Rock ball mill ball mill rod mill,Our company is a large-scale heavy enterprise that taking heavy mining machinery manufactory as main products and integrated with scientific research, production, and marketing. We are concentrating on producing and selling machines such as jaw crusher, cone crusher, hammer crusher, ball mill, sand maker, mobile crushing plant
The mill product can either be finished size ready for processing or an intermediate size ready for final grinding in a rod mill ball mill or pebble mill agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening a rod mill and some or all of the work of a ball mill
Chat OnlineBall mills are a similar shape to that of the rod mills except that they are shorter with length to diameter ratios of 1 to 15 as the name implies the grinding media in these mills are steel balls the particles size of the feed usually does not exceed 25 cm

Chat OnlineAt least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill the rod mill work index rwi is used for particle size determination in a size range from 25 mm down to 21 mm whereas ball mill work index bwi is used for the range from 21 mm down to 100 m adjustment of grinding parameters
Chat OnlineBallrod mill literature the ballrod mills are meant for producing fine particle size reduction through attrition and compressive forces at the grain size level they are the most effective laboratory mills for batch wise rapid grinding of medium hard to very hard samples down to finest particle sizes more
Chat OnlineRod mill is a type of grinding mill whose grinding media is steel bar while ball mill is steel ball 1 rod mill are usually applied to grinding the wsn ore and rare metal in the reselection or magneticoredressing plant in order to avoid the damage caused by the over crushing 2
Chat OnlineBall mills and rod mills are grinding equipment widely used in concentrators the two have similarities in shape and grinding principles but there are differences in structure performance and use this article analyzes their similarities and differences from seven aspects and tells you how to choose ball mill and rod mill
Chat OnlineRod mills are grinding machine which employ high carbon steel or special steel rods of nearly the same length as that of the drum in place of steel balls in ball mills rod mill products are generally coarser than those produced in a ball mill and rod mills are well suited to handle coarser feed and to control the top size of the product

Chat OnlineWhen calculating rod mill power for a rod millball mill circuit do not allow for improvement in the ball mill performance due to receiving rod mill feed if the rod mill feed is produced with open circuit crushing apply a 12 inefficiency factor to the power calculated for the rod milling stage only
Chat OnlineRod mills are very similar to ball mills except they use long rods for grinding media the rods grind the ore by tumbling within the the mill similar to the grinding balls in a ball mill to prevent the conditions leading to rod charge tangling the length to diameter ratio is maintained at 14 to 16
Chat OnlineBall mill a typical type of fine grinder is the ball milla slightly inclined or horizontal rotating cylinder is partially filled with balls usually stone or metal which grind material to the necessary fineness by friction and impact with the tumbling balls ball mills normally operate with an approximate ball charge of 30
