The wear rate measured in gram per ton of cement produced is much higher for a ball mill than for a vertical roller mill. However, the unit cost for wear parts for a ball mill is much lower than for a vertical roller mill. For a ball mill grinding OPC to a fineness of 3200 to 3600 cm 2 /g (Blaine) the cost of wear parts (ball, liners and mill ...

Vertical roller mills (VRM) can replace ball mills or tube mills used for preparing coal. Today VRMs with capacities up to 50 tph are the dominant technology for coal grinding. According to MIIT, grinding media wear in a VRM will only be 5 to 10 g/ton of coal powder, as compared to 100 g/ton of coal powder in a ball mill.
The ball mill can grind various ores and other materials either wet or dry. There are two kinds of ball mill, grate type and overfall type due to different ways of discharging material. Many types of grinding media are suitable for use in a ball mill, each material having its own specific properties and advantages.
Grinding Media & Lining Media Liner Wear Rate Modelling & Prediction ... also leads to the fairly generally accepted conclusion that the rate of wear is proportional to the power absorbed in a mill. Thus it appears that the ball wear is, very roughly, proportional to both rate of production of surface and to power input to the mill. ...

Dec 08, 2009· Re: how to estimate the wear rate for Ball mill. Most practical way to by measuring empty height and calculating the % volumetric filling of grinding media.Alternative way to make track of mill main drive kW consumption reduction and add makeup charge according to the extent of fall in power consumption.
There is no standard solution for mineral industry and wear rate of grinding media varies from mine to mine, ore to ore and even for the same ore time to time. Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution.
2.3. Wear of grinding media. 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
The grinding ball is a material grinding media of ball mill and coal mill. Its' function is as an important component of ball mill under grinding and cutting effect brought by the friction between grinding balls and materials.Therefore,let's talk about the processes of matching the proper grinding balls for .
One of the economic factors of grinding is the wear of the grinding media.This is dependent upon the material used in its manufacture, method of manufacture, size of media, diameter of mill, speed of mill, pulp level maintained in the mill, rate of feed, density of pulp maintained, shape of the liner surface, nature of the feed, and the problem of corrosion.
