crushing of ore mineralsCrushing in Mineral Processing 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 cr As a common building material, limestone is widely used in cement, decoration, building materials and other industries due to its wide source and low cost.In general, limestone processing into stone, the need to use the equipment that we often say crusher, also known as the shredder, stone machine, no matter what is called, in the final analysis is the limestone processing into the specific industry needs the size, particle size, then processing limestone with which machine is more appropriate? 1. Jaw crusher + impact crusher Jaw crusher is generally used for primary breaking operations, all kinds of soft and hard stones can be broken efficiently, for limestone this kind of low hardness material treatment effect is also very good;Secondly, the impact crusher itself focuses on soft stone crushing operation, and the impact crusher itself covers the plastic function, the finished stone particle is very good, is the ideal limestone processing equipment, both with high efficiency and high yield

Crushing in Mineral Processing

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.
