Mills. Figure 2 shows a cutaway view of a Babcock and Wilcox MPS Pulverizer. Ring-Roll and Ball-Race Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a Ring-Roll Mill the rolls may rotate while the ring is stationary).

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.

The wear of grinding balls by impace in a mill is not nearly as evident nor ... whereas the rate of ball wear during abrasive processes is proportional to the ... rate of ball wear.
Secondary Grinding Ball Mills experience 1-2 years of liner life, depending on tonnage/ball size. Normally Lifter to Plate ratio is 1:2.Tertiary Grinding Ball Mills experience up to 4 years of liner life. Since, all the mills are unique in their operation and the practical sense in which they run, we do wear measurement during every shutdown.
Explain the role of ball mill in mineral industry and why it is extensively used. ... Measurement of charge height is a convenient method to estimate charge volume. Generally : ... Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter.

The selection of an optimum top ball size for a large SAG mill is determined by several factors: wear rate, particle breakage effectiveness and liner damage. This example shows how 3D DEM can be used to provide quantitative input on each of these factors. In this case the performance of three different top ball sizes (125, 150 and 175 mm) are ...

Ball hardness is in the 60–67 HRC range. They wear better than 440C stainless steel and through-hardened carbon steel. They are also recommended for applications where a through-hardened steel ball is needed in larger sizes (½" and larger). They are sometimes packaged with a very light oil finish to reduce rust due to humidity.

Feb 06, 2011· Re: how to estimate the wear rate for Ball mill. As per the experience, for 3 chambers 1000 HP cement mill, the given below thumb rule of wear rate and Kwh was found to be practicle.
BALL MILL DRIVES, LOADED, WAVEFORM LEVELS, SEPTEMBER 1A 1B • Above is a plot of the waveform vibration levels at both the 1A & 1B ball mills when loaded (acceleration). • Note how waveform levels at 1A ball mill are higher than that at 1B ball mill for every measurement and especially at points PIH PIA (pillow block, coupling-end bearing).
The ball mill is a key piece of equipment for grinding crushed materials, and it is widely used in production lines for powders such as cement, silicates, refractory material, fertilizer, glass ceramics, etc. as well as for ore dressing of both ferrous and non-ferrous metals. The ball mill can grind various ores and other materials either wet or dry.
cycle of mill liners. The liner wear reading can be used to calculate available volume inside the mill as the inside mill volume for ore grinding is a function of volume of mill liners. The measurement of liners can also be used to estimate the grinding performance and the monetary output of the mill.
