ball milling rate

COMMON EQUATIONS FOR OPTIMAL PERFORMANCE

The feed rate is measured in inches per minute (IPM) and is the result of the cutting feed (IPR) and the spindle speed. Speed and feed considerations are crucial for optimal results. Incorrect speeds and feeds can cause increased chatter poor finish hamper production chip packing damage the cutter etc. COMMON EQUATIONS FOR OPTIMAL PERFORMANCE

Mill (grinding)Wikipedia

Ball mill. A typical type of fine grinder is the ball mill. A slightly inclined or horizontal rotating cylinder is partially filled with balls usually stone or metal which grind material to the necessary fineness by friction and impact with the tumbling balls. Ball mills normally operate with an approximate ball charge of 30 .
