What’s the Working Principle of Single Toggle Jaw Crusher?

Movable jaw of single toggle jaw crusher hangs on the eccentric shaft swinging from right to left. When the eccentric shaft rotates, the connecting rod will move up and down in a reciprocating way and it will drive the two thrust plates which will thrust the movable jaw move in a reciprocating way. In this way, the raw material will be crushed and discharged. This type jaw crusher adopts double crank linkage system. Although the movable jaw bears big crushing reaction, the eccentric and the linkage will not bear too much such force. Hence, in the mining machinery industry, huge and medium crusher is usually used for crushing hard material. Furthermore, when this type jaw crusher works, movement locus of every point on the movable jaw are circular arc with the eccentric shaft as the centre. The arc radius equals to the distance from the point to the axis. Radian of the upper part is small, and the lower part is big. So its crushing efficiency is not very high. The crushing ratio is usually 3-6.
