#### how to estimate the wear rate for Ball mill Page 1 of 10

Dec 08, 2009 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.

#### Mathematical model of ball wear in grinding mills II

Oct 01, 1987 The effect of wear rate law, design factors and operating conditions on the size distribution of balls and steel consumption were studied via simulation techniques and a method is given to combine data from marked ball tests and screening of the mill charge in order to determine unambiguously wear kinetics in industrial mills.

#### Ball mill media optimization Metcom Tech

determine what media size(s) addition will maximize any given depending on size of balls and ore being tested. • Ball surface wear rate is approximately constant, but with variations due to wear rate in a continuously operating mill. Slurry volume occupies the 40 percent voids volume in the 34 percent

#### Optimum choice of the make-up ball sizes for maximum

Sep 01, 2013 In Eq.,the value of Δ depends on the wear law. If the ball wear rate is proportional to ball weight, Δ = 1. If it is proportional to ball surface area, Δ = 0. Austin and Klimpel's analysis of the experimental data showed inconsistencies in the data, but Δ = 0 is a good approximation for ball milling.

#### (Received: February 1, 2016; Accepted: November 4, 2016)

SAG mill balls experience both significant abrasive and impact wear due to their large (75 100 mm) diameters. Ball mill balls experience a greater number of impacts, but at lower magnitude than SAG mill balls, due to the smaller ball size, and smaller mill diameter. Feeds are typically highly abrasive,

#### Grinding Media Wear Rate Calculation in Ball Mill

Apr 29, 2017 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.
