subject: Crusher Holds An Important Place In Cement Industry [print this page] Crushing, that is external to the large particulate material into the process of small particles of materials, called its mechanical crusher. Where the external force of small particulate material into a powder material, called a comminuted or ground, referred to as grinding. It uses machinery is grinding machinery. Crushing and grinding together referred to ascomminution, the use of machinery referred to as grinding machinery.
In recent years, China's crushing industry in overseas demand driven began to catch on. With the advances in technology, broken machinery technology upgrading, its scope is wider and wider, not only for use in the mineral processing industry also can be widely used in the cement industry, the crusher is generally deal with larger pieces of material in the mineral processing industry, coarse grain size is usually greater than 8 mm. Its structure is characterized by a certain gap between the broken pieces, do not touch each other. The crusher can be divided into coarse crushing machine, crusher and fine crusher. Generally speaking, the smaller of the materials handled by the mill, the product particle size is fine, up to 0.074 mm, and even is even smaller. Its structure is characterized by broken parts (or media) contact between the media used is steel balls, steel bars, gravel, or ore block. However, some machinery is both crushing and grinding effects, such as self-grinder. 5 x 8 meters, since the mill processing ore particle size limit of up to 350 to 400 mm, product fine of up to 40% -200 mesh
The crushing of the cement: the cement production process, most of the raw material to be broken, such as limestone, clay, iron ore and coal, Limestone is the largest amount of production of cement raw materials, after mining the larger particle size, hardness, and therefore need to go through the crusher broken, such as jaw crusher, impact crusher machine, cone crusher, impact crusher ( sand maker). Their limestone crushing plays animportant role in the crushing of the cement plant material.
