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 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

US 30,000 Our smallscale miner's Ball Mills use horizontal rotating cylinders that contain the grinding media and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the "toe" of the mill when the force of gravity exceeds friction and centrifugal forces.
The simplicity of the Basket Mill system allows for very high material yields from batch to batch, as high as 99%. This means less cleanup and a reduction in waste solvents. Premixing, dispersion, compounding and dilution are all accomplished in a single unit that requires less space, less time and less energy to achieve bigger results.
