	Agglomerators are used to increase the particle size of powders. They are very useful for powders of different particle sizes and/or densities that would otherwise seperate when handled. They are used when minor ingredients, often expensive ingredients, must be uniform throughtout a powder.

	There are two basic types of agglomerators; compaction and noncompaction. The compaction type uses mechanical pressure (and often very high pressures) to "press" the powders together. For these, binders are sometimes not needed to make the particle. Compaction agglomerators are highly specialized, and not addressed here.

	Agglomerators keep the powders mixing while spraying a binding liquid. The binder is sprayed and then dries or sets or cures or otherwise hardens sealing the powders into a single bead. The need to keep the powders well mixed usually works against the idea of agglomeration. Mixers use high shear for mixing. This high shear also breaks particles down rather then agglomerates them.

	Capping beads is a simpler process because the shape of the hole is not as critical. The hole in the cap is critical and should not be too large. The tricky part about capping and riveting beads is how much tubing to use. Too little and you will not be able to set the rivet. If you use too much there will be excess silver that you will not be able to get the silver rivet to lay flat on the cap. Determining the proper length is a trial and error process but it did not take me long to figure it out.		[[File:Batch_agglorometer2.jpg\|thumb\|right\|Batch_agglorometer]]

	~~Capping and riveting beads is a two step process, flaring~~ the ~~tubing and then setting the rivet~~. ~~The press is~~ very ~~good~~ for ~~flaring tubing~~ and ~~I have used up to 1~~/~~2" inch tubing with no problems. The press has an anvil, the bottom piece with the low angle cone (Fig. #2) This cone makes sure~~ that ~~the tubing is aligned with the die~~. ~~The die is the top piece and does all of the work and can flare tubing up to 3/16 outside diameter. Watch the top piece~~ when ~~flaring the tubing and making sure that the ends of the flared tubing are symmetrical~~.		Agglomerators are used to increase the particle size of powders. They are very useful for powders of different particle sizes and/or densities that would otherwise seperate when handled. They are used when minor ingredients, often expensive ingredients, must be uniform throughtout a powder.

	~~==Process==~~		There are two basic types of agglomerators; compaction and noncompaction. The compaction type uses mechanical pressure (and often very high pressures) to "press" the powders together. For these, binders are sometimes not needed to make the particle. Compaction agglomerators are highly specialized, and not addressed here.

	~~1) Cut tubing to proper length about 1/16 for each side~~ of ~~bead in addition to the width~~ of ~~the bead. Be sure to de burr the tubing before riveting. If the tubing splits when riveting it was cut too long. I buy my tubing from Rio grand~~ and ~~Metaliferous~~.		Any system that consists of at least one powder of any size, or mixture of sizes, and a liquid binder are agglomeration candidates.

	~~2) Place tubing between~~ the ~~die~~ and ~~anvil in~~ the ~~press and pull down on~~ the ~~lever until~~ the ~~top die flares the tubing~~. ~~Make sure it flares it enough so that~~ the ~~caps or bead to be riveted will not fall off~~ of the ~~flared end~~.

Ed O'Brien came up with the idea of a gentle mixing within his agglomerator in the 1960s.

	3) Put bead or caps and bead on tubing with the flared end down back in the press. Repeat Step #2. Make sure both ends are flared evenly by placing the smaller end of the rivet pointing up in the press and pulling the lever making it larger.		==Process==

	4) ~~Stop when~~ the ~~tubing starts to get tight. If you keep pressing the bead will chip or break~~.		1) The requested production capacities are normally in the range between 1000 and 4000 kg/hr.

Using small hammers and supporting the bottom of the rivet when pounding on the top seems to set the rivet nicely.		4) The complete process normally consists of two separate mixing processes.
