How to Size a Ball Mill -Design Calculator Formula

15/05/2015  In general, therefore, the required mill power is calculated using the following equation. where n is the number of efficiency factors, EFi, used and fo is the feed rate of new ore to the mill. The power calculated from equation 2 can be looked up in published tables (Rowland and Kjos, 1978) and the correct mill

Effect of ball and feed particle size distribution on the ...

01/06/2018  Mass fraction M3 vs. milling time for various grinding times at a media fill level of J = 20% (a) feed size = -1700 + 850 μm (b) feed size = -1 180 + 850 μm. Fig. 8 shows that the small 10 mm ball size is superior in generating more material in the fines size class, from both feed sizes used.

Feed Size VS Ball Size - Grinding Classification ...

From my limited knowledge, yes there exist a relation between the feed size (F80) and the optimal ball size especially in a ball mill operation. Moly-cop tools for evaluation and optimisation of milling circuits can give/predict a very fair ball size to be used for a specific milling circuit taking into consideration the ore (density, bond work index) and operational parameters(mill speed, mill filling degree and effective diameter). Smaller balls are effective in milling

Ball Mills - an overview ScienceDirect Topics

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

THE OPTIMAL BALL DIAMETER IN A MILL

The ball impact energy on grain is proportional to the ball diameter to the third power: 3 E K 1 d b. (3) The coefficient of proportionality K 1 directly depends on the mill diameter, ball mill loading, milling rate and the type of grinding (wet/dry). None of the characteristics of the material being ground have any influence on K 1.

Small Ball Mills for Sale - 911 Metallurgist

Ball mills are customarily divided into categories that are mainly defined by the size of the feed particles and the type of grinding media. Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter.

The ball mill is in a closed circuit loop with sump and sieve bend. The sump has a feed of 60.1% solids,water addition to sump is 100 cubic meters per hr and outflow from sump constitutes 49.1 % solids.This feeds onto a sieve band which has an under-screen flow of 42.9% solids. The overflow from the sieve bend (56.1% ) feeds into the ball mill which has a water addition of 67 cubic meters per hr.The ball mill
