In the field of extractive metallurgy, mineral processing, also known as ore dressing, is the process of separating commercially valuable minerals from their oresselling of operation of cone crusher, · A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones. A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear-resistant mantle, and the enclosing concave hopper, covered by a3D free fall rock size sensor, · An elongated form of the rock, which is known to be amplified by a number of crushing techniques such as the jaw crusher and to a lesser extent by the gyratory crusher (Brown and Marek, 1996), amplifies this measurement bias. The ore geology is the other.
