The main difference between a rod mill and a ball mill is the grinding medium. Rod mills use long steel rods as the grinding medium, while ball mills use steel balls. Additionally, rod mills are better suited to handling larger feed sizes, and they create a more uniform particle size distribution than ball mills.

Ball mills and rod mills are two types of grinding mills that are often used for this purpose. Both types of mills have their advantages and disadvantages, and the choice between the two depends on several factors. Ball Mills: Ball mills are cylindrical devices used to grind materials such as chemicals, ores, and paints.The cylinder is filled with a grinding …

Ball and Rod Mills. Jean-Paul Duroudier, in Size Reduction of Divided Solids, 2016. 3.7.4 Performance. 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.

Rod mills are used for grinding hard minerals. This type of mill is usually used as the first stage of a milling process to provide a reduced size feedstock for a further milling process.

 — The mill will produce 8, 12.7, 15.6, and 19 millimeter-diameter rods. This is the fifth rod mill supplied by Primetals Technologies to Southwire for their wire and cable business. The company had previously ordered one copper rod mill and three aluminum rod mills from Primetals Technologies' predecessor, Morgan Construction.

 — Commentary on the apparatus of the Bond rod mill Work Index. by Alex Doll December, 2015 [email protected]. The Bond "Third Theory" of comminution was originally divided into three size …

 — The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.

 — Center Periphery Discharging Rod Mill. The center periphery discharging rod mill feeds the material through the journals at both ends of the mill, and discharges the grinding products through the circular orifice in the middle of the cylinder (Fig. 3).Ore pulp is characterized by short stroke, steep slope, and it can be coarsely ground with fewer fine …

A. as a rod, ball, or pebble mill. B. in open or closed circuit with cyclone or spiral classifier. C. as a wet or dry mill. D. as an overflow, grate, or peripheral discharge mill. E. available in various lengths as shown in table. F. in a variable speed range of approximately 67% to 80% of critical speed.

Both ball mills and rod mills play important roles in grinding materials, but there are multiple significant differences between them. In this article, the similarities and differences between ball mills and rod mills are analyzed from 9 aspects, and suggest how to …

Ball Mills. Ball mills have been the primary piece of machinery in traditional hard rock grinding circuits for 100+ years. They are proven workhorses, with discharge mesh sizes from ~40M to <200M. Use of a ball mill is the best choice when long term, stationary milling is justified by an operation.

1. Used as the primary comminution unit in a grinding circuit.
2. Rods are placed parallel along the length of the rod mill.
3. Rods are 150mm shorter than the mill length.
4. Breakage occurs more from cascading than cateracting.

Applications of AG Mills in Mining.

 — For a given rotating speed and filling of the mill, impact velocities of balls and the nature of forces developed inside the mill can be controlled by the most favorable configuration of lifter bars. The action of lifter bars is best understood by following the motion of ball charge inside the mill.

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 …
