In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

Understanding Comminution Compression Versus Impact Crushing. Compression crushers can easily process hard and abrasive material and, due to their crushing method, expel fewer fines while doing so, thereby increasing the efficiency of the circuit. This is because cone crushers utilize interparticle crushing, where rocks are also compressed

The comminution is an important unit operation in mineral processing, this process requires application of forces. Mechanical comminution can be accomplished in mainly 2 ways. 1. Crushing: the most used crushing machine are the jaw crusher, cone crusher, impact crusher, and hammer crusher. 2. Grinding: crushed material can be further ground in grinding mills like ball mill, rod mill, hammer

The breakage of material in cone type gyratory crushers is traditionally regarded as relying upon single particle breakage. In the last ten years the emphasis has shifted with manufacturers trying to generate higher degrees of interparticle breakage. Increasing the degree of interparticle crushing is claimed to improve crushing efficiency and product shape.

Roll crushers consist of two or more adjacent rolls placed parallel to each other and rotated in opposite directions. Single roll crushers are also available which rotate a single roll against a fixed breaker plate.

A Jaw Crusher is one of the main types of primary crushers in iron ore processing plant. The rectangular or square opening at the top of the jaws (feed opening) designates the size of a jaw crusher. For instance, a 24 x 36 jaw crusher has a opening of 24" by 36", a 56 x 56 jaw crusher has a opening of 56" square. Primary jaw
