For ball mills operating in closed circuit, the circulation load is monitored by weighing the flow of reject material from the separator. These measures ensure you achieve optimum mill performance, giving you the quality, efficiency, safety and reliability that you need.
Cement Ball Mill Structure. When Ball Mill is working, raw material enters the mill cylinder through the hollow shaft of the feed. The inside of the cylinder is filled with grinding media of various diameters (steel balls, steel segments, etc.) when the cylinder rotates around the horizontal axis at a certain speed, Under the action of centrifugal force and friction force, the medium and the.
The batch ball mill is a kind of ball milling machine which discharges the material in one time according to the nature of the material. Different from continuous ball mill, batch type ball mill grinds powder by times and adopts intermittent operation. The batch mill is mainly used for the mixing and grinding of materials, with uniform product fineness and saving power.
The closed-circuit grinding system formed by a ball mill and a separator is a type of widely used cement milling system in cement plant. There are many factors that may affect the ball mill’s working efficiency and product quality during the operation.

There are two basic types of ball grinding systems open circuit and closed circuit. In the open circuit system, the mill product has the fineness required for the next stage. In the closed-circuit system, the mill product is classified in a separator in a fine fraction that is then taken to the next step and a thick fraction that is returned.
Double helical feeders used in closed-circuit with classifiers Spout feeders preferred when using a closed-circuit with classifying cyclones. Cyclones are typically installed above the mill and thus the cyclone underflow is fed to the mill by gravity. Discharge System. One exit unit Exit about 5 – 110 cm lower than the center line of the.
