They break large rocks, ore, or other materials into smaller, more usable pieces. This equipment reduces the material by means of compressive force, impact, attrition or shear that are specific for the type of crusher being used. The main function of a rock crusher is to generate particles of similar sizes.

3. Feed Ore properties. The physical and chemical properties of the ore have a significant impact on the jig gravity separation process. The density composition of the ore determines the selectivity of the material. The greater the density difference between light and heavy minerals, the higher the separation efficiency.
