Allow me to compare: Ball mills can be of the overflow or of the grate discharge type. Overflow discharge mills are used when a product with high specific surface is wanted, without any respect to the particle size distribution curve. Overflow discharge mills give a final product in an open circuit. Grate discharge mills are used when the grinding energy shall be concentrated to the coarse
#0183;#32;The material to be ground is fed between the rollers and is nipped crushed by pressure tension, versus the crushing abrasion of the ball/rod mills. The roll mill can also be operted wet or dry. Also, in between the grinding capabilities of the ball and roll mills, there are hammer, chain, cage, impact and air mills, all capable of medium to fine grinding, depending on the feed material.
difference between ball mill and 21 roller mill What are the differences between ball mill and rod mill The ball mill and the rod mill are the same type of machine on the appearance but there are still great differences in the interior It is very necessary to select a suitable machine for the production to.

Ball mill is the key equipment when the crushed materials need to be ground. Ball mill is one of high fine grinding machines that are widely used in industrial production. Rod mill is line contact, ball mill is point contact. Rod mills uses very little space which is quite convenient compares to ball mills which require more space so that...
Rod mills, how they function
Rod 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
As such, primary ball mills should be designed with the rod mill work index, and singlestage ball mills should be with both the rod mill and ball mill indices. This is because it is common to observe a difference (sometimes significant) between the rod mill and ball mill index values for a given ore type (McKen, Verret, Williams, 2006).
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.

Grinding medium of rod mill. The rod of diameter from 50 to 100 mm is often used as the grinding medium, and the filling rate of rod mill is 35% to 45%, while filling rate of ball mill is 40% to 50%. Rod is mainly made of several materials: A High carbon steel.
Now 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.
F 80 is the mill circuit feed size in micrometers. Rod 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.
When 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
I wrote an article comparison of ball mill and rod mill, from the structure shape, capacity, material, and the like points. check here.
The rod mill usually adopts the steel bar with a diameter of 50100mm 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.
