The coal is processed and crushed to increase the efficiency and protect environment. In order to use coal more rationally, efficiently and effectively, the coal need to be processed and crushed into different sizes, 0 ~ 25 mm particle size for coal gas stove , 25 ~ 8 mm for steam locomotive, 25 ~ 6 mm for the industrial furnace, and coal power plant requires grain coal of 0 ~ 25mm.
Coal mill for producing slack coal
The particle size of slack coal is 0 ~25 mm. The slack coal is often used as combustion agent in steel company, thermal power plant, etc. The consumption of coal is quite large in thermal power plants. Take a 1 million kW thermal power plant for example, coal consumption amounts to 11,000- 13000t a day, which takes 60% ~ 80% of the cost for generating electricity. It is advisable to adopt appropriate coal mill for coal grinding. This can not only improve the utilization of coal, but also contribute to energy saving, environmental protection, economic benefits.
Grinding mill selection for thermal coal power plant
Pressure roller grinding machine, improved version of Raymond milling machine increases the performance stability and enhances the grinding fineness and efficiency.
Trapezium mill is based on and improved from Raymond milling machine and Pressure roller grinding machine, its performance is more superior. From the roll installation to the pressurization system design, the higher level of technical concept can be seen. Trapezium mill has replaced the traditional Raymond milling machine in the market, and features high capacity, stable operation. It has become the most common types of grinding machine.
Vertical grinding mill produced by precise control can process large quantities of materials and it features precise grinding size, and mass production. It has become the favorite equipment for large enterprises. Because of its large capacity and complex technology, it is not suitable for small and medium-sized enterprises.
The above are the most common grinding mills. With increasingly worsening environment, coal power plants should utilize coal more efficiently. This matters not only the profits of the power plant, but also the social development and environmental protection.
New Working Mode for Opencast Coal Mine
With global scientific and technological progress, the coal industry is changing from labor-intensive into capital and technology-intensive. The coal technology has also transformed from mechanized production to automatic control. Robot or artificial intelligence combined with expert is the new way for coal mining.
In order to solve the problem of small coal mine area and inconvenient transport of equipments, SBM, based on 20 years' production experience and several years' research, manufactures the world-class high-quality crawler type mobile crushing plant. It is made by impact crusher, jaw crusher, cone crusher, vertical impact crusher, conveyor, belt conveyor etc. It can meet different requirements "screening after crush" and "crush after screen". The crushing process can be divided into two phases "coarse and fine", and three phases "coarse, middle and fine". Moreover the mobile crushing plant can operate independently and jointly with great flexibility.
Mobile crushing plant has changed the past old way of coal processing mode in coal industry. It improves the efficiency of integrative coal treatment and highly recommended in coal and mining industry.
