WhatsApp: +86 18221755073In jaw crushers, the crushing force is generated by the movement of the movable jaw plate towards the fixed jaw plate. This force is a result of the mechanical pressure created by the eccentric shaft and transmitted through the toggle plate. The interesting thing is how these forces are applied to the material. The crushing force is not uniform.
WhatsApp: +86 18221755073Jaw crushers are operated to produce a size reduction ratio between 4 :1 and 9 : 1.
