You cannot exceed the maximum allowable feed size for the cone crusher model. The feed size will depend on factors such as the closed side setting, eccentric throw, and head diameter. Exceeding the max feed size will lead to premature crusher failure. Use the minimum CSS and throw to determine the largest feed material allowable.

Size reduction control of cone crushers has received fairly little attention over the past few decades. Consequently, the most common control objective is still to regulate the crusher load (crusher power or crusher main shaft piston pressure) or the closed side setting (the shortest distance between crushing liners), not the actual size reduction.
