high pressure grinding roll technology for sale

A novel approach for the modelling of high-pressure grinding …

The pressure exerted by the hydraulic system on the floating roll, that allows horizontal movement of the moving roll, largely determines comminution performance. Typically, operating pressures are in the range of 5–10 MPa, but can be as high as 18 MPa. For the largest machines, this translates to forces of up to 25,000 kN (Morley, 2006).
