The Suitable Maximum Feed Size of Ball Mill

Ball mill grinder is most efficient when the maximum feed size is less than 2' and iron contamination is not a factor. These ball mills are sized from 2hp to 450hp for wet grinding and from 2hp to 500hp for dry grinding. Particles of different sizes and densities, when revolved in a cone will classify themselves with the largest pieces at the point of the greatest diameter. The shape of the conical ball mill provides a classifying action within the mill resulting in increased efficiency and lower power consumption.

Ball mill grinder is the most robust design in the industry. Fuller-traylor mill is the most robust Ball Mill Design in the industry with installations through 27' in diameter. These heavy-duty ball mills feature hydrostatic lubrication with either gear or gearless drive arrangements. Fuller-traylor ball mills have been manufactured in both trunnion and shell-supported arrangements. We also offer a more cost effective mill line called the ft series mills.

There are literally thousands of Ball Mills in use throughout the world, many of them in the cement industry. Few installations have a comprehensible method of controlling and recording exactly what ball size distribution is in, or should be in, the Ball Mill. As mills are supplied for ever increasing capacities, the ball size distribution and wear exact a tremendous effect on the profitability of producing finish cement. Improper size distribution or filling level of the ball charge can easily reduce the efficiency of grinding (possible production rate) by 5% to 20%. Relating an efficiency loss of only 5% for a mill with a capacity of 150 Stph, results in a loss of saleable cement at $90/Ston of $5.0 million per year. Online, real time information from the grinding process has aided in the attempt to reach peak performance, but for many grinding installations, maintenance of the grinding media remains in the dark ages.
