Theoperating principleof the ball millconsists of following steps. In a continuously operatingball mill, feed material fed through the central hole one of the caps into the drum and moves therealong, being exposed bygrinding media. The materialgrindingoccurs during impact fallinggrindingballs and abrasion the particles between the balls.
Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be3 to 4in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.

The CRRK series of wet grinding rod mills are tabulated below. The grinding charge in a ball mill consist of cast or forged steel balls. These balls are fed together with the feed and consequently ball mills can be in operation for months without stopping. The ball size is often in the diameter rangeof 20-75 mm.

TheMediaTheball millconsists of themillbase and themilljar. There's one more important component toa ball mill, though: themedia. The balls of heavy material which fall upon and crush the chemicals are called the millingmedia. Here's themediaI bought to use in thismill.
A ball mill, a type of grinder, is a cylindrical device used ingrinding(or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ballmills rotate around a horizontal axis, partially filled with the material to be ground plus thegrindingmedium. Different materials are used asmedia, including ceramic balls, flint pebbles and stainless steel balls.
Depending on the height of the material bed, thegrinding media insidetheBall Millcauses a characteristic noise. In case of high material bed (max. fillinglevel), there is hollowgrindingsound (low volume & lowgrindingfrequency), where as for low material bed (min. fillinglevel), there is high pitched sound (high volume & highgrinding...
