Feed-hopper level estimation and control in cone crushers
A common practice is to regulate the feed-hopper material level h in order to guarantee the choke-fed conditions. There are indications that higher feed-hopper level will result in smaller product size and higher throughput especially in a crusher, and this property could possibly be used to control size reduction (Herbst and Oblad, 1985; …

Crushing devices hold feed material between two solid surfaces and apply sufficient force to fracture or deform that material. Primary crushing operations takes boulder size feeds (20 to 100 inches) and reduces the material to secondary crusher feed size (1 to 20 inches) or mill feed size (0.5 to 3 inches).
