Rod mills are particularly useful if you run a low tonnage operation and are looking for coarse product our rod mills are available in multiple diameters to fit the needs of your operation grinding primarily by attrition rod mills require comparatively low levels of power to operate
Grinding medium of rod mill the rod of diameter from 50 to 100 mm is often used as the grinding medium and the filling rate of rod mill is 35 to 45 while filling rate of ball mill is 40 to 50 rod is mainly made of several materials a high carbon steel
Very large tonnages can be ground with these ball mills because they are very effective material handling devices ball mills are rated by power rather than capacity today the largest ball mill in operation is 853 m diameter and 1341 m long with a corresponding motor power of 22 mw toromocho private communications
In coarse grinding when the product size is 13mm the processing capacity of the rod mill is greater than that of the ball millusually the feed size of rod mill is 1523mm in fine grinding when the product size is 05mm the grinding effect of the ball mill is greater than that of the rod millthe feeding particle size of ball mill is generally 525 mm

On the other hand the surface area of the steel rod medium in the rod mill is smaller than that of the steel ball medium in the ball mill so the utilization factor is lower than that of the ball mill of the same processing capacity rod mills are often used in coarse grinding operations and are not suitable for fine crushing buti in some cases the rod mill can replace the fine crusher and solve the problem that the
When the mill is rotated without feed or with very fine feed the rods are in parallel alignment and in contact with one another for their full length new feed entering at one end of the mill causes the rod charge to spread at that end this produces a series of wedge shaped slots tapering toward the discharge end the tumbling and rolling rods expend most of their crushing force on the
May 08 2020 ball mill machine has always been the main grinding equipment in wet cement production in the early years the rod mill was first used in cement raw meal grinding which increased the output of the grinding section by 31 saved energy
Rod 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 in the two stage grinding process if it requires grinding the ore from 206mm to 13mm in the first stage rod

Apr 09 2015 ball mills ball mill fig 1 is same kind of mill as rod mill except that it is filled with balls instead of rods because of balls have greater ratio of surface area than rods they are more suitable for fine grinding balls are also lighter so the kinetic energy of a single dropping ball is smaller than a rod
May 08 2020 usually the charge ratio of the ball mill is 4050 and that of rod mill is 3545 ball mill vs rod millprocessing property the ball mill machine has the high grinding production capacity and strong adaptability to materials the fineness of the ground product is high and the output size is fine
The processing capacity of rod mill is greater than that of the ball mill when the product size is 13mm in the coarse grinding process while the grinding effect of ball mill is greater than that of the rod mill when the product size is less than 05mm in the fine grinding process
Rod mill when the particle size of the product is 13mm the processing capacity of the rod mill is greater than that of a ball mill of the same specification ball mill when the particle size of the product is less than 05mm the grinding effect of the ball mill is greater than that of a rod mill of the same specification
In addition with same specificationthe the cylinder rotating speed of the rod mill is lower than that of the ball millthe rod mill usually uses 50100mm diameter steel rod as grinding medium while the ball mill uses steel ball as grinding medium area is small too but there are still great differences in the interior both of them are horizontal cylindrical structures
3 when the rod mill is used for primary grinding the product particle sizes are 31mm the production capacity of rod mill is larger than that of the ball mill with the same specifications while the rod mill is used for fine grinding the ground and crushed particle sizes are 05mm
Apr 09 2015 ball mills ball mill fig 1 is same kind of mill as rod mill except that it is filled with balls instead of rods because of balls have greater ratio of surface area than rods they are more suitable for fine grinding balls are also lighter so the kinetic energy of a single dropping ball is smaller than a rod
The ball mill is a tumbling mill that uses steel balls as the grinding media the length of the cylindrical shell is usually 115 times the shell diameter figure 811the feed can be dry with less than 3 moisture to minimize ball coating or slurry containing 2040 water by weight
a total apparent volumetric charge filling including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls expressed as a percentage of the net internal mill volume inside liners b overflow discharge mills operating at low ball fillings slurry may accumulate on top of the ball charge causing the total charge filling level to

Ball mills and rod mills are both excellent mining machines for grinding ores into fine powders and particles however there are some advantages to using rod mills rather than ball mills for larger mining projects including greater efficiency better grinding performance and lower energy costs
05 to 50 tph industrial rod mills a rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill
