples and carrying out shipboard or laboratory analyses. Although significant efforts have been made developing several chemical sensors, they are generally complex, not very user-friendly, and limited in their analytical capabilities.

In response to this problem and the proliferation of remote and interactive real-time underwater process studies, this project has been investigating liquid handling and detection technologies for chemical analyzers capable of more rapid, flexible, and complex analyses. Such analyzers will have wide-scale applications including 3-D underwater chemical mapping, determining chemical gradients at the sediment-water interface or around specific micro-environments, locating chemical sources, and studying biogeochemical processes. The overall goal is to significantly decrease the per-sample cost and handling time, to multiply the potential spatial and temporal data coverage, and to reduce errors due to contamination and sample handling. State-of-the-art microelectromechanical system technology provides a unique opportunity for designing general-purpose miniature fluid-handling systems with integrated detectors. This project has thus been working toward developing complete chemical analyzers with valves, pumps, and detectors on pyrex-siliconwafer chips. Silicon-based analyzers are relatively simple to manufacture using existing etching methods developed by the electronics industry, and will therefore be cost-effective in the long run. A major advantage of this system is that chemistries are fully software driven, allowing a much more rapid adaptation of chemistries and flexible experiments. In the last year a second generation modular analyzer was designed and tested on a 2-by-4 centimeter micromachined pyrex-silicon wafer. Unlike similar biomedical analyzers, this system is based on a new valve designed specifically for liquid and capable of operating at full ocean pressures. The system’s lack of moving parts, small size, and ability to be fully computer controlled, may make these analyzers the next generation of useful in situoceanographic analyzers for dissolved constituents

'''Volumetric Feeders''' are universally acclaimed for their unique ability to accurately and reliably feed an extremely broad variety of dry solid ingredients. These innovative and technologically superior designs provide a high degree of versatile volumetric metering performance. The quality of construction and durability of these volumetric feeders is unsurpassed; their maintenance requirements are the lowest in the industry. A true volumetric feeder encompasses a positive method of measuring a specific volume of product and a means to effectively discharge that material, generally over a variable range. With an auger type volumetric feeder, the auger is the means used to measure volume, discharging the “measured” volume of material with each revolution, as it typically rotates through a discharge spout. Consequently, the viability of any auger type volumetric feeder is dependent upon how uniformly and consistently the feed auger is filled with product, and how reliably this is accomplished. Even in view of today’s technological accomplishments, the precise and dependable volumetric metering of dry solid ingredients remains far more of an art than a science; unquestionably, specific expertise and experience plays the most crucial role. And since it is also a well-established fact that no single approach to dry solids volumetric metering has been able to solve all materials-handling variables, Acrison has designed and manufactures a number of different auger type volumetric feeder models in order to successfully handle the incredible number and diversity of dry solid materials. Each of these individual volumetric feeder models possesses specific functionality, suitable to handle a range of product characteristics. For example, feeding very free-flowing products such as coffee beans, grass seed or plastic pellets really doesn’t require much mechanical sophistication; however, to accurately and dependably meter sluggish amorphous materials, especially those with adhesive, cohesive and/or pressure sensitive characteristics, is a challenge. Today, dry solid volumetric feeders that range from single auger volumetric feeders to handle the generally easier free-flowing materials, to various type dissimilar speed, multiple auger and agitated flat bottom volumetric feeders for the more difficult-handling products.

The '''Vacuum Feeders''' are commonly used with automation of plastics processes such as plastics extrusion, compounding and resin manufacturing can be accomplished with pneumatic conveying, feeders and related bulk material handling equipment. There handling systems are used for transporting powder and granular bulk materials from rail car unloading to storing and dust collection systems, conveying to feeding, blending, scaling, and sifting operations and integration with drying systems.

Gravimetric and volumetric feeders and pneumatic conveying components are in the flow of plastics, from resin manufacturing, to precision compounding, high speed compounding, and end product extrusion. These feeders control the flow of the granular base polymer and a filler, carbon black, slip agent and other additives to a pelletizer. Two grades of the resin are fed by smart flow meters with rotary valves. The filler is proportioned by a high-rate modular single screw loss-in-weight feeder, while the difficult to handle carbon black requires twin screw feeding. Slip agent and other additives use lower capacity feeders. Controller handles up to 15 feeders. Feeders help make a wide range of additives used in plastics, too. Twin screw loss-in-weight feeder doses ingredients to a classifier to produce various grades of the pigment.

With the higher throughput rates made possible with today's high-speed extruders, Continuous Gravimetric Blender System allows four to six ingredient stations with Premier Pneumatics conveying receivers easily grouped around the extruder inlet. Ingredients are continuously feed in sychronized, weighed proportion, whether pellet, granule or powder. Resin and other high rate components such as filler merge with other ingredients at the throat, eliminating the need for mixing. Liquid loss-in-weight feeders can introduce liquid additives downstream.

End product extrusion: In critical end product applications like wire and cable coating, quality hinges on reliably consistent blend accuracy. By combining all-digital weighing technology, microprocessor control, and the broadest range of material handing capability, feeding system continuously proportions pellets, powders and granules at the extruder, eliminating the need for mixing and assuring the highest possible end product consistency.

Fiber and Filaments: Feeders are the key to color. In carpet filamentmanufacture, even the subtlest variation is unacceptable. With feeding system, processors can handle nearly any ingredient online, without risk of material segregation - a major cause of transient color shift. The stability of all digital system, from weight measurement to feeder control, assures blend consistency not only from moment to moment, but from day to day, week to week, month to month.

'''Twin motor feeders''' convey product by utilizing two counter rotating rotary electric drives. Because the motors counter rotate, lateral forces are canceled out and linear forces are combined, providing quiet and positive conveyance action. This method requires no belts, crank arms, rocker arms or leaf springs which leads to minimum downtime. The synchronized motors provide a semi-balanced design, eliminating uncontrolled bouncing during shutdown. Twin motor feeders' heavy-duty construction and durable components are ideal for many industries and applications.

==Applications==
*Dry bulk material handling
*Metal recycling
*Glass recycling
*Waste recycling
*Mining
*Aggregates
*Wood

==Benefits==
*Heavy-duty construction
*Capacities ranging from 60-3,500 TPH
*Base mounted or suspension mounted isolation
*Customized design
*Low maintenance
*Quiet operation

Twin motor drive feeder and conveyor units are ideal for high capacity feeding and conveying applications where the throughput rate is fixed or infrequent adjustment is required. They are used in many industries, such as, steel making, mining, quarrying, foundries, food processing and chemical industry for the feeding and transfer of bulk materials. Unlike other systems, they are simple to install and do not require skilled tuning on site. Although the maximum single unit length is 6m, multiple units can be mounted in series with minimal or no height loss to achieve greater conveying lengths.

The main construction consists of a weld fabricated conveying trough, which can be supplied as a trapezoidal, rectangular or tubular assembly, and drive assembly onto which the vibrator motors are mounted. The drives and drive assembly can be mounted below or above the trough. The trough and associated structure are normally manufactured from carbon steel, stainless steel or a combination of both. These materials are adequate for the majority of applications, but the conveying troughs can also be manufactured from other materials, such as abrasion resistant steel, polypropylene, etc. Also, liners and coatings can be incorporated into the hough to help eliminate or minimize various problems, such as: expendable liners for highly abrasive applications; flexible liners for light products that have a tendency to adhere or compact; energy absorption liners like laminated steel and rubber, polypropylene, rubber and polyurethane which minimize noise generation caused by the impacting of the product on the trough during conveying.

Tubular feeders and conveyors are particularly suitable for applications where dust emissions, atmospheric pollution or product contamination are to be prevented. The conveying tubes are crevice free and can be fitted with either bolted or quick release dust tight end plates. Bolted or quick release dust tight covers can also be fitted to trapezoidal or rectangular section troughs on which both the inlet cover and the outlet of the conveying trough can be fitted with either discharge spigots or bolting flanges for flexible sleeves. All the equipment can be manufactured in accordance with the hygienic and legislative requirements of the food and pharmaceutical industries. A range of equipment finishes are available for both product contact and non contact surfaces which include spraying, powder coating, polishing and bead blasting.

A '''Trough Feeder''' is ideal for use as a collecting or distributing [[Conveyors]]. A typical application is the flour collector in a grain mill.
Through Feeder is a feeder that is made of carved stone, wood, or metal construction and is used to hold food for animals (as in a stable). Mangers are mostly used in livestock raising. They are also used to feed wild animals, e.g., in nature reserves. The word comes from the French manger (meaning "to eat"), from Latin manducare (meaning "to chew").
Feed troughs are commonly used for feeding large farm animals. Essentially a community eating area, a simple trough can be built out of an old plastic barrel. Not only is it durable and capable of standing up to the test of time as well as the interaction with large animals such as cattle and horses, but a plastic feed trough is transportable so you can move it as you need, such as for switching between corrals or fenced in areas.

==Applications==
* Horizontal or inclined material conveying, distribution, collection, mixing and discharge
* For floury and mealy, fine- and coarse-grained materials
* Application in grain mills and feed manufacturing plants, malthouses, bulk storage systems (for cereal grains, oil seeds and derivatives), food processing facilities, fertilizer factories, and in chemical and related industries
