Get PriceAg and sag mills are now the primary unit operation for the majority of large grinding circuits and form the basis for a variety of circuit configurations sag circuits are common in the industry based on the ability to mill a broad range of ore types in various circuit configurations with reduced numbers of unit operations and a
Get PriceRod 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
Get PriceBallrod mills based on 4 liners and capacity varying as 26 power of mill diameter on the 5 size give 20 per cent increased capacity on the 4 size 25 per cent and on the 3 size 28 per cent this fact should be carefully kept in mind when determining the capacity of a steel head ballrod mill as this unit can carry a greater
Get PriceThe tm 300 drum mill is used for the preparation of granules and powders the grinding process is performed either in dry or wet conditions the drum mill can be operated either as a ball or as a rod mill by using the corresponding module a sufficient number of balls or rods is required for an effective grinding process
Get PriceConfiguration of ball mill and rod mill the proportion of cylinder shape is different the cylinder lengthdiameter ratio of rod mill is generally 1520 while the cylinder lengthdiameter ratio of ball mill is smaller only slightly greater than 1
Get PriceThese mills may be divided into three types rod mills ball mills and autogenous mills in the first type the rod mill the ore is introduced into the mill before we get to the operating skills and theories needed to operate this machine lets go over the construction of it
Get PriceBecause of this the rod mill can effectively reduce 1 feed size to 10 mesh or finer in open circuit the voids or interstitial space within a rod load are approximately half those in a ball mill grinding load rods in place weigh approximately 400 pounds per cu ft

Get PriceRod 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

Get PriceTechnical performance and application of ball mill and rod mill authordahua1 time20181010 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
Get PriceAlthough similar in operation a rod mill is often more effective than a ball mill as it requires lower rotational speeds and less steel to achieve the same results it is however limited to maximum rod and drum lengths of approximately 20 feet 6 meters and is generally only used for wet grinding processes
Get PriceRod mill and mill are two kinds of equipment commonly used in grinding order to obtain higher grinding efficiency and effectively improve the effect of dressing it is necessary to choose the right grinding ball mills and rod mills are similar in appearance many people do not know much about their specific differences making them difficult to
