The application of crushing machine in the cement industry

Since the reform and opening up, the rapid development of the domestic economy and promote the rapid development of socialist construction, in which the process of urbanization, the consumption of building products is huge, and one of them is cement. In the economic restructuring, the crushing machine in the comprehensive utilization of mineral resources in the technology occupies a pivotal position, with reasonable crusher machinery set up a reasonable production lines, the full use of all phases of the broken material, to achieve zero pollution emissions, will be the future trend of development.

First, crushing and its significance
Relying on external forces to overcome the solid material between the internal cohesion of the material, so that solid material damage, split. From large to small pieces, with coarse particles become fine powder process, known as crushing. The industry will be used to small pieces of the process of small pieces known as broken; the coarse particles become fine powder process known as grinding; crushing and grinding together referred to as crushing.
After the solid material is crushed, the internal crystal structure changes, the surface energy increases, the change area (specific surface area) per unit mass also increases, the speed of physicochemical reaction can be increased, the mixing is easy, and the homogenization effect is improved for drying, storage box transport to create favorable conditions.
For example cement production, the main raw material limestone is from the mining ore, small one is 300 ~ 500mm, large one is 1000 ~ 2000mm. Thus firstly they must be broken by crushing machinery. After grinding through mechanical grinding can be achieved. Each production of 1t cement, about 3 ~ 4t need to crush all kinds of materials, crushing process of electricity consumption occupy 60% to 70% of the whole plant power consumption.

Second, common crusher in the cement plant and its main crushing methods are as follows.
1. By squeeze the principle to operate is jaw crusher, rotary crusher and cone crusher. By impact the principle is a hammer crusher and impact crusher. Both the principle of shear and extrusion for small roll crusher and tooth cutting broken.
2. Hammer and impact crusher. Hammer and impact crusher is the most common models usage of the cement industry. Both rely on the impact of crushing materials, have a coarse, crushing the models. The main difference between the two is the hammer, the former is hinged on the rotor hammer, which is embedded in the rotor body of the plate hammer.

Therefore, it is very important to choose reasonable crushing machinery, simplify the crushing process of the whole plant, improve the traditional smashing operation and the operation level of the crushing post, so as to achieve high yield, high quality, low consumption and safety of cement production. Compared with the traditional crushing equipment, the PE / PEX jaw crusher, the PF impact crusher and the PCH ring hammer crusher produced by Henan Zhengzhou Mining Machinery Co., Ltd. have the advantages of high hardness, high hardness, broken power consumption, and so on, and sincerely welcome you to come to visit.
