Calculation of Grinding Balls Surface Area and Volume

Calculation of Grinding Balls Surface Area and Volume

R- the radius of the ball. The volume of a grinding ball is determined by the formula: V=4/3*π*R 3, where: V- the volume of the ball. π – PI constant, a mathematical constant that is equal to the ratio of the circle's circumference to its diameter. 3.14 is a commonly used value for PI; R- the radius of the ball.

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles and stainless steel balls.
