In double-toggle jaw crushers, the pitman is mounted on fixed non-eccentric shaft that situated at the top of the crusher. There are two toggle plates, one on the left and one on the right, are linked to the pitman that is hinged to the driven camshaft. The toggle plate on the left is linked to the jaw-supporting block, while the one on the

A jaw crusher in which the motion of the eccentric shaft is transmitted through the pitman to a toggle joint, formed by two toggle plates hinged together, 

Additionally, our double toggle jaw crushers do not require massive and costly foundations as do other jaw crusher designs. That's because our jaws are designed 

This paper conducts a comprehensive study on the optimization design for crushing mechanism of double toggle jaw crusher. The optimization aim is to reduce 

Abstract. The purpose of this article is to obtain a comprehensive mathematical description of the kinematics of a double-toggle jaw crusher.

Double Toggle Grease Jaw Crusher. M EWAR'S Double Toggle Grease Lubricated Jaw Crusher is primary equipment for production without large generation of fines.
