Jul 01, 2003 every mill is limited in cooling surface area and therefore limited to the maximum amount of energy that can be used for grinding. this dictates the installed motor power for a mill. the nominal energy density of a mill is the available energy per volume of milling chamber. energy density installed motor power kw mill chamber volume liters
The rotation is usually between 4 to 20 revolutions per minute, depending upon the diameter of the ball mill machine. the larger the diameter is, the slower the rotation is. if the peripheral speed of the ball grinding mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill.
Ball mill is an efficient machine for fine powder grinding and key equipment for grinding after the crushing process. there are two ways of ball mill grinding the dry way and the wet way. it is used to grind many kinds of mineral ores and other materials, or to select mine.
