Ball Mill Wear Rate

Pontificia Universidad ólica de Chile

The Media Charge_Linear Wear_Ball Mills spreadsheet was designed to estimate the Linear Wear Rate Constants for a ball charge in a Conventional Ball Mill, as a function of its known dimensions and basic operating conditions. Also, the spreadsheet allows for the calculation of the typical Grinding Media Consumption Rate indicators; that is, gr/ton, gr/kWh, kg/hr or tons/month. Theoretical

Modelling and simulation of ball mill wear -

Wear is associated with the comminution mechanisms found in the ball charge profile. It is assumed that ball mill wear occurs in each of three comminution zones, with adhesive wear found in the crushing and tumbling zones and abrasive wear arising in the grinding zone. Wear rates are proportional to the energy dissipated in these zones as predicted by the charge motion model. Three laboratory case studies are investigated followed by one full-scale example in a wet milling

Mathematical model of ball wear in grinding mills

01.03.1986· Experimental wear rate. Curves 1, 2, 3 correspond to a 3.7 m by 4.9 m ball mill, with three different ball qualities, and curve 4 corresponds to a 2.9 m by 3.7 m ball mill, both with grate discharge of 19.1 mm (0.75 in) nominal openings. Equation (7) gives, for zero-order wear rate, the number of balls of any size d at time t in the mill.

Ball Mill Wear Test - 911 Metallurgist

01.07.2017· Corrosion-resistant materials, the nickel-base alloy, Hastelloy C-276, and the stainless steel, type 316, had good wear resistance in the small ball mill where impacts were small. In the large ball mill, however, the wear rate increased about 10 times.

Modelling and simulation of ball mill wear -

Wear rates are proportional to the energy dissipated in these zones as predicted by the charge motion model. Three laboratory case studies are investigated followed by one full-scale example in a wet milling context. Simulation results are compared with experimental data from which real-system predictions are presented. The use of these results provides the possibility of optimizing ball mill

Table 1 from A comparison of wear rates of ball

The Ball Mill Abrasion (BMA) test was developed by the University of Queensland Materials Performance group to simulate the high stress abrasion conditions experienced in production ball mills. It gives accurate predictions of the service life of wear resistant alloys in mill liner and grinding media applications. In this paper the BMA test methodology was applied to investigate the wear rates

how to estimate the wear rate for Ball mill - Page

08.12.2009· 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. More simply and quite adequate is to keep a
