The rod mill adopts overflow type and open type discharge does not use grate type discharge The diameter of the rod mill discharge end is larger than that of the same size ball mill When the rod mill speed is lower than the working speed of the same size ball mill the medium in the rod mill is in a sloping working state
The ball mill is commonly divided into grid type ball mill and overflow type ball mill named by the different discharging structure the rod mill is divided into overflow type and open type rod mill whose diameter of hollow shaft is generally larger than that of ball mill with the same specifications
Ball mill and rod mill solutions are available here at apt providing an effective means for grinding and blending materials in preparation for mineral liberation from rock to dust apt specifies and designs the entire circuit around the mill to ensure that the target product size is achieved ava
Rod mills have an industrial yield that is less than that of a ball mill which explains the fact that balls have a much larger grinding surface than rods the power needed to operate a rod mill could exceed 30 of the power used in a ball mill when they are worn rods must not stretch but break in rather small pieces so that they can exit
Recommendation of ball mill and rod mill ball mill and rod mill are suitable for different materials 1 the daily maintenance requires constant addition of a certain amount of steel balls while the rod mill only needs to be inspected and replaced in a period of timethe product of the rod mill is rough but the particle size is uniform coarse particles and slime are less the over
Rods are placed parallel along the length of the rod mill rods are 150mm shorter than the mill length breakage occurs more from cascading than cateracting the product size distribution is narrower than a ball mill but significantly coarser most are overflow discharge type lengthtodiameter 14 to 23 mill length 7 meters rod mill
Rod mill unlike the ball mill the grinding medium in the rod mill is a steel rod so the working characteristics are significantly different from those of the ball mill since the steel balls are in point contact the steel rods are in line contact when the steel rods are sandwiched between the steel rods the coarse particles are first

Ball mills with a drum length to diameter ratio greater than 15 are referred to as tube mills ball mills may be primary or secondary grinders primary grinders are fed from crushers such as a jaw crusher secondary grinders are fed from other grinders eg a rod mill ball mills are usually either of the grate diaphragm or overflow type
These mills exist in a variety of types rod ball pebble autogenous and semiautogenous the grinding action is induced by relative motion between the particles of media the rods balls or pebbles this motion can be characterized as collision with breakage
The ball and the rod mill basically have the same concept comprising either a 12x12 jar with grinding balls or a 12x24 jar with grinding rods the jar is attached to a rotating yoke which is driven by a motor and can be placed in three different positions upwards
Rod mill is by a rotating drum causes friction and attrition between steel rods and ore particles rod mills are less common than ball mills for grinding minerals the rods used in the mill usually a highcarbon steel can vary in both the length and the diameter however the smaller the rods the larger is the total surface area and hence
Apr 09 2015nbsp018332ball 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 rod mill is generally more efficient than the ball mill due to its more effective cascading action and the greater bearing surface offered by the rods this means it can operate at lower speeds and with less grinding agents and producing less undesirable slimes byproduct
Ball mill and rod mill are the common grinding equipment applied in the grinding process they are similar in appearance and both of them are horizontal cylindrical structures their cylinders are equipped with grinding medium feeder gears and transmission device similar appearence and working principle of ball mill and rod mill
