How to Prevent Crusher Choking
It is apparent that the choke-point in the crushing chamber we have been discussing is at the discharge level, or immediately above it. It is equally clear that the unit pressures in such a chamber increase progressively from the top, down, reaching their maximum value at the choke-point, where the voids are at a minimum.

crushing cavity (Evertsson, 2000). Crushing liners are subject to wear; regular replacement and wear compensation are required. To provide maximum throughput, reduce wear, and minimize the crusher stresses, a mode of operation wherein the crusher inlet is fully covered with feed material (choke feeding) is recommended (Evertsson, 2000).

However, the CSS is set manually by an operator. Operating cone crushers at the choke-feed point is recommended by manufacturers because this approach gives a more consistent product sizing, maximizes throughput, develops a uniform wear profile, and extends the liner life (Bearman and Briggs, 1998, Ma et al., 2016).

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.
