Crusher bulk materials can be broken must meet requirements within the maximum strength of material strength to the crusher can handle it. In addition, in the process of crushing roll crusher, crushing chamber should prevent iron and other non-broken material into them. When the feed material crushing when mixed together, there are a variety of materials strength inequality, high strength material strength material will protect small mobile crusher, thereby reducing the strength of the material crushing small probability and product size. And because of the strength of the liner resulting in the crushing chamber is not uniform force hammer crusher, eventually leading to uneven wear lining, affecting the normal operation of the crusher. Therefore, to improve the efficiency of the crusher and improve parts of the equipment the forces full play lamination broken during crushing functions in the production process should try to ensure uniformity requirement for feed material strength. According to expert analysis broken pyramid concept, when bulk materials crushing volume accounted for more than 40% can be completely laminated crushing in the crushing process. In addition, according to the case full feed extrusion type jaw crusher and a hopper to the uniformity, when the material filling degree of 55% can fully meet the requirements of laminated crushing. Broken pyramid approach can achieve energy saving purpose of crushing equipment. In order to maximize the energy efficiency of the crusher, laminated crushing feed need to meet certain conditions, as we have above conditions. Studies have shown that the crusher, when bulk materials at 6-10, more obvious energy saving equipment. Generally, feeding equivalent average particle size is usually about half the allowable maximum feed particle size, thus feeding layer of material around the stratum level of 2. When the crusher blockage height of 93 mm, the average particle size of the material can reach 9.45 mm, thus feeding the material layers may be determined as 9.8 layer, blocking layer material to achieve the best feed requirements of layers. Thus I find it difficult, in the crusher, the closer the blockage layer of material to feed the more layers to meet the optimal requirements for the material layer, the crusher will be able to achieve greater energy saving purpose. Mine crusher is an important mining equipment, mining crusher into hammer crusher, jaw crusher, impact crusher, impact crusher and so on. Different mining crusher performance and price vary. When buying mining crusher price is the object of widespread concern. Some people think that the high price of mining crusher mining crusher is good, this statement is not entirely correct.
