In the ever-increasing quest for reduced mineral processing costs and increased throughput tonnages, there has been a worldwide move towards larger and larger mill sizes.As such, flsmidth has supplied some of the worlds largest horisontal grinding mills with ball mills up to 28ft in diameter 22mw and sag mills up to 40ft in diameter 28 mw.
A ball mill is a type of device that is used for grinding and turning the material into very fine powder.They are cylindrical and they are mostly used in mashing paints, ceramic materials, ores and hard chemicals.The ball mill is rotated on an axis that is horizontal and this is how it is able to convert the material into very loose powder.
We discuss the types of ball mill, the basic principles of the ball mill, how it works, the details of design including equations for optimum dimensions in all cases, some manufacturers for the ball mill, and estimation of the cost the ball mill.Introduction ball mill is an efficient tool for grinding many materials into fine powder.
The cooling of cement is an important step prior to storage in mitigating gypsum dehydration and subsequent moisture liberation which can lead to lump formation.Recommendations vary but it is generally accepted that with mill outlet temperatures of around 110c 120c, cooling to below 80c is necessary to avoid this reaction.
