Coal-water Slurry Ball MillTorque is transmitted to girth gear from the motor via the gearbox.The mill shell rotates under the action of this torque. There are grinding media in the mill body, which are raised to a height before falling back on the material to be ground during mill rotation.
J is the ball filling fraction. ρ charge is the overall charge density calculated as follows: ρ charge = total coal mass + ball mass / J ∗ Mill volume. α is the angle of repose, which is estimated to be about 35°. Mill capacity increases linearly with increasing ball load for both ball sizes within the considered range.
We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill. 6. 1.

According to available literature, the operating speeds of AG mills are much higher than conventional tumbling mills and are in the range of 80–85% of the critical speed. SAG mills of comparable size but containing say 10% ball charge (in addition to the rocks), normally, operate between 70 and 75% of the critical speed.
Coal water slurry ball mill is grinding equipment specially used for coal water slurry production. Its specifications, structure and working conditions must meet the requirements of coal water slurry production scale, production process characteristics, rheological characteristics, product particle size, and coal type characteristics.
Stresses, generated in the ball charge, increase, which may result in spalling of balls and blocking the grate discharge. Optimization of mill performance by using online ball and pulp measurements by B. Clermont* and B. de Haas* Synopsis Ball mills are usually the largest consumers of energy within a mineral concentrator.
Fig. 3. Rubber lining, grate mill. Ball Mill Charge volume. The mill power is approximately directly proportional to the charge volume within the normal range. When calculating a mill 40 % charge volume is generally used. In pebble and ball mills quite often charge volumes close to 50 % are used.
Residence time distributions (RTDs) were estimated by water tracing in a number of wet overflow ball mills (diameters 0.38 to 4.65 m) producing dense, coal-water slurries. In open-circuit mills of 0.38 m diameter and various length-diameter (L/D) ratios, the mean residence times of solid were also determined from measured mill holdups. Holdup increased …
Grinding mills, including SAG (semi-autogenous grinding) mills and ball mills, consume approximately 60-70% of the total energy cost of the entire mining operation. The mills are installed with large motors, up to 20+MW, which impart the required energy to successfully process many tonnes per hour and grind the rock to a powder size suitable ...
50% x 26% = 13% free space Add to this another 10%-15% above the ball charge for total of 23% to 25% product loading. So as a rule of thumb we use 25% solid loading. Empirical Check: Once the mill has been loaded and run for a few minutes, open the cover and look down into the mill.
