Re: how to estimate the wear rate for ball mill. most practical way to by measuring empty height and calculating the volumetric filling of grindinge way to make track of mill main drive kw consumption reduction and add makeup charge according to the extent of fall in power consumption. reply.

The grinding media in the ball mill is required to have great wear resistance and impact resistance. the material to make the grinding media must be hard, wearresistant, and not easy to crack. burr and crack are not allowed on the surface of grinding media, and the out of roundness of the steel ball shall not exceed 2 of its diameter.

Grinding balls in alloy steel rolled andor stamped. we supply balls on a wide and complete range of hardnesses, with different hardness profiles, to maximize the grinding performance in wear rate and impact endurance, at a regular wear and with tailormade alloys.

Grinding media are used in the grinding mill of the cement plants to grind materials. advantages of using wear resistant grinding media: the high chrome grinding media in the cement plant improves the wear resistance, abrasive wear performance, and pure abrasion life of coarse aggregate while maintaining particle stability.

Grinding media lining media liner wear rate . 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.

Maximize this rate. the mill grinding efficiency can also be calculated by taking the ratio of the mill grinding rate over the materials grindability as measured in the lab. mill percent solids optimization has thusly been achieved (mcivor et al., 2000). for media sizing, maximizing the mill grinding rate on a given ore is equivalent.

Mill feeding increasing together with acceleration wear for balls, table (2) diaphragm and the linings (mill interior parts) it is wellknown fact when using grinding aid in cement ball mills the feeding increase above the designed mill feeding capacity of the mill which means it can have 100 th cement ball and using grinding aid feeding.

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.

Re oppsite classification of grinding media. reverse classification may occur in ball mill. if your grinding media wear rate is high and of chamber is too low. it is indicate by mill frequently chocking problem. if your mill is going to chocking condition, mill ol blain low , main drive kw too much variation ( lower side to normal ).

Regarding operations, in a ball mill, the grinding media has a higher rate of wear about the rollers and table in the vrm. in ball mills, it is essential to monitor its performance via axial testing to ascertain that the media grading is right and that there are enough topsize media to grind the mill feed materials.

The grinding medium should provide maximum performance, minimum wear rate and highest grinding transfer to cost ratio (jankovic, wills, amp; dikmen, 2016). it is important to predict the rate of mill.
