If the ball mill cylinder rotational speed is low, the steel ball coal can't be brought up and rolling only in the lower, the grinding coal output is very small; On the contrary, if the ball mill speed is higher,the centrifugal force for steel and coal is greater than gravity,the steel and coal will be rotated with cylinder. However, in practical work of ball mill, the speed of the ball mill by the gear ratio and other conditions, the outside world is unlikely to be the best height, so they are generally close. As you all know, ball mill is the indispensable key equipment in mining mineral processing, and for ball mill, ball mill speed is the key to the efficiency of grinding factors.
If we check this out, we can find that cone crushers are going to make some change in order to make it lower in height and better in quality.the new type cone crushers are safer and easier in operation and are accepted by most home and abroad users. Zhengzhou taida adopted total new design theory and advanced crushing technology to meet all kind of needs for different crushing materials. It was proved with good performance in crushing, low consumption of energy and suitable for all kinds of mineral crushing.
In fact, whether it is ball mill, energy-saving ball mill, large type ball mill, or planetary ball mill in the university laboratory , cement ball mill for cement production, the working principle are basically similar. The higher the speed, the greater the effect of friction force and impact force, so in the case of the normal work of the ball mill, the discharging grain and ball mill speed is directly proportional basically. The working principle of ball mill is in the driving of revolution and an autobiography, relying on the grinding balls in grinding bowl friction and impact force to crush the sample.the speed of rollerball mill, which can make the maximum lifting height of the ball in the cylinder body. the ball will have the greatest impact and the effect of grinding coal is best.
