As the ball wear rate depends directly on the surface of the media charge a small variation in power will lead to an important increase of wear rate the risk of underloading or overloading the mill is an additional factor a direct measurement of the ball level in the mill more accurate than power readings as well as a control of it
Ball hardness is in the 60–67 hrc range they wear better than 440c stainless steel and throughhardened carbon steel they are also recommended for applications where a throughhardened steel ball is needed in larger sizes and larger they are sometimes packaged with a very light oil finish to reduce rust due to humidity sae

Dec 08 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 estimated more simply and quite adequate is to keep a record of material ground and of charge added periodically to cover a given level of mill
Half the density in a ball mill filling rate unchanged the weight of grinding balls will be half sand mill vertical sand mill and ball mills best feature is lower wear loss size ranges
High hardness surface hardness of casting iron balls is to hrc good impact toughness impact toughness of chrome balls is more than 3jcm low broken rate the actual broken rate is not higher than 1 good wearresistant gton in cement industry g in gold mines eo castings grinding balls are widely used in mining power plant cement and magnetic materials
High–low double wave ball mill liners – these are a refinement of the wave liner figure 5 this was applied to cadia hill gold mine through evaluation of their existing wear profile and wear rate and provided a more consistent wear profile through the liners working
In a ball mill the rate of wear of the liner is difficult to determine and can vary greatly according to such factors as the type and amount of the charge and the percent of solids therein the size density hardness and quantity of mill balls and the rate of revolution of the ballmill container read

Mill type overview three types of mill design are common the overflow discharge mill is best suited for fine grinding to 75 – 106 microns the diaphram or grate discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns the centerperiphery discharge mill has feed reporting from both ends and the product discharges
Oleg d neikov in handbook of nonferrous metal powders tumbling ball mills tumbling ball mills or ball mills are most widely used in both wet and dry systems in batch and continuous operations and on a small and large scale grinding elements in ball mills travel at different velocities therefore collision force direction and kinetic energy between two or more elements vary

The differential equation is solved for wear laws of the form wear rate per ball ∝ r2 δ where r is ball radius δ 0 gives the bond wear law and δ 1 gives the davis wear law methods of determining δ are illustrated experimental data are presented which show that δ 0 for some cases of wet milling δ 1 for the two mills reported by davis and δ 2 for a case of wet milling the reason for this wide
The rods grind the ore by tumbling within the mill similar to the grinding balls in a ball mill rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded the heavier rods acting upon the lifters and liners result in greater wear on the mill
They are available in two grades—10–13 chrome surface hardness ≥ 60 hrc core hardness ≥ 58 hrc and 14–18 chrome surface hardness ≥ 62 hrc core hardness ≥ 60 hrc they have a very rough black finish which quickly wears off during initial milling after
