The ball mill's discharging granularity problem
The ball mill's discharging granularity problem
Generally speaking, the ball mill's discharging granularity can reach to 200 mesh. If compare with other machines, the discharging granularity can reach to 325-400 mesh. According to customers’ demands, we can control the discharging granularity to reach the engineering needs. These are SEBON concluded in the process of operation practice.
First it must fully understand the grinding fineness factors. Summed up, the factors including: Undressed ore hardness, crushing granularity , Craig sieve mesh , Give ore amount, ball mill model, number of steel balls, steel ball size scale, ball mill foils wear,
ball mill speed, the sorting machine speed, the sorting machine spindle hoisting height, the sorting machine blade wear, the sorting machine overflow weir discretion, the sorting machine open discretion, the sorting machine open size, extension in-flight openings discretion, grading in-flight openings size, return sand water flow size, ball mill in size, ball mill row ore mouth place blunt water size etc.
Undressed ore hardness: Different ore has different hardness, this factor is fixed to the same ore, and it is also unable to adjust. But in production, in beneficiation technological requirements, we can undertake reasonable ore matching to make ore matching size uniform, lump ore, powdery ore matching reasonable steady as far as possible. In addition, in ball mill belt gives the ore place, it may leak ore due to long wear of the belt. The leakage of most cases is powder grinding, and it should be add to the ball mill timely. If long time piled up and concentrated on add, it can cause ball mill gives the ore uneven, and then cause manufacturing unstable. Especially it is difficult for mineral separation, and powder minerals and block mineral nature identical frequently.
