The mill feed size ore lime process of the impact on productivity is very large, the main reason is the feed size small, ore in mill stay within a short time, faster. The same situation in grinding fineness of ball mill, feed size is coarse, ball mill production capacity is low; to the ore particle size smaller, higher production capacity. But it should be noted: when the requirements of grinding product is coarse, mill productivity with feed size variation is obvious, and the requirements of grinding product with fine, mill productivity with feed size change is not too serious.
Compact structure, higher hardness of tiny crystals, ore difficult to grind. So this ore in the grinding process, the grinding mill time is longer, to ensure the grinding fineness requirements, but in general the main effects of treatment ability of ball mill. While the hardness of small or cleavage developed ore is easy to grinder mill, processing capacity of unit volume is high. Ore hardness is a factor that can not be changed. In production, the larger hardness ore, through the experiment to find out the discharge concentration, the returned sand amount of operating conditions such as the most suitable.
The grinding concentration must be strictly controlled, too large or too small will produce undesirable effect. The high concentration of the slurry flow rate is slow, and the grinding medium impact becomes weak, the overflow type lime grinding, the discharge granularity coarsens, and the mill may appear ' bloated ' phenomenon.We know that the lime mill bulging belly in addition will affect the lime mill work ability and work efficiency, and may even lead to the damage of lime mill. From here we can see that prevent bloating situation of lime mill is ignored, so we need to know what is in front of the aura of lime mill bulging belly.
