| The grinding plate 20MG23.11.09J.61 in the coal mill, also known as the grinding disc or grinding ring, is a key component used to grind coal in the coal mill. The main function of the grinding plate is to grind coal. It is located inside the coal mill. The coal is impacted and ground on the grinding plate to become fine powder. In addition, the grinding plate also has the function of protecting the coal mill cylinder, preventing the cylinder from being directly impacted and rubbed by the grinding body and materials. In a multi-bin mill, the grinding plate separates the grinding body through the partition plate to prevent large particles from rushing to the outlet of the mill, thereby controlling the flow rate of materials in the mill. When the coal mill is working, the raw coal falls from the coal feeder through the coal drop pipe from the center of the coal mill to the rotating grinding disc in the mill. Under the pressure of three independent grinding rollers, the coal blocks are crushed into coal powder particles of different sizes. At the same time, the hot air flow is not only used to dry the coal powder, but also provides energy to transport the ground coal powder to the coal powder burner. Qualified coal powder is sent to the primary air coal powder burner, while the coarse coal powder falls from the separator to the grinding bowl for re-grinding. The design and material of the grinding plate are crucial to improving the coal grinding efficiency and the uniformity of coal powder, which directly affect the performance of the coal mill and the combustion efficiency of coal. In summary, the grinding plate plays multiple roles in the coal mill, such as grinding coal, protecting the cylinder, controlling the material flow rate and improving the coal grinding efficiency. It is the core component of the coal mill to realize its functions. |
