01/01/2000· Magotteaux has developed an improved system to automatically add grinding balls to grinding mills, the Magotteaux Automatic Ball Charger (ABC). The ABC adds relatively small weighed increments of balls, typically 100 kg, as required, rather than the large increments, 1,000-10,000 kg, that are common in manual charging systems. The Magotteaux ABC works with a mixture of ball sizes in the range of V2" to 5", making it possible to customize ball …

optimization of the ball charge in a grinding mill. What is the effect of low ball full on grinding efficiencyone of our clients is thinking of the future and has bought a ball mill that will be the right size someday, but is very large nowI know what happens to mill power from adjustments to critical speed and balls charge what i dont know

Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary greatly within the ball charge. Frictional wear or rubbing forces act on the particles, as well as collision energy. These forces are derived from the rotational motion of the balls and movement of particles within the mill and contact …

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or change volume can then be read off the …

Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include: Speed of mill rotation; Mill diameter; Mineral density;
