The effects of percent solids, mill loading, and grinding time on product size distribution and ball wear were studied in a laboratory ball mill for a taconite ore. Mild steel balls and HCLA steel balls were used to examine the role that ball hardness play in grinding. Net production of −44-µm (−325-mesh) material reached maximum at 70% solids, whereas the ball wear decreased as pulp ...

Bauxite. Lead – Zinc. Rock phosphate. Metal slag. Coal. 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.

High-Chrome media has a superior performance and creates steady milling conditions due to its low wear rate. For each specific alloy there is a constant hardness of all grinding media. This creates a positive influence in the down-stream process. high-Chrome media is suitable for both wet and dry ore applications in ball mills and tower mills.

Key words grinding media wear rate ball mill abrasion test 1 skew roll forging and die and sand casting Balls for forged steel and up to 50 less wear in … Steel grinding balls VMG The grinding balls have …

Using proper speed has a cascading effect where the charge and grinding balls roll over one another, thus developing maximum milling action with minimum wear of grinding media and lining. If the ball …

Therefore, compared with the SAG mill, the diameter of ball mill,the particle size and the ball size is smaller;the running speed is relatively decreased and the filling rate is higher. The grinding balls mainly impact and grind minerals by cascading, and can't discharge unless the balls reach the specified size,which required high wear ...

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.

Then in ball-wear formula (25), T = 6.9/K Log10 Da/Db; but from (29), K = Rt/Wt. Then T = 6.9Wt/Rt Log10 Da/Db T is 1 day, Wt is the original weight of the ball charge, and Rt is the ball wear for one day. Then Log10 Da/Db = Rt/6.9Wt are all known, and it is only necessary to solve for Db, the diameter of the balls to be added.
