For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54". By sizing the Jaw Crusher slightly larger than the largest feed size, you reduce the risk of large lumps getting stuck in the crushing chamber or sitting on top of the crushing chamber, stalling production.

It is important to choke feed the crusher, keeping the crushing chamber at full capacity. Trickle feeding results in uneven wear and poor output. You also need a mix of large and small stones in the chamber; uniform size leads to wear and waste. To ensure good shape, feed a long fraction (5-32 mm) into the crusher to aid inter-particle breakage.
