The development of global mining industry depends on the growth of science and technology.   In mining industry, the mining equipments take greatly important roles.   All the mining jobs need mining equipments.   The equipments are changing rapidly, which is also up to the growth of science and technology.   In this way, science and technology is the key to the development of global mining industry.

Upgrade its scope more widely, not only for use in mineral processing industry while also widely used in the cement industry, and has a significant role in its breaking, is to use force to large particles of materials into the process of small particles of material, the use of machinery called a crusher.   Where the small pieces with the force grain materials into the process of powder material, called crushing or grinding, grinding short.   Machinery it uses is called grinding machinery.   The crushing and grinding combined together referred to as the broken ground, short grinding machinery used machinery.

The average total cost to 40 percent, while investment in ground equipment, concentrator of the total investment accounted for around 60 percent.

In the cement industry, cement the role of broken grinding costs about 20 percent of production costs, broken machinery, and the total power consumption accounts for about 10 whole plant percent, While the powder mechanical power 60 percent.

Cement crushing: in the cement production process, most of the material to be broken, such as limestone, clay, iron ore and coal.

The largest amount of cement is the production of raw materials, the larger the particle size after mining, high hardness and therefore need to be broken through the crusher, such as broken jaw crushers, impact crusher, cone crusher, impact crusher (sand making machine) and so on.   The broken limestone crushing of the material in the cement plant occupy more important position.

Cement grinding and then a stage is: cement manufacturing cement...
