The significance of grinding machine in cement industry

In recent years, China’s crushing industry sells well pulled by overseas demand. With the advancement of technology, crushing machinery upgrades technology, its scope is more and more widely, not only used in the mineral processing industry, also widely used in the cement industry and has a significant role.
In the mineral processing industry, the concentrator comminution job production costs, on average, accountsfor more than 40% of the full cost; and grinding equipment investment accounted for beneficiation about 60% of the plant’s total investment.
In the cement industry, cement comminution accounts for about 20% of the production cost, breaking machinery power consumption accounts for about 10% of the total power consumption of the whole plant, the powder mechanical power consumption account for 60%.
Cement-crushing: in cement production process, most of the raw materials need to be broken, such as limestone, clay, iron ore and coal. Limestone is raw material that has the maximum amount to produce cement; it has larger particle size, high hardness after mining, so it needs to go through crushing by jaw crusher.
Another stage is cement-grinding: cement grinding is the final cement manufacturing process, and also a power-up processes. Its main function is to grind cement clinker (and gelling agent, performance tuning materials, etc.) into appropriate particle size, and form particle size distribution, increasing area of hydration, accelerate hydration rate, to meet cement paste condensation and hardening requirements.
With the rapid development of the contemporary socio-economic, social demand and production scale of a variety of metals, non-metallic, chemical, mineral, and cement, building materials and other materials grow fast, the amount of materials need comminution rapidly increases. Since the 1990s, the world Comminution amount of material each year more than 10 billion tons. China’s annual production of brittle materials has reached over 1.5 billion, and powder engineering has played a huge role in the national economy.
