Four Roller Double Pressing Briquette Press

Four Rollers Double Pressing Briquette Press can supply higher pressure and high density during production of briquettes; it's mainly used in making briquettes of various materials, including colored and black metallic mine powder: iron scale, iron sludge, precipitator dust, iron concentrate, raw material powder, manganese ore fines, silicomanganese alloy, coal, coal powder, coke powder, slime peat, middle coal, lignite charcoal powder, fireproof material, desulphurization gypsum, dolomite etc.
This type of briquette press have two larger rollers in a fixed position on the frame, the other two smaller rollers are moveable. As its named implies, it has four rollers and presses twice in the production of briquettes.
In order to ensure good quality and mechanical strength of the final product, special care should be taken to ensure that the granule size fed to the machine is maintained below 3mm, preferably in the range of 30-40% smaller than 1–2 mm, with no more than 10% over 2 mm. The moisture content of the mixture should be kept in the range of 8-10%.
