The Ball Mill, B-101, grinds the 0.25 ore until it is in the range of 160 microns. The ore leaving the ball mill is sent to six hydrocyclones that separate the larger particles from the smaller particles. The top stream leaving the cyclone is 75% of the feed into it. This top product is 160 microns or less.

involve grinding). With Lloyds ball milling book having sold over 2000 copies, there are probably over 1000 home built ball mills operating in just America alone. This article borrows from Lloyds research, which was obtained from the commercial ball milling industry, and explains some of the key design criteria for making your own ball mill.
The ball mill feed is 60 percent plus 106 m. The ball mill discharge is 50 percent plus 106 um. The circuit CSE is (60 percent 50 percent)/2 55 percent. This is the estimated percentage of plus 106 m solids in the ball mill, and also the percentage of the ball mill power effectively applied to the grinding of the coarse ...
Jun 19, 2015 The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum chunk size, product size as P80 and maximum and finally the

grinding. Each of these theories was useful in the design and scale up of ball mill operations, however they told little of the expected size distributions, and most importantly gave no indication of liberation. Later work done by Hukki (1975) attempted to show the validity of each theory within a certain particle size range.
SAG mill was reduced considerably. Further more, a 7% decrease in ball mill power draw from 4,843 HP to 4,491 HP (3,613 kW to 3,350 kW) was observed. This equates to a 24% decrease in ball mill unit energy consumption from 11.13 kWh/ton to 8.43 kWh/ton. The design of shell lifters and pulp lifters far exceeded expectations. Based on data collected
