The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the type of circuit .
· I know the ball flies, and it can be really tricky." Altitude is not the only component in deciding which type of tennis ball is better suited for competition. Temperature plays a large role as well. According to Wilson, the only time you would not use a highaltitude ball at elevation is if the temperature were to drop to the mid40s or lower.
Crosssection of end mill A tool rotates clockwise is called "Right cutting edge". A tool rotates counterclockwise is called "Left cutting edge". Ordinary end mills are "Right cutting edge" and "Left cutting edge" are very rare. Clockwise Counterclockwise Direction of rotation Direction of rotation

Ball mills m (18 ft) in diameter and larger tend to use energy delivered to the mill less efficiently than smaller diameter mills, particularly when the large mills carry 40% by volume ball charges. This paper will explore factors used in scaling up ball mills, showing where the advantages of one factor can possibly be negated by another factor.
