Driving plate and scraper of the ZGM mill

key word:Heat exchange element


Product description

The drive plate is rigidly connected with the reducer to transmit torque. It is installed on the output drive flange of the reducer and is fastened with 30 M48 bolts and the output drive flange. The upper part is equipped with a grinding plate. When the mill is running, the output torque of the reducer is transmitted to the drive plate through the friction between the output drive flange and the contact surface of the drive plate, and the drive plate drives the mill plate to rotate through the upper three drive pins. In addition to transmitting torque, the drive plate also bears the upper loading force and the weight of components, and transmits the force to the reducer body and the coal mill foundation through the thrust pad of the reducer.

The drive plate is symmetrically equipped with two scraper devices, which rotate with the drive plate. The normal clearance between the scraper and the bottom of the primary air chamber is 6-10 mm. When the scraper is worn, the clearance becomes larger. The clearance can be adjusted through the fastening bolts of the scraper.
