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.
