The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills …

The ball mill filling can be estimated from the geometry of the ball charge at rest. However, in terms of the angle θ, ball filling (J B) may also be computed as indicated by Austin et al. . These relationships are illustrated in Figure 7.5. The charge centre of gravity may also be located in a similar graphical way as shown in Figure 7.6.

The starting point for ball mill media and solids charging generally starts as follows: 50% media charge. Assuming 26% void space between spherical balls (non-spherical, irregularly shaped and mixed-size media will increase or decrease the free space) 50% x 26% = 13% free space. Add to this another 10%-15% above the ball charge for total of 23% ...

01 Mills Rotary Speed and Filling Ratio. Overflow ball mill's rotary speed influences the motion state of steel balls. Under the low-speed circumstance, steel balls drop after rising to a certain level, with grinding as the main acting force supplemented by the impact.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

3. Friction between the lining and the grinding media. 4. Internal friction mill charge. Figure: Grinding media 4.4.1 Grinding Ball Charge in Mills: According to Levenson, the optimum grinding ball charge should be r - 0.16D The degree of ball charge varies with in the limit of 25 and 45%. A ball charge below 25% causes sliding of the balls.

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. Introduction Ball mill is an efficient tool for grinding many materials into fine powder.

Jan 04, 2012 Ball mill charge becomes measurably swollen only when there is a buildup of large unground material in the ball mill or when the density of the pulp in a wet mill is extremely high. Although these conditions are seldom encountered, it is recommended that ball mills be ground out prior to shutdown for measurement of the charge level.

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,
