It is important to pay attention to the scalp, which can improve efficiency. Increased current is to improve the speed; change the formulation to increase the strength and weight of the ball (to increase its inertia); the grinding time and efficiency are independent, because the efficiency itself is the amount of workload and time to improve the speed of the speed, and use the inverter , Modify the reducer (if there is a deceleration device), if it is a ball mill, the amount of water is also affected to the ball milling efficiency. The efficiency of the ball mill can be improved by adding a dispersant.
