Coal Steel Ball Mill Rotating Speed
What are on earth the factors of influencing the revolving speed of a ball mill?And how to give full play to the role of a ball mill? In fact, no matter which kind ball mill it is, a ball mill, a energy saving ball mill, a large ball mill, or a planet ball mill using in the university laboratory,a cement ball mil using in the cement production, the working principle of them are all basically simalar.So, the factors of affecting the revolving speed of them should have in common as well.

The working principle of ball mill: The ball mill grind materials at the driving of revolution and autobiography and relying on the friction and collision of the grinding balls in grinding bowl .The higher the revolving speed, the greater the function of the friction and the collision.So when the ball mill works at the formal condition, the discharging grain is basically proportional with the revolving speed of the ball mill.
In different mineral industries, the effects of a ball mill's revolving speed is also different. For example, in coal mine industry, the revolving speed of a ball mill directly impact the movement of the steel ball and cinder-blocks and the grinding process of the coal.If the cylinder body rotate at a very low speed, the coal and the steel ball can't be brought up,they will stay only in the bottom ,which leads a small rolling mill coal output.On the oppposite, if it rotate at a very high speed, the centrifugal force of the coal and the steel ball is greater than their gravity,the steel ball and coal will rotate together with the cylinder body without the function of grinding the coal.
The revolving speed of the ball mill can make the cylinder body steel ball up to a maximum height, at which time the ball mill has the most impact and achieves a best effect of grinding coal. However, in the actual work, the revolving speed of the ball mill is limited by the ratio of transmission device and other external conditions,which make it can't reach the most suitable height, so it is generally easier to close to.
