The movement of the floating roller constitutes the basic principle of a roller press. The extent of the roller movement (roller gap) is a function of the pressing force generated by the hydraulic system in relation to the reaction forces exerted by the material being processed and the preset "zeroposition" of the roller gap.
A high pressure grinding roll, often referred to as HPGRs or roller press, consists out of two rollers with the same dimensions, which are rotating against each other with the same circumferential speed. The special feeding of bulk material through a hopper leads to a material bed between the two rollers.

Re: Cement roller press. You get that by: measuring the flow through the press (M [kg/s]) measuring the gap between the rollers (e [m]) measuring the width of the cake (L [m]) measuring the rotation speed of the press (RPM) measuring the diameter of the press (D [m]) You can then calculate: the angular speed w = RPM/60 [/s] the radius of the ...
