mill media wear rates from laboratory based ball mill tests 8. It was shown that laboratory mill tests could predict plant media wear rate to within 20. Whilst this is still a wide margin of error, this variant of the BMA test shows promise. The BMA test is non-standardised in the sense that the reference used is the average wear rate of all ...

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

May 01, 2014 For the 50 mm balls the respective increase in power and capacity is 28 and 42. It is interesting to note that, to maintain the plants present operating capacity of 54TPH, a J of 11 would suffice for 30 mm balls and this would significantly save on mill power and wear loss.

Industrial Solutions Velix Thyssenkrupp

The maximum wear rate on a tip liner is where the screw dips into the material flow. With conventional screw designs wear is directly related to material processing. Wear, i.e. loss of screw length, in a conventional design results in a larger non-grinding area at the bottom of the mill. So we challenged ourselves to develop a new tip liner ...
