The ball mill is an open gear transmission device, equipped with gears and inner and outer covers, but the sealing performance is still poor. When the bushing bolts near the large gear ring are loose, the leaked mud easily enters the gear meshing surface, destroys the lubricating oil film on the tooth surface, and generates great impact noise ...
