Cement grinding Vertical roller mills versus ball mills. The grinding process in ball mills and vertical roller mills differ fundamentally In a ball mill the comminution takes place by impact and attrition The comminution in the vertical roller mill takes place by exposing a bed of material to a pressure sufficiently high to cause fracture of ...
High pressure grinding rolls. 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 ...
Noncontact roller measuring device In the cement and mineral industry roller mills are used for fine grinding of the raw materials. During the milling process the rollers are subject to high wear, which strongly reduces the quality of milling at the edges of the rollers.
