How to use the ball mill to control the grinding fineness? Ore Milling Equipment fineness is one of the many factors that affect the ore dressing index. The size of the grinding fineness directly affects the grade of concentrate and the recovery rate of the product, which can directly reduce the beneficiation cost and improve the economic benefit of the plant. How do we carry out proper dressing? As far as possible the choice of ore size uniform, massive, powder ore ratio is reasonable. What if the ball mill is on a sieve? Most of the leakage is the case of powder ore, this part of the ore leakage must be added to the ball mill as soon as possible, if the long stacking, will cause the ball mill to ore uneven, causing production instability. How does the Ore Milling Equipment refine the coal mine? SBM recommends that, according to the requirements of grinding fineness, appropriate to adjust the level of the weir of the grading machine, if the requirements of grinding fineness thinner, can be welded on both sides of the grading machine at a certain height of angle iron, To adjust the grading machine weir level.
