Wear Tests on Grinding Balls

run in a Marcy ball mill approximately used balls I in. in diam in a mill I ft in 3 ft id determine the weight loss caused by wear alone. 3. After marking, the surface defects such as scaling and decarburization were removed from the test balls by a " wear-in " in a small ball mill for a sufficient time to remove metal to a depth of at least 0.040 in. below the original surface of the ball

how to estimate the wear rate for Ball mill Page 1 of 10

08/12/2009· Re: how to estimate the wear rate for Ball mill. Hey; 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

Optimum choice of the make-up ball sizes for maximum

01/09/2013· Further, the ball size distribution in the mill is not a simple parameter that can be controlled directly, as it depends on the make-up ball charge and wear rate. Therefore, the industrial practice of determining the make-up ball sizes comes down to experience. However, there is a great deal of information that describes the variation of the grinding kinetics with the ball size and the ball

Consumption of steel grinding media in mills A review

Current understanding of factors influencing wear loss of steel balls in mills is reviewed. Media wear arises as a consequence of complex interaction between a range of variables related to processing conditions, the characteristics of the media, as well as the ores or slurries, and is not well understood as yet, despite extensive study over the last 50 years and more. The three basic wear

Grinding Media Union Process

They have great wear rate generally better than 90% or 99.5%. 99.5% alumina balls have the highest alumina content for a moderate price. The .5% impurity is MgO that is added to inhibit grain growth during sintering in the kiln. There is less than 0.1% silica in the media. 99.9% alumina balls are made of very pure and reactive (expensive) raw materials. They are for high purity alumina
