Abstract

A gyratory type crusher having a crushing head rotatably mounted on an upright eccentric wherein the head gyrates in respect to a cooperating concave and thereby effects a crushing action when material is in the annular crushing chamber which is formed between the head and the concave. The head is rotatably mounted on a rotating eccentric which imparts a gyratory movement to the head relative to the concave. Means are provided for restraining the rotation of the head relative to the concave when the crushing chamber is empty or when the material is initially being introduced into the crushing chamber. The construction of the restrainer is such that the head is permitted to rotate backwards during the crushing operation and which backward rotation is due to the crushing action.
