Jaw Crushers

Jaw Crushers
Double Toggle Jaw Crusher

Jaw crushers process medium to hard quarry rock or other materials by compressing it between the fixed jaw and the swing jaw. The swing jaw being the moving part is attached to a rotating eccentric shaft. The fixed jaw is an integral part of the crusher frame. Both jaws are fitted with manganese jaw liners that can be replaced or reversed when worn.

During the crushing operation, the toggle plate which acts as a pivot point for the jawstock, controls movement of the lower part of the swing jaw.

SINGLE TOGGLE JAW CRUSHERS

The single toggle crusher is designed for a high capacity throughput due to the elliptical movement of the swing jaw which also assists in the discharge of the crushed material. As the single toggle crusher will achieve far higher capacities than the double toggle design, they are often used as a primary crusher.

DOUBLE TOGGLE JAW CRUSHERS

Double toggle crushers are the preferred machine for harder and highly abrasive materials with a compressive strength of up to 600 Mpa.

The double toggle is capable of handling extremely hard rock and Ferro materials, but rate of feed and reduction ratio’s are restricted. With the top of the hinged swing jaw almost perpendicular to the crushing chamber, high compression is achieved by the linear stroke of the toggle movement thus minimising wear on the jaw liners.
