Crushing machine is widely applied in many industries such as mining, metallurgy, construction, Highway, Railway, water conservancy and chemicals production. Between the edge of the soft phase to achieve the technical approach is to organize the process of crushingequipment, selective crushing, and the impact of the traditional uniaxial compression or different, there is the principle of distinction, he incurs the broken material shall bear the full volume of the material layer in the extrusion, while the stress caused by the edge of the crystal or ceramic, material block should bear the combination of load, includingtensile, shear, bending and torsion, these requirements and the physical properties of the rock, can be used to accomplish a variety of different crushing methods .
(1) block of material can withstand the purely mechanical impulse load, its value is significantly lower than thedestruction of value. The grinder may be the program:
1) by the mechanical agencies of the crushing chamber for material blocks the use of full compression, such asvibrating cone crusher;
2) the surrounding liquid or gas medium pressure changes, such as pipes, pressure tanks, etc.;
3) the material or block each other several attacks on the impact of a plane;
4) rapid rotation of materials, etc., this method is relatively simple, containing a variety of rocks and elastic-plasticmaterial components are valid.
(2) vibrating at different frequencies or in the liquid and gas in the surrounding medium impact energy acting on thematerial, can also lead to soften the edge between the particles. Tensile stress is due to some shock waves in avariety of edges through the ability of mineral particles to be absorbed. The current widely used crushing machinery are jaw crusher, impact crusher, Vertical shaft impact crusher, hammer crusher, roller crusher and combination crusher, etc.
(3) for different size or line of thermal expansion (contraction) coefficient of ore or a non-uniform thermal properties,can take advantage of thermal processing.
(4) the use of mineral components have different characteristics, you can choose to absorb the electromagneticvibrations (caused by stretching electrical, electromagnetic-induced stretching along the conductive surface of theelectrical breakdown phenomena such as electricity, water management role), the material used for electric, magneticor electromagnetic processing of rock.
