Similar appearence and working principle of ball mill and rod mill
The working principle of ball mill and rodmill machine is similar too. That is the cylinder drives the movement of the grindingmedium lifting the grinding medium to a certain height then dropping. Underthe action of centrifugal force and friction the material is impacted and groundto required size so as to realize the operation of mineral grinding.
BALL MILL VS ROD MILL what are the differences between the twodevices that are so similar and how to select suitable equipment Please findthe answer in this article.
It can be divided into two types of ballmills according to the discharging ways overflow discharge ball mill and gratedischarge ball mill.
Grate discharge ball mill can dischargematerial through sieve plate with the advantage of the low height of the dischargeport which can make the material pass quickly so tha t to avoid over-grinding ofmaterial. Under the same condition it has a higher capacity and can save more energy than other types of mills
It is better to choose a grate dischargeball mill when the required discharge size is in the range of 0.2 to 0.3 mm. Gratedischarge ball mill is usually applied in the first grinding systembecause it can discharge the qualified product immediately.
Overflow discharge ball mill is designedwith no sieve plate so that the ore pulp can be discharged directly without filtration.It is very simple in structure and convenient in maintenance.
Overflow discharge ball mill can grind oresinto the size under 0.2 mm so it is very suitable for the second grinding system. The capacity of it is about 15 lower than grate dischargeball mill in the same specification and the loaded grinding medium is alsoless than that one.

difference between ball mill and tube mill. Difference Between a Rod Mill and Ball Mill. Rod Mills has a very define and narrow discharge product size range. Feeding a Rod Mill finer rocks will greatly impact its tonnage while not significantly affect its discharge product sizes. The 3.5quot diameter rod of a mill can only grind so fine.
Therefore wire rod mill is the rolling mill with the largest number of stands and the finest division of labor in the hot rolled section. At present the modern continuous wire rod mill is generally composed of 21 to 28 rolling mills which are divided into roughing mill intermediate mill and finishing mill.
According to the grinding mechanism the grinding media steel ball or steel rod in the cylinder is lifted to a certain height with the cylinder rotation under the effect of friction force and centrifugal force then falls down with a certain line speed which has a grinding impact on the materials.nbsp
Although they have the similar working principle there are many differences between ball mill and rod mill on details.
The proportion of cylinder shape is different. The cylinder length-diameter ratio of rod mill is generally 1.5-2.0 while the cylinder length-diameter ratio of ball mill is smaller only slightly greater than 1.
In addition the cylinder speed of the rod mill is lower than that of the ball mill so the grinding medium works in the cascading 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.
The rod mill usually adopts the steel bar with a diameter of 50-100mm as the grinding medium while the ball mill often uses steel ball as the grinding medium. The difference on grinding medium is the main difference between the ball mill and rod mill.
