Jan 07, 2015· ~ Nael Shabana 201015~ 4.5 Measurement of Wear: Ball wear can be measured by weighing an entire charge before and after grinding a known tonnage of materials. With new balls sample of given size can be weighed before and after grinding a given tonnage and, assuming uniform wear per unit of ball surface, the total charge wear can be estimated.

In the work cited the calculation of such wear has, to a first approximation, been carried out and it is suggested that the relationship between rate of wear and relative hardness of ball and particle has the form shown in Fig. 8.2, whilst the relationship between rate of wear and quantity of powder in the mill has the form of Fig. 8.3.

There into the wear particle size is large, the same will accelerate the grinding media ball wear. When the feed rate of the ball mill is increased or the grinding rate is required to be too fine, the service efficiency of the ball mill wear-resistant grinding media ball is in a lower range, thus increasing the power consumption of the ball ...

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 ...

Table of ContentsData on Ball ChargesBall Mill Ball Wear ProjectionRecapitulation of Ball Wear FormulasPractical Application of Theoretical Conclusions In the previous discussion the fact was established that the work done by a ball when it strikes at the end of its parabolic path is proportional to its weight and velocity; then, since the velocity may be considered as constant for all the ...

It is assumed that ball mill wear occurs in each of three comminution zones, with adhesive wear found in the crushing and tumbling zones and abrasive wear arising in the grinding zone. Wear rates are proportional to the energy dissipated in these zones as predicted by the charge motion model.

There into the wear particle size is large, the same will accelerate the grinding media ball wear. When the feed rate of the ball mill is increased or the grinding rate is required to be too fine, the service efficiency of the ball mill wear-resistant grinding media ball is in a lower range, thus increasing the power consumption of the ball ...

One of the major problems regarding the use of ball mills is to balance the size distribution of grinding media into the mill, which is determined by the speed of consumption and rate of replacement, as the wear of the grinding balls requires their substitution at intervals.

This paper presents a conceptually simple derivation of grinding media mass wear rate model. An experiment of milling onemedia in ball mill was designed to reveal the relation between media mass wear rate and the contacting points of the media with the other media and/or mill wall and the pressure acting on the point.
