The ball mill feed ratio is the weight and the weight of the material grinding mill than a warehouse. It shows a certain amount of grinding media loading process under much grinding mill feeding amount of memory, and also shows in the normal functioning of the feed mill degree of uniformity. The material is filled in a ball mill grinding gap in between, the theory that when the gap mill by grinding the material in grams of filling, the maximum production capacity of the mill, so the most efficient use of energy.
Experiment confirmed that when a ball mill grinding gap is of the filling material, the material was 14.2% by weight of the weight of the grinding, when the ball feed ratio equal to about 7. When the mill (b warehouse mill) functioning in small coarse material surface exposed positions ball half ball is appropriate, in the body should be buried in the fine grinding abrasive materials warehouse below 1-2cm.
The ball mill feed ratio is too large, it will increase the friction between the grinding media and the impact between the grinding media and liner futility losses, the power consumption increases, consumption increases ball lower yields; If the ball is too small to feed ratio, indicating grind memory material too, will produce a buffer, will reduce grinding efficiency.
1. In mineral production, to adjust the load of the ball mill grinding media. Practice has proved that the increase because of ball mill load of the body, and can not achieve the effect of increasing production, loading the most suitable grinding bodies should seek to control the ball with the amount of 95% of rated load.
2. Optimized gradation ball mill.
3. Strengthen cement mill ventilation and sealing system to reduce air leakage. Proper ventilation, can be discharged within the powder cement ball mill, reducing over-grinding, while discharging steam to reduce the sticky ball. In addition, the mill is connected to the elevator, separator machines and other production equipment for sealing, improving air lock effect.
4. Reduce the grinding temperature, strengthen grinding system cooling. Grinding system temperature is high, partly dehydrated gypsum cement quality, increasing the electrostatic adsorption powder, paste inside the ball mill increase, so too serious grinding, so pay attention to the surface of the cooling system.
5. Regular clearance, catch up on the ball. Beneficiation production process, grinding and grading is very critical and important part, grinding machine is a high energy consumption, low operating efficiency, fault-prone equipment, grinding machine condition monitoring, not only can improve equipment efficiency and productivity, reduce energy consumption, and reducing failures, but also improve economic efficiency, to ensure normal production.
