In ball mills, the role of Grinding Balls on minerals is generally considered as impact and abrasive. According to reports in the literature, in the ball mill with a certain speed and filling rate, the grinding effect mainly depends on the position of the ball in the mill and the type, size and proportion of the ball. In running ball mill, Grinding Balls is distributed according to a certain rule, that is, along the axial direction, from the mine end to the discharge end, the ball diameter is gradually reduced; in the radial direction, the ball diameter gradually decreases from the inside to the outside. Therefore, in the running ball mill, coarse ore particles will be preferentially crushed, that is, the big ball mainly relies on impact and crushing to crush the coarse ore particles; and the pellets mainly grind and crack the fine particles by fine grinding, Form a big ball hit the big grain, small ball grinding grain state.
Quality, which is the most important determining factor in the choice of forged Grinding Balls products. If a manufacturer forgings Grinding Balls of substandard quality, the result does not meet the practical requirements of use, then the price is low, the purchaser will not choose such a forging Grinding Balls manufacturers as their partners. The quality of forged Grinding Balls is a rigid requirement that will not be met until it is eliminated. This, on the other hand, calls for forging Grinding Balls manufacturers to pay attention to the quality of their products.
Prices, prices are not only important for forging Grinding Balls manufacturers, but also important for buyers. The current Grinding Balls forging market, although the price competition is more frequent, but the overall cost is still there. Therefore, as a buyer, of course, hope that the lower the price the better, but from the forging Grinding Balls processing terms, this is impossible. Forging Grinding Balls is therefore overpriced or underpriced.
Therefore, for a given ball mill and under a certain ball load, if the big ball is too much, the number of balls is small, the total ball surface area is small, the chances of attacking the mineral particles are small, and the medium-level yield is large, Fine phenomenon; the other hand, if the ball too much, the number of balls, although the total surface area of the ball load increases, but coarse ore grinding is not fine, the fine level yield will not be large, but will increase the crushing, Cause the so-called under-wear and over-wear phenomenon. In this case, if the ore particle size is too coarse or too large to the amount of ore, it will make the classifier back to the amount of sand and coarse ore particles multiplied, undermining the normal operation of grinding and grading, resulting in ball mill so-called " Bloat "ball icon. From this we can see that it is very important to determine the size of the Grinding Balls for the largest ball and the smallest ball when the ball mill first loads the ball.
