· That is why it needs to be monitored throughout the crusher’s lifecycle. As excessive wear can cause a 10–20% reduction in production, it is important to find the optimal time for the jaw turn or change in terms of cost and benefit. Again, with the same scenario with C130, we would have approximately a 70 stph reduction in production, in

· In 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.
