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, 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 will protect little strength materials, thereby reducing the strength of the material crushing small probability and product size. And because of the strength led to the crushing chamber liner force is not uniform, and ultimately can lead 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 crusher broken pyramid 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 cone crusher, the closer clogging layer of material to feed the more layers to meet the optimal requirements for the material layer crusher equipment, crusher will be able to achieve greater energy saving purposes. Crusher general handling larger pieces of material, product coarser, usually greater than 8 mm. Its structure is characterized by a gap between the broken pieces, do not touch each other. Crusher can be divided into coarse crusher, the crusher and fine crusher. In general mill processed materials smaller product size is fine, up to 0.074 mm, even some fine. The structure is characterized by crushing members (or medium) contact with each other, the use of the medium is steel balls, steel bars, gravel or mineral mass. But some machinery is with both crushing and grinding action, such as from the mill. ∮5.5 × 1.8 米 cap from the mill processing ore particle size of up to 350 to 400 mm.
