Coal Mill

Coal mill is the equipment that is used to crush the coal and grind it into the coal powder. It is the important auxiliary equipment of pulverized coal furnace.  The grinding process of the coal is the process that the coal is crushed and its surface area is in increase. 

Coal Mill

To add the new surface area must overcome the binding force between solid molecules, which requires the consumption of energy. The coal is made of pulverized coal by the coal mill mainly through the three ways of crushing, shredding and grinding. Among the three ways, the energy consumption of the crushing process is the smallest while that of the grinding process is the most. The milling process of the various coal mills contains two or three ways of the above-mentioned. According to the rotational speed of the working parts of the coal mill, it can be divided into the low speed coal mill, medium speed coal mill and high-speed coal mill.

Features:

1. It is featured with reliable operation, continuous operation and large production capacity;
2. It has fewer transmission parts and the maintenance cost is low;
3. It has high efficiency and high output.

Coal mill is mainly used in the coal milling industry. In the operation of the coal mill, it is inevitable to generate the noise. The following is the ways to control the noise of the coal mill. Firstly, to reduce the noise at the sound source and there are many ways from this aspect such as the damping acoustic treatment in the cylinder; the second is to control the noise from the noise transmission routes: it mainly includes the development of the fixed acoustic enclosures or assembled acoustic enclosures with sound insulation.
