Ball mills are different. The grinding media is unfixed steel ball, etc., which produces larger sized powder than grinding mill. the size of the discharged product can mainly be adjusted between 40-250 mesh. If the size of discharged product is uneven, it is needed to equip a powder separating machine.

The Hardinge Mill is adapted to the complete finishing of limestone mixtures, coal and cement clinker, in one operation. To accomplish this with a good output, it is advisable to crush the feed to 3/4″, or preferably 1/2″ in size. This will allow the use of balls ranging from about 1 1/2″ in diameter to 3/4″, and will give a large ...

For an extremely basic answer, an end mill is rotated in the spindle of a milling machine and moved against a piece of material (metal or otherwise) and the rotating 'blades' on the edge of the tool will slice away material to produce the desired form or shape. Originally an end mill was used to remove material using only the cutting flutes ...

The size reduction is achieved by the impact of the balls on the particles as well as by the attrition between the balls. The mill uses a combination of both impact and attrition forces to achieve the desired particle size. Construction of Ball Mill. A ball mill typically consists of a cylindrical drum partially filled with balls, typically ...

For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.
