product size distribution for a ball mill

Ball size distribution for the maximum production of a

01/11/2015· Ball size distribution is commonly used to optimise and control the quality of the mill product. A simulation model combining milling circuit and ball size distribution was used to determine the best make-up ball charge. The objective function was to find the ball mix that guarantees maximum production of the floatable size range (i.e. − 75 + 9

Nov 01, 2015· The simulated product size distributions were found to display a close match with the measured product from an operational mill. Based on the maximum production of floatable particles, the best combination of make-up ball size was determined in relation to feed flow rate, feed size distribution and ball filling. EFFECT OF BALL SIZE DISTRIBUTION ON MILLING PARAMETERS.

01/06/2018· The mill product was then taken to a jones rifle splitter and homogenously separated into measured 100 g samples for sieve analysis. Using the -850 + 300 μm size class material, this procedure was repeated for all the grinding times considered. The standard sieve analysis technique was then repeated three times for each milling duration and the results showed very good reproducibility, within

grinding media size distribution in ball mill

The Azzaroni equation indicates that the correct ball size for the 2.93 m mill is 81 mm. Years of experience show that a 76 mm ball grinds the coarse particles most effectively. Ball size distribution is governed by the wear law of the mill and by the wear characteristics through the cross-section of the balls charged to the mill.

Calculate and Select Ball Mill Ball Size for Optimum Grinding

In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize “just in case”. Well, this safety factor can cost you much in recovery and/or mill liner wear and

effect of ball size in a ball mill stsylvainvolley

The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation of a with ball diameter was found to be of the form...

Ball mill Wikipedia

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the

Ball Mill Roller Press Systems for Cement Grinding . The finished product cement from this system has all been further ground in the ball mill, so it has wide particle size distribution and stable performance However, due to the fact that the materials rolled by the roller press are not sorted, a large amount of fine powder is returned to the roller press

Ball mill- factors influencing the size of product. Ball mill that works on the principle of impact is an efficient technique of size reduction through grinding. The size reduction is an important factor for many industrial applications as this process is carried out to increase the surface area, to intimate mixing and to improve dissolution rate, solubility, binding strength and dispersion

which can grind efficiently in a mill, c is the exponent which characterizes the ball size distribution. The condition for efficient grinding, defined by Eq. 7, will be fulfilled when the grain size distribution and the ball size distribution are the same, which means that the parameters of both distributions are equal in Eqs. 7 and 9: m c.
