The Wear Runner Plate, also called the guide plate, is installed inside the VSI crusher impeller. There are 3 plates on the top and 3 on the bottom, for a total of 6 plates, which are distributed radially.

ZTA ceramic wear-resistant material has 10 times the wear resistance of high manganese steel and 10 times that of high-manganese cast iron.

During operation of an impact sand making machine, replacing the distributor plate and lower guide plate requires disassembling the machine cover, which takes approximately three workers and at least half a day to complete. If using distributor plates and lower guide plates made of ordinary technical materials for stone and sand production, their service life is approximately 150 hours. If the machine runs for 18 hours a day, the machine cover needs to be disassembled and the accessories replaced in less than ten days. This significantly increases the customer's production and maintenance operating costs and wastes valuable production time.

However, using ZTA ceramic material distributor plates and lower guide plates:

Their service life can be increased by 5-10 times or more.
