General machine practice is to use a depth of cut up to five times the rate of feed such as rough cutting stainless steel using a feed of 0020 inch per revolution and a depth of cut of 0100 inch which would reduce the diameter by 0200 inch
Get Details3611 ball milling a 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
Get DetailsIn order to reduce the power consumption of the ball mill machine the feed size can be reduced therefore the particle size of the crushing product is required to be small that is more crushing and less grinding 3 control the filling rate of steel ball
Get DetailsBall mills are employed in the comminution stage as grinding machines size reduction the purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock ball mills are the most common grinding machine employed in the mining industry
Get DetailsTherefore the rpm for a l2inchdiameter end mill machining aluminum revolves at 2400 rpm and the feed rate should be 24 inches per minute the formula used to find workfeed in millimeters per minute is the same as the formula used to find the feed in ipm except that mmmin is substituted for ipm
Get DetailsThe calculation shows that the crushing ratio can reach 3000 4000 while the ball mills crushing ratio is smaller the feed size is usually between 2030mm and the product size is 03mm feed both the autogenous grinding mill and the ball mill feed parts are welded with groove and embedded inner wearresistant lining plate

Get DetailsBall mill output feed size fig 5 shows the variation of size class 1 m1 with the milling time for the two feed size distributions for this coarser feed the 50 2010 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches the availability of a ball size for a particular feed size ensures breakage occurs at a faster rate
Get DetailsJan 11 2020 jaw crusher is used to work with ball mill to reduce the feed size but it is not that the thinner the better the toosmall material size will reduce the efficient grinding generally the feeding size is controlled between 25 and 15mm the feed size is affected by the ball mill diameter feed
Get DetailsFor efficient operation of ball mills necessary to observe the right balance between balls size and feed material size if the feed material contains many large lumps and grinding balls cant crush them it leads to a gradual accumulation them between the balls as a result mill suspends own operation in these cases need to reduce the size
Get DetailsBall mills scale up well and in fact improve in performed with increasing size ball mills are available in sizes from laboratory scale also called milling jars of 01 usg to large 5000 gallon mills ball mills are available in various contact materials to accommodate contamination and wear requirements
