Working principle. Vertical mills comprise 24 conical rollers which are hydraulically pressed onto a horizontal rotating grinding table. The roller axis is inclined at 15o to the table and, as axes of rollers and table do not intersect in the plane of the table. the relative motion involves both rolling and sliding which enhances comminution.

Vertical roller mills, especially those common for grinding of cement raw materials, typically employ a hydraulicpneumatic system to apply a grinding force to the material bed. During operation, these systems will contain pressurized hydraulic fluid in an isolated branch of the circuit consisting principally of cylinders and accumulators.

Principle Principle of Grinding for these mills are done by Attrition and Compression method. The grinding force are applied through the sets of rollers on to the material bed spread over the rotating grinding table. This causes attrition initially followed by compression from external grinding forces.
