At present, for crushing ore, it is mainly with the help of mechanical. It has five common broken ways.
Crushing method: using two broken faces pressure when pressing the material, the material broken. The characteristic is the applied force increase gradually and have a large scope.
Split pieces method: using the sharp teeth of the splitting wedge material, the material broken.
The characteristic is the applied force more concentrated and have local breakdown.
Broken method: the material in the crushing, because of the relative orientation of the bending strength of concentration, the materials fracture and broken. The characteristic is by the splitting point in addition to the external force strength, but also by the role of bending force, thus, it’s easy to crush ore.
Milling method: crushing the material on the relative movement of the face, resulting in shear stress on the material. This force is acting on the mineral surface, suitable for fine grinding of materials.
Attack method: the crushing force is instantaneous when acting on the material, so it is also known as power broken.
Now it is usually used the combination of several fragmentation methods for crushing ore of broken machinery.
