ABSTRACT:
An improved vertical roller mill for comminuting solid materials which includes a horizontal grinding table and cooperating grinding rollers and an improved apparatus for exerting a downward force on the grinding roller. This apparatus includes an external hydraulic piston-cylinder force exerting apparatus with a pair of link members external to the mill with a first link member in tension and a second link member in compression. The compression link is pivotally connected to the mill body and the force exerting apparatus and the tension link is pivotally connected to the force exerting means so that when the cylinder of the piston cylinder means moves down, the linkage mechanism results in a downward force on the grinding roll.
