Total load on
the moulding rolls : these loads are generally located between 50 and
7000 kN from the lab press to the largest compactor operating on potash. The
total load equals the specific load in kN/cm linear multiplied by the roll
width in cm.
Capacity :
the smallest units have a capacity of 10-30 kg/h. The largest exceed 100 T/h,
particularly when compacted sheets are produced. Each category of raw material
processed has a limit in terms of unit capacity per press or compactor due
to the raw material characteristics themselves, the design of the press/compactor
(feed system, roller bearing size etc...)
Feed system :
Gravity or screw feeder can be used. Force-feeder can be vertical or horizontal.
Power / torque
installed for roll drive : they vary between 2 and 800 kW. Weights of
presses can therefore vary between 500 kg and more than 100 tonnes.
