• The crusher should be choke fed so that the crushing chamber is full all the time. This is important, especially in fine crushing. Choke feeding maximizes the amount of multi-layer crushing, and improves wear shape and crushing efficiency. 1. Choke feed level for GP secondary crusher is at the level of the mantle fixing nut 2.

If you find the crusher operating in a crushing force overload condition (ring movement) or a power overload condition (excessive amperage), open the crusher setting slightly, but try to stay choke fed. The advantage of staying choke fed is the fact that there will still be rock-on-rock crushing and grinding taking place in the crushing cavity.
