This paper sets out to perform a static force analysis of the single toggle jaw crusher mechanism and to obtain the force transmission characteristics of the mechanism. In order to obtain force transmission metrics that are characteristic of the structure of the mechanism, such influences as friction, dead weight, and inertia are considered to be extraneous and neglected.
Jaw Crusher_The Nile Co., Ltd. Jaw Crusher Working Principle The motor drives belt and belt wheel, the eccentric shaft causes the movable jaw to move down and up, forward and backward, the angle between toggle plate and movable jaw becomes bigger when the movable jaw moves up, so that the movable jaw moves toward the fixed jaw, and the materials are pressed, crushed, or cut, as a result, …
The Characteristic of JAW CRUSHERS. SAMYOUNG Single Toggle Crushers are designed with years of experience in manufacturing various types of crushers, and are manufactured with our finest workmanship.
