Coal Mill In Power Plant
Coal mill is one of the four main auxiliary coal-fired power plant, is the body of the pulverized coal preparation system equipment, mainly used for grinding various hardness of coal.At the same time can also be applied to cement, metallurgy, chemical industry of coal and ore raw material coal pulverizing system. Special coal mill in power plant is a new equipment, widely used in thermal power plant equipment.
Coal mill is the coal pulverized coal crushing and grinding into mechanical, it is an important auxiliary equipment of pulverized coal furnace. Quarry crushing and screening equipment malaysia Coal grinding process is the process of coal was broken and its surface area increased. To add new surface area, we must overcome the molecular bonding force between the solid, and requires energy expenditure. Pulverized coal into coal in the coal mill, mainly through the crush, crush and pulverization three ways. Crushing process energy consumption of the province. Trituration process is the most energy consuming. All sorts of coal mill in milling process are both the above two or three ways.
The performance characteristics of the coal mill:
1, large output, low power consumption. Coal mill uses squeezing and grinding the lowest energy consumption of grinding, the highest efficiency in the way of grinding ore, grinding ore grinding out of good material fineness, discharging granularity average at around 1 mm, large output.
2, medium wear small, high purity of products, parts, long service life. This is because the material layer of ore grinding principle of grinding roller do not direct contact with wear-resisting lining board, and its wear resistant materials with high alloy.
3, low noise (less than 70 db (a) no dust pollution, the system work under atmospheric pressure, grinding ore without direct metal collision, finished product recovery rate was 100%, and the basic saves the cost of environmental protection, more conducive to solve the problem of pollution.
4, easy installation, the machine to install no special concrete foundation, can save a lot of construction costs.
5, maintenance convenience, four rounds of grinding roller can tear open outfit independently. And layout in the grinding chamber. This layout and effective to avoid bearing because of the problems into ash. Greatly improve the stability of the equipment. Effectively reduce the enterprise production and maintenance costs.
6, gap between roller and plate convenient adjustment when grinding ore powder, gap adjustment in closed, without having to stop operation, the minimum clearance can be adjusted to 1 mm and the “edge” phenomenon will not occur.
7, roller grinding pressure adjustment is convenient, Price of quarry and mining crushing equipment simply by grinding closed to adjust the hydraulic equipment, can be convenient to adjust ore grinding pressure, so as to achieve the best effect of grinding ore powder.
8, stable and reliable operation, no vibration, filling grease, without having to stop operation, more suitable for need 24-hour production ore milling equipment manufacturers.
9, the difference with the traditional mineral powder grinding equipment several rounds of coal mill can pass without having to stop operating speed, clearance, pressure regulating pursuit of one machine with high yield. Effectively reduce the production power consumption, lower production costs. Using the enterprise product competitiveness.
