1. Add some grinding aids in ball mill can improve the production capacity of about 10%, generally use the triethanolamine as grinding aid, and the additive amount is about 0.04 %-0.1% of the mill materials.
2. According to the noise of ball mill, adopting electric ear to control electro-magnetic vibrating feeder, china vibrating feeder, pendulum feeder, feed grizzly or belt feeder, and control the right amount of material in the ball mill and automatically adjust the feeding speed and evenly add material to make the grinding volume within the ball mill always in the best condition, so as to improve the milling output.
3. To strengthen ventilation inside the ball mill. The inside ball mill has a wind speed when it works, so the powder in the micronized grinding process can be taken away by air to improve grinding efficiency. The mill has different ventilation rate due to the grinding of different material, generally, the ventilation rate is 0.3 - 1.0m/s. The production of high strength grade cement should use low-speed of ventilation rate, on the contrary, the bigger speed ventilation rate; should be used.
4. Water spray: ball mill generally produce a lot of heat when its grinding cement, the atomized water spray into the mill in high air-pressure can effectively take away the heat inside the mill to cool the ball mill. The water spray to ball mill is determined by the temperature inside the mill, generally, does not need spray when it is below 1000C. Spray through the grinding head or grinding tail are both OK.
