Importance of Crushing Process in Grinding

The raw materials that need crushing in the production of cement industry come mainly from mining and thermal firing. Accordingly, prior to the pulverizing, the inside of these materials have varying degrees of the lattice defects and fine cracks. Under the action of external mechanical forces, the internal cohesion of material is damaged; stress wave has propagation to all the directions and the stress concentration is produced in its internal defects, cracks, lattice interface, etc., so that the material first crackle along these fragile surface to be crushed cost of plant and machinery for iron ore processing. Meanwhile, within the particles of different sizes after being crushed, there will be different degrees of lattice defects and fine cracks due to the different external mechanical forces, which lay the foundation for the energy-saving and high-yielding of the ball mill grinding process of. This means that: the external force gives the material kinetic energy, and converts…
