Gyratory Mantles and Concaves. Gyratory mantle and concave design is pivotal to downstream process efficiency. Due to inconsistent feed size, fines ratio, clay content, moisture and throughput rates, gyratory crushers have inherent problems of poor wear predictability of both mantle and concaves and excessive wear in the lower chamber.

The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to 1.5 m (for the largest equipment).. This crusher can handle products with a Mohs hardness that is not necessarily less than 5. – As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.

A gyratory crusher uses a mantle that gyrates (rotates) within a cone shaped inner surface lined with wear resisting plates often called concaves. As the mantle gyrates within the crushing chamber, progressively approaching, and receding from, each element of the cone shaped inner surface, it creates compressive force, which fractures the ...
