Raw Material Ball Mill

Center drive and side drive are two common drive modes for a ball mill. Center drive grinding mill means the motor shaft extends along the axis of mill body while side drive has a motor located on the side of the mill and torque is transmitted via the girth gear which is bolted on the flange of the mill body.. Materials are fed into the mill at a fixed flow rate along the shaft-less screw of ...

Grinding Media Wear Rate Calculation in Ball Mill

Ball Mill Ball Wear Projection In any mill, the rate at which the weight of any ball decrease is directly proportional to its weight. In any mill, the rate at which the diameter of a ball decreases is directly proportional to its diameter.

Optimization of mill performance by using

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, is

(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, contributing 10 – 15 µm/hr wear for softer ores and 20 µm/hr for abrasive gold, copper

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. 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.

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

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.
