Fodamon engineers share the differences between ball mill and rod mill as follows 1 Appearance and structure The shape ratio of the barrels of the two mills is different The ratio of the length and diameter of the rod mill barrel is generally 1 5 2 and the inner surface of the liner on the end cover is a vertical plane There are various.
The rod mill usually uses 50 100mm diameter steel rod as grinding medium while the ball mill uses steel ball as grinding medium The length of steel rod is 25 50mm shorter than the cylinder and it is usually made of high carbon steel with carbon content of 0 8 1 the loading capacity of rod is about 35 45 of the effective volume.
Rod mill is roughly as same as the ball mill but there are three distinct differences 1 The rod mill normally uses the steel rod of 50 100mm as the medium and the ball mill uses steel ball as the medium The length of steel rod is 25 to 50mm shorter than the barrel body the load of rod quantity is 35 to 45 of the effective volume of the rod mill.
Moreover the cylinder working speed of Rod mill is lower than that of ball mill under the same specification so that the medium inside the mill is in the state of falling 2 Different ways of discharging The most frequently used ball mills are lattice ball mill and overflow ball mill they are named from their different discharge structure.
Rod 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 More Details.

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 Details.
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 the rod mill often replaces the fine crushing crusher to solve the problem of blockage of discharge.
The general ore grinding process in most overseas ore beneficiation plants is made up of crusher rod mill and ball mill The rod mill is hardly used in China ore beneficiation plant The feeding particle of ball mill is too high which causes the large consumption of energy grinding medium and lining plate.
Rod Mill And Ball Mill For Aggregate And Concrete Production The difference between ball mill and rod mill 1 Shape and structure The ratio of tube length to diameter of the rod mill is generally 1520 and the inner surface of the lining plate on the end cover is vertical plane The ratio of cylinder length to diameter of ball mill is small and in most cases the ratio is only slightly greater than 1.
Rod mill and ball mill are both used to grind ore and be chosen according to the different working condition Generally speaking different contact mode determines different grinding granularity Rod mill is applied for coarse grinding for the reason that its media is steel rod and is liner contact while ball mill is applied for fine grinding for the reason that its media is steel ball and.

Ball mills with a drum length to diameter ratio greater than 1 5 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 e g a rod mill Ball mills are usually either of the grate diaphragm or overflow type.
Recommendation of ball mill and rod mill Ball mill and rod mill are suitable for different materials 1 Selection by materials hardness Ball mill has a strong adaptation of material and it is suitable for grinding hard materials such as slag iron ore copper ore etc Rod mill is suitable for grinding brittle material such as rare metals.
Apr 24 2020018332In 1895 William of the United States invented the impact crusher with lower energy consumption At the same time grinding machines have also developed accordingly and a ball mill with a wide range of uses appeared in the early 19th century In 1870 on the basis of ball mill rod mill with uniform discharge size was developed.
Rod Mill And Ball Mill Crusher Because 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.
In addition the processing capacity of the rod mill is larger than that of the ball mill of the same specification The overflow end peripheral discharge and center peripheral discharge are the three main types of rod mill while only the wet overflow type rod mill is usually used as the pre grinding equipment in the cement plant In order to.
Jan 01 2016018332A uniform discharge from a closed circuit jaw crusher is 200 th The crusher feeds a wet rod mill such that 80 of the crusher product passes a 16 mm screen The rod mill feeds a wet ball mill at a feed size of 1 0 mm 1000 m and produces a product with 80 passing a 150 m screen The rod mill is in an open grinding circuit Determine 1.
