Abstract
A crusher comprises a cylindrical body, a lining supported by a portion of the cylindrical body and forming an annular track, the supporting cylindrical body portion having a prismatic interior surface, and at least one roller arranged to roll on the annular track. The lining consists of plates having a concave interior surface shaped to form a rolling surface of the annular track and a flat exterior surface resting on the prismatic interior surface of the supporting cylindrical body portion. This reduces the risk of breakage of the lining plates under the pressure applied thereto by the roller.
