In the process of cement production, coal mill, as one of the important equipment, is responsible for grinding and conveying coal powder, and its stable performance is directly related to the quality and efficiency of cement production.
However, after a period of time, the gap of the grate plate of the coal mill usually closes gradually, resulting in problems such as poor ventilation, accumulation of coal powder, and unqualified fineness, which in turn leads to the emergence of unfavorable factors such as the decrease of coal mill output and the increase of system wear.
In order to solve these problems, the new grate plate after structural improvement is applied in the improvement process of coal mill in cement plant. The improved grate plate of the coal mill adopts a horizontal slit structure, which has some significant features and advantages compared with the original vertical arrangement.
Firstly, the transverse slit structure can effectively improve the ventilation, and by changing the relative angle between the grate plate slit and the direction of movement of the coal mill, it improves the ventilation performance inside the coal mill, maintains good air flow, and reduces the pressure loss in the system.
Secondly, the transverse slit structure can effectively reduce the closing phenomenon of the grate plate slit, making the operation of the grate plate more stable, reducing the problem of coal powder accumulation brought about by the closed slit, and ensuring the normal transportation and grinding process of coal powder.
In addition, the lateral arrangement structure can also effectively reduce the degree of wear of the coal mill and extend the service life of the equipment.
The improved coal mill grate plate structure is applicable to various types of coal mills in cement plants, and has shown excellent adaptability in several coal mill retrofit projects in cement plants.
Cement plants are one of the industries where the improved coal mill grate plate gap structure process is mainly applied. In cement production, coal mills undertake important work tasks, and their stable operation is crucial to the efficiency and quality of the cement production process. By improving the grate plate gap structure, the cement plant can effectively solve the problems caused by the closed gap, improve the performance and service life of the coal mill, and thus improve the quality and productivity of cement production.
