With an ability to dry, grind and classify within a single unit gives the vertical roller mill a decided advantage over a ball mill, despite these benefits, applications of the vertical roller mill for cement grinding are less twocompartment ball mill operating in a closed circuit with a high efficiency separator.
The bonds standard ball mill is used to determine the work index value of differ ent bond work index is defined as the kilowatthours per short ton required to break from infinite size to a product size of 80 passing 100 the breakage characteristics of a material remain constant over all size ranges, the calcul ated work.
Ballrod mill literature the ballrod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size are the most effective laboratory mills for batchwise, rapid grinding of mediumhard to very hard samples down to finest particle sizes.
Working into the mill through one or both bearing trunnions, the material is ground by impact and friction from the ground product is discharged from the mill through discharge slots provided in the mill tube, through a discharge wall or through the end trunnion.
A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal balls which could be of different diameter occupy 30 50 of the mill volume and its size depends on the feed and mill size.
Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial the initial chargin of a mill, coghill and devaney 1937 defined the ball size as a function of the top size of the feed,, dv kf db ball size cm f feed size cm.

Ball mill is mainly used for grinding in mining metallic minerals and nonmetallic minerals, cement, refractories, chemical, power plant, aluminum,building material, glass, ceramic, steel slag and fly ash, follows more crushing and less grinding principle to save feed size to ball mill shall be smaller than 25mm, the output size can be adjusted by revising steel balls ratio.
The alpine so super orion bill mill is a durable milling device known for its low energy consumption and high level of paired with a hosokawa air classifier, the alpine so ball mill is capable of grinding many hard materials down to d80 2 m.
If the rate of feed increased, coarser product will be obtained and if speed of rotation is increased the fineness for a given capacity is grinding, the balls themselves wear and are continuously replaced by new ones so that mill contains balls of various mill produces 1 to 50 tonhr of powder and energy requirement.
The design of a ball mill can vary significantly depending on the size, the equipment used to load the starting material feeders, and the system grinding process can also take place in dry or wet mass of feed in size class 1 is distributed in the lower size certain.
