OEM OR ODM-500mm~8000mm Ring Gears. The large ring gear is the main component of the ball mill, it needs to drive the entire barrel for a long time. The large gear mounted on the end cover of the ball mill is also called a large ring gear. Generally, it is divided into a full ring gear, a half ring gear and a quarter ring gear.
For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged. Pulp is usually 75% solid (crushed ore) and 25% water; pulp is also known as ' slurry '.

Inspect shafts and housings for runout of shoulders and bearing seats, and use precision-grade locknuts. 5. False Brinelling. Rapid movement of the balls in a raceway while equipment is idle wears away at the lubrication. In addition, a lack of rotation in the bearing does not allow fresh lubricant to return to the spot.
· HEM is a roughing technique that uses a lower Radial Depth of Cut (RDOC) and a higher Axial Depth of Cut (ADOC). This spreads wear evenly across the cutting edge, dissipates heat, and reduces the chance of tool failure. Besides dramatically increasing tool life, HEM can also produce a better finish and higher metal removal rate, making it an
