The wear resistance of nano-ceramic wear-resistant materials is 6-10 times that of high-manganese steel and 3-8 times that of high-storage cast iron.

During the use of the impact sand making machine, the replacement of the two accessories, the distributor plate and the lower runner plate, requires the removal of the machine cover, which requires about three workers and at least half a day to replace. If the technical material distributor plate and lower runner plate are used for stone sand making, their service life is up to about 150 hours. If the machine is turned on for 18 hours a day, the machine cover must be removed and the accessories must be replaced once in less than ten days. This greatly increases the production and maintenance operating costs of customers and wastes precious production time.

However, the use of nano-ceramic material distributor plates and lower runner plates.

The service life is increased by more than three times, and it only needs to remove the machine cover once a month to replace the distributor plate and lower runner plate.
