These rolls draw the feed material into the gap between them, where it is ground under high pressure. A hydro- pneumatic system generates the required grinding pressure of up to 250 MPa. The grinding process produces compacted cakes containing a high proportion of fines, as well as coarser particles with cracks in them.

The pressure is limited only by the size of the pump, not by atmospheric pressure. 30-40 psi is typical of an Oberlin filter. This is about three to four times more pressure than gravity or vacuum filters can develop. The time it takes to reach 10 psi is much less than the time to reach 30-35 psi in many applications.
