Differences between ball mill and rod mill Different in performance Ball mill It can be divided into two types of ball mills according to the discharging ways, overflow discharge ball mill, and grate discharge ball mill. Fote ball mill Grate discharge ball mill.
MoreThe 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.
MoreWhen 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
MoreGenerally, the filling rate of ball mill is 40% 50%, and that of rod mill is 35% 45%. 5. Fineness of Product. The discharging fineness of the material milled by ball mill is between 0.074-0.4mm, and that of the material milled by rod mill is between 0.833-0.147mm. 6. Running Cost
MoreThe difference on grinding medium is the main difference between the ball mill and rod mill. There is point-to-point contact between the ball mill with the steel ball, while there is line-to-line between the rod mill and steel rod. So, the working characteristics of the ball mill and rod mill are different. 4. Medium charge ratio of ball mill
MoreRod mills commonly use steel rods with a diameter of 50-100mm as the grinding medium, while ball mills use steel balls as the grinding medium. The difference in the grinding body is the main difference between the two.
MoreThe difference on grinding medium is the main difference between the ball mill and rod mill.

So, the working characteristics of the ball mill and rod mill are different. 4. Medium charge ratio of ball mill
MoreThe mill can be divided into ball mill and rod mill according to different purposes. 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.
MoreNow we will analyze the 7 major differences between Ball mill and Rod mill and tell you how to choose a ball mill and a rod mill. Although ball grinding mill and Rod mill work on a similar principle, they are still some big difference of each other. 1. Different form and structure. The cylinder shape proportions of two devices are different.
MoreDifference : Ball mill and rod mill is mainly for grinding grain size of not more than 60mm of various hardness ores and other materials. The resulting product after ball mill grinding, its range of variation for a particle size is below 1.5mm and 1.5mm. And as for the products grinding by rod mill, its range of variation for a particle size is
More1. Ball mill and rod mill are used to deal with various hardness of ore, rock and other materials whose particle size is not more than 60mm. The particle size range is 1.5mm and 1.5mm after treated with ball mill, otherwise, the particle size range is below 6mm and 6mm after treated with rod mill. 2. Ball mill and rod mill are distinguished
MoreRod mill and ball mill may be only one word difference in the name, but in fact, there was a striking internal differences. Rod mill,as the name suggests, is to rely on rod bars for the material grinding,and wet overflow is a generally used material way.Rod mill is generally used as a grinding equipment in the artificial stone sand
MoreThe structure of the rod mill is quite similar to ball grinder, but there are three points of difference: 1. Rod mill uses the steel rod whose diameter is 50-100mm as grinding medium but the latter mill uses steel ball as grinding medium. The steel rod is 25-50mm shorter than the barrel and the rod is made by high-carbon steel whose steel
MoreJun 11, 2019· In the order you have listed; a ball mill can fine grind down to <400 mesh if needed, a rod mill will efficiently grind to 150/200 mesh range, and a roll mill can do a +/- 100 mesh. The ball and rod mills are similar in appearence, as a large rotating lined cylindrical tube filled with either metal balls or long rods used as the grinding medium.
MoreRod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed. Rod
MoreAttrition mill is a type of grinding mill by kinds of media to crush lump to powder-like substances. The impact can be rock on rock such as in an Autogenous Grinding (AG) mill, rock and a small ball charge (~10%), used in Semi Autogenous Grinding (SAG) mills, balls of various sizes in Ball Mills and less commonly these days, steel rods in Rod Mills.
MoreThe grinding media of ball mill is steel ball, the grinding media of rod mill is steel bar. In summary, we can see that the principle of ball mill and rod mill are the same,the structure is similar. The significant differences between the two are their grinding media and the product granularity.
MoreSep 26, 2019· We very first search to the frequent floor in between the 2: Ball mill and rod mill are all circular cylinders, address with lid on each finishes. Ball mill and rod mill are each horizontal cylindrical placed grinding machines. These are commonly drived with the induction motor or synchronous motor.
MoreRod mill. A rotating drum causes friction and attrition between steel rods and ore particles. [citation needed] But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals. The rods used in the mill, usually a high
Mored. What are the essential difference between the grinding action of the rod mill and the ball mill? What is the effect of these differences in the grinding action on the size reduction in the respective mill products? [ 4 marks]-Rod mill uses steel rods as grinding media and grinding action results from line contact of the rods on the ore particle.-The Ball mill uses steel balls as the
