efficiency of ball mill

A ball mill generally loses its grinding efficiency remarkably at fine grinding. This is because fine particles from ground materials agglomerate and adhere to the mill liners or grinding media as coating, reducing the impulsive force of the mill.

The centrifugal force caused by rotation of barrel brings the steel balls to a certain height and impact and grind the materials.

What are the dimensions of the ball mill you are looking at? 40% ball charge is quite high (unless you are looking at a small mill). A difference (duty vs. maximum) of 5% to 10% is fairly typical and you would likely struggle to perceive an energy efficiency difference between the two operating points.

The article offers suggestions on how to improve the ball mill grinding efficiency. It proposes several changes in operating practice by using appropriate make-up media size, operating the mill in a cataracting mode and controlling the milling circuit in a modified mode.

The ball mill is the most common ore grinding technology today, and probably more than 50% of the total world energy consumption for ore grinding is consumed in ball mills.

Ball mill,Ball mills,Ball mill machine,Ball grinding mill ... Energy Saving Ball Mill Ball mill, an energy-saving grinding device, is widely used in mineral processing, building materials and chemical industries.

A ball mill is a type of grinder used to grind and 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.

8-3 Centrifugal force outward Fc mp& 2 Dm 2 (8.1) & is the angular velocity, mp is the mass of any particle (media or charge) in the mill and Dm is the diameter of the mill inside the liners. Gravitational force Fg mpg (8.2) The particle will remain against the wall if these two forces are in balance ie.

Ball Mills have been successfully run at speeds between 60 and 90 percent of critical speed. ... To achieve a reasonable efficiency with the Ball Mill, it must be operated in a closed system, with oversize material continuously being re-circulated back into the mill to be reduced.

obtained for sample IV (processing in ball mill). From Figures 10 and 11 it occurred that the efficiency of processing in ball mill is high for short period of grinding time (till 5 minutes) and fine granulated feed.

Ball mill. A typical type of fine grinder is the ball mill.A slightly inclined or horizontal rotating cylinder is partially filled with balls, usually stone or metal, which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30%.

a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account. As well, mills with different length to diameter ratios for a given power rating will yield different material ...
