The cylindrical mills had the following dimensions: 19- by 36-inch unit type, 19- by 36-inch sectionalized with a grid, 24- by 24-inch, and 24- by 36-inch. Three conical mills were used. Two of these were made by lining a 24- by 36-inch drum. The first was lined so that the dimensions were 22.5 by 16.5 by 36 inches.
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. Pulp is usually 75% solid (crushed ore) and 25% water; pulp is also known as ' slurry '.
