Limestone is the raw material with a large amount of cement production. After mining, it has larger particle size and higher hardness, so it needs to be broken by limestone crushing plant, the most commonly used limestone crushing equipment includes jaw crusher, impact crusher, cone crusher, sand making machine, etc.
In the mineral processing industry, the production cost of crushing and grinding operations in the concentrator accounts for more than 40% of the total cost, while the production cost of grinding operations accounts for more than 40% of the total cost, and the investment of grinding equipment accounts for about 60% of the total investment of the concentrator. Most of these materials have to go through crushing and grinding. It can be seen that crushing and powder engineering play an important role in the national economy. In recent years, China's crushing industry, driven by the strong overseas demand, has become popular.
In the cement industry, the grinding cost of cement plant accounts for about 20% of the production cost, the power consumption of crushing machinery accounts for about 10% of the total power consumption of the whole plant, and the power consumption of powder machinery accounts for 60%. The combination of crushing and grinding is referred to as crushing and grinding, and the machinery used is referred to as grinding machinery. The process of turning small particles into powder materials by external force is called crushing, destroying or grinding, or grinding for short. The machine it uses is called grinding machine. The second stage is cement grinding: cement grinding is the post process of cement manufacturing, and it also consumes more power. Cement crushing: in the process of cement production, most raw materials need to be broken, such as limestone, clay, iron ore and coal.
Crushing is the process of turning large particles into small ones with external force. The machine used is called crusher. Its main function is to grind the cement clinker (and gelling agent, functional regulating material, etc.) to the appropriate particle size (expressed by fineness, specific surface area, etc.) with a pulverizer, so as to form a certain particle gradation, increase its hydration area, accelerate the hydration speed, and meet the requirements of cement paste coagulation and hardening. In recent years, with the development of science and technology, many cement enterprises are pursuing low consumption and high production. On the basis of ball mill, new research and development have been made on multifunctional mill LM series vertical roller mill, which fully realizes the new grinding process of cement enterprises and realizes low energy consumption and high energy consumption. The annual output of brittle materials in China has reached more than 1.5 billion tons, including about 240 million tons of iron ore, more than 100 million tons of nonferrous metal ores, 260 million tons of non-metallic minerals, more than 30 million tons of chemical minerals, more than 400 million tons of cement, and more than 470 million tons of limestone for building materials. With the development of science and technology and the upgrading of crushing machinery technology, its application scope is more and more extensive, not only used in mineral processing industry, but also widely used in cement industry, and has a significant role in it. With the rapid development of contemporary social economy, the social demand and production scale of various metals, non-metallic, chemical minerals, cement, building materials and other materials are expanding day by day, and the amount of materials requiring crushing and grinding is increasing rapidly.
