Size Enlargement Solids Briquetting

Product diameter 2-5 mm capacity 0.001 to 30 kg/s. Tensile strength of the agglomerate 10 to 200 kPa, depending on the binder. 

Need closed circuit operation to achieve uniformity in product size. 

Product diameter 15 to 80 mm capacity 1 to 30 kg/s. Crushing strength of agglomerate 1-10 MPa. 

Constant product volume operating pressure 50 MPa. Power 2 to 50 MJ/Mg. 

Operate either as constant volume machine mechanical tabletter with operating pressure 50 MPa or as constant mechanical tensile strength (constant pressure) machine hydraulic tabletter with operating pressure 150 to 250 MPa. Power 50-60 MJ/Mg.

An alternative approach to size enlargement is agglomeration by compression, or compaction, where the mixture of particulate matter is fed to a compression device which promotes agglomeration due to pressure, as depicted in Figure 2. Either continuous sheets of solid material or solid forms such as briquettes or tablets are produced. Compaction processes range from confined compression devices such as tableting to continuous devices such as roll presses (Chapter 6), briqueting machines.
