Ball Mill Loading Guide Orbis Machinery, LLC.

25% is the maximum recommended product loading for Dry Grinding Applications. For Wet Grinding Applications the mill may be loaded up to 60% of cylinder total capacity (See below) CYLINDER LOADED WITH 50% MEDIA AND 40% PRODUCT (Based on Cylinder’s Total Capacity). 30% empty space in cylinder.

Add to this another 45% to 50% above the ball charge for total of 58% to 63% product loading. This level of liquid loading should leave some air space above the liquid to allow for expansion of the liquid as it heats up during the milling process. So as a rule of thumb we use a maximum of 60% liquid loading. See our Size Reduction Options

Once the quantity is finally determined, you can simply load the mill with the total amount of solids during the initial mill charging. With proper solids loading of about 25% solids (red), the grinding media (gray) will always have product to impact between the pieces of media.

A guide to maximising ball mill circuit classification

The function of the classification system in a ball milling circuit is to maximise the percentage of solids in the ball mill which require more grinding (coarse), and minimi se the amount of material that is already at target size (fines).

where d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
