Sales OnlineBall Mills 【Capacity】 02-90 T/H 【Advantages】Designed for long service life, minimum maintenance, can grind and homogenize mineral ores down to the nano range, a large volume of processing capacity 【Max Feeding Size】

Sales OnlineCrushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%) Pulp (crushed ore and water) fills another 15% of the drum’s volume so that the total volume of the drum is 50% charged

Sales OnlineNov 26, 2019· The feed of the ball mill contains grinding balls In order to effectively reduce the direct impact of materials on the ball mill feed bushing and improve the service life of the ball mill feed bushing, the feeding point of the groove in the feeding part of the ball mill must be as close to the side of the mill barrel as possible

Sales OnlineOct 22, 2016· The entire mill feed enters the drum via a chute or spout and an internal spiral carries the feed into the trunnion liner The drum feeder may be used in lieu of a spout feeder when headroom limits direct spouting The drum also provides a convenient method of adding grinding balls to a ball mill The drum is generally lined with Manganese Steel

Sales OnlineA ball mill is a type of grinder used to grind and blend bulk material into QDs /nanosize using different sized balls The working principle is simple; impact and attrition size reduction take place as the ball drops from near the top of a rotating hollow cylindrical shell

Sales OnlineMay 31, 2016· Rod Mills may be considered either fine crushers or coarse grinding equipment They are capable of taking as large as 2″ feed and making a product as fine as 35-48 mesh Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations

Sales OnlineBall mills give a controlled final grind and produce flotation feed of a uniform size Ball mills tumble iron or steel balls with the ore The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds The feed to ball mills (dry basis) is ,

Sales OnlineOct 19, 2016· If a spout feeder is to be used, it is generally supplied by the user, and should be mounted independently of the mill The spout should project inside the feed trunnion liner, but must not touch the liner or spiral Ball Mill FEED BOX Ordinarily the feed box for a scoop tender is designed and supplied by the user

Sales OnlineRod mills are used in an open circuit between crushing and the ball mill They often operate in wet and where the pulp contains up to 50% solid by mass This machine is equally very applicable to dry where it could take a feed that has achieved 6% moisture As such, when the product is sticky, rod mills are preferred over ball mills
