Working principle of crusher

Extrusion crushing: The working surface of the crushing machine exerts pressure on the materials sandwiched between them, and when the compressive stress on the materials reaches the limit of their compressive strength, they are crushed.

Splitting and shearing crushing: The edge of the crushing face wedges into the material to generate tensile stress inside. When the value exceeds the tensile strength limit of the material, the material splits and locally produces powder at the point of contact between the sharp edge and the material.
Bending, breaking and breaking: The materials sandwiched between the working surfaces are simply supported beams or multi-beams under the action of concentrated force, and the materials are mainly subjected to bending stress, but are subject to splitting at the contact of the working surfaces.
Extrusion-shear crushing: A combination of extrusion and shear crushing.
Impact crushing: Impact crushing includes the impact of high-speed moving crushing bodies on the crushed materials, the impact of high-speed moving materials on the fixed wall, and the mutual impact of moving materials.
