The transmission plate 20MG20.11.07.02 of the coal mill is usually installed on the output plate of the reducer and fastened by bolts. It is responsible for transmitting the power of the motor to the grinding plate and grinding roller to realize their rotational motion. The transmission plate 20MG20.11.07.02 drives the grinding disc to rotate through the transmission pin on the upper part. The grinding disc is the core component of the coal mill. It is disc-shaped and usually made of cast iron. The grinding disc is surrounded by the grinding roller, and its high-speed rotation causes the coal to be crushed and ground on the grinding disc Two scraper devices are symmetrically installed on the transmission disc and rotate with the transmission plate. These scraper devices are responsible for discharging the slag generated during the coal grinding process from the coal mill. It can be seen that the transmission plate 20MG20.11.07.02 of the coal mill not only transmits power, but also drives the rotation of the grinding disc and grinding roller, as well as the drive of the scraper device, to ensure the normal operation of the coal mill and the smooth discharge of coal powder. |
