It can be divided into three types of rod mills according to the discharge methods, center and side discharge rod mill, end and side discharge rod mill and shaft neck overflow discharge rod mill. Center and side discharge rod mill
AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. The process of grinding ore with ore in a rotating cylindrical mill using large pieces of ore instead of steel rods or balls. Ball Mill A steel
#0183;#32;In the order you have listed; a ball mill can fine grind down to lt;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.
Rods are 150mm shorter than the mill length. Breakage occurs more from cascading than cateracting. The product size distribution is narrower than a ball mill but significantly coarser. Most are overflow discharge type. Lengthtodiameter= to Mill length = 7 meters. Rod MillBall Mill Circuits Diagrams of mill circuits [image: (13582)]

Of the three main types of rod mill, overflow, end peripheral discharge, and center peripheral discharge only the overflow mill is in common usage. Wet grinding rod mills are normally used in the mineral processing industry.
Though mill length is limited by manufacturing constraints for the grinding rods, our Rod Mills are available in diameters from 5 feet up to 15 feet. Designs extend to
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.
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
#0183;#32;Ball mill and Rod mill is a tool used in modern mineral processing, coal chemical industry, sand making and other industries to grind ore into powder and then used in smelting industry to smelt gold, steel, etc. Coal chemical industry coal water slurry is gasified to make chemical raw materials, and sand making is used for glass or building sand.

There are three types of ball mills: horizontal, vertical and industrial. Horizontal Ball Mills. Horizontal ball mills are the most common type. The basic design is the same but the details can vary slightly. A drum, which is usually detachable, has a door that can be used to load in the material to be processed.
Rods larger than 3#189; inch (89 mm) diameter caused the size and number of broken rods to increase at Sullivan, which would not only affect power draw and mill efficiency, but also the scrap loss component of media consumption. Most operations report that grinding rods are added to the mill two or three
#0183;#32;Unlike the ball mill which utilizes a large number of hardened steel balls to impart the grinding action, the rod mill uses steel rods lying within the drum and parallel to its axis. When the drum rotates, these rods roll around inside it, thereby crushing the feed material between them.
BMThree Rods Four Drums Intellective Ball Mill is widely used in many fields and labs. Main Application Fields: This machine is widely used in metallurgy, geology, chemical industry, building material, coal, agriculture and hydroelectricity labs and widely in concentrating mill for grinding especially in diamond industry.
