Ball Mill critical speed & Ball Mill Opeartion
1. Ball Mill critical speed
The ball mill critical speed of various Intermittence Ball Mills is in direct proportion with its diameter, the absolute figure of critical speed is hard to calculated, and now only the calculation formula on critical speed in theory is widely used. When the non-smooth lining plate is used, the filing ratio of ball load is among 40%~50%. When the ore-grinding concentration is larger, the grinding effect is close to the practical production.
SBM, the Ball Mill manufacturers in India design Ball Mill critical speed suitable for Cement,quartz,bentonite,limestone,coal,coke,graphite milling process.
2.Ball Mill Opeartion
Ball Mill repair and maintenance are crucial for assuring manufacture efficiency. If not maintained properly, ball mill run-time will be reduced causing substantial economic losses.
- 1. The operators must be qualified with the required technical knowledge, received technical training and fully understand the operating principle, regulations of the ball mill.
- 2. The operators should follow the operate principle and lubricate the requirement parts marked in lubrication picture. Untreated waste oil may not be used and keep lubrication points clean.
- 3. Pay attention to check the temperature of bearing not to exceed 60 and make sure every bolt not loose, no abnormal sound, uniform mining feed, steady water feed, normal current and voltage of motor.
- 4. To keep surroundings clean where the ball mill run. Every party should be clean unless it's running.
Ball Mill Appliciation
Ball mill grinding machine is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, ferrous and nonferrous metal and glass ceramics and other mineral production industries.
This the second time I pruchase SBM ball mill for kaolin grining process.The Ball mill Shibang supply for me bring me rich life.I like my partners Shibang company.
The ball mill is a really efficient tool for grinding dolomite into fine powder! And the company assisted us to Install and debug the equipment.
