Feed-hopper level estimation and control in cone crushers

Cone crushers require tight feed-hopper level control because the recommended mode of operating is choke feeding, wherein the crusher inlet is fully covered with feed material (Evertsson, 2000). Failing to provide choke-fed conditions will result in higher crusher peak loads, erratic power (and pressure) profile, and excessive wear.
