Study on the Method for Collecting Vibration Signals from

Jul 15, 2014· Because the ball mill system is of nonlinearity, long time delay, and time-varying, the fill level of coal powder cannot be measured accurately, which leads the mill to be operated usually under very uneconomical condition to prevent the coal blockage, and the automatic control system is also hard to accomplish steady operation of the mill.

Ball Mill Loading

The starting point for ball mill media and liquid charging is generally as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 45% to 50% above the ball charge for total of 58%

Ball Mills

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

Optimization of mill performance by using

As the ball wear rate depends directly on the surface of the media charge, a small variation in power will lead to an important increase of wear rate. The risk of underloading or overloading the mill is an additional factor. A direct measurement of the ball level in the mill, more accurate than power readings, as well as a control of it, is
