ABSTRACT:
A high pressure roller press for interparticle crushing of material including opposed crushing rollers with at least one roller being movable, a gate controlled material feed to the nip of the rollers, means measuring the nip width by measuring the distance between bearings of the rollers, means measuring the nip force by measuring the hydraulic pressure applied to the movable roller to obtain nip force, a comparator receiving signals of nip width and nip force and having an output to maintain a linear relationship between nip width and nip force and controlling the feed to the nip and the nip width to maintain the relationship.
