You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or equation to get the RPM that corresponds to 75% for that mill diameter.
A ball mill is a cylindrical device that rotates around its axis, partially filled with the material to be ground plus the grinding medium (usually ceramic balls, flint pebbles, or stainless steel balls). As the mill rotates, the grinding media crushes and grinds the material against the inner surface of the mill chamber, creating a fine powder
High temperature of the ball mill will affact the efficiency 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded Reasons

Low speed: At low speed, the mass of balls will slide or roll up one over another and will not produce a significant amount of size reduction. High Speed: At high-speed balls are thrown to the cylinder wall due to centrifugal force and no grinding will occur. Normal speed: At Normal speed balls are carried almost to the top of the mill …

Obtain charcoal. You can use standard charcoal that you buy to cook with your grill, which you'll need to grind to a fine powder. If you're a purist, make your own charcoal by filling a metal drum with 3-inch pieces of willow or another wood, then placing the drum in a bonfire with a loose lid on top (to allow for airflow). Keep the bonfire piping …
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.
