A rod mill is a type of ore grinding equipment used to grind materials into fine powder. Unlike ball mills, rod mills use long steel rods instead of balls as the grinding medium.Rod mills are ideal for breaking down materials such as minerals and ores.

The mill power is also increased by increasing the rod charge and the mill speed, while the mill power and capacity are both increased with increasing mill length. Based on these observations and working on wet overflow mills, Rowland and Kjos [2] suggested that the power draw at the pinion shaft per unit mass of rods is given by (8.6) …

We can calculate the steel charge volume of a ball or rod mill and express it as the % of the volume within the liners that is filled with grinding media. While the mill is stopped, the charge volume can be gotten by measuring the diameter inside the liners and the distance from the top of the charge to the top of the mill. The % loading or ...

The bulk density of a new or freshly culled (i.e., broken rods removed), graded rod charge is 390 lbs. per cubic foot (5.0 kg/m³) Due to lack of culling and the greater tendency for rods to break as mills increase in size, the estimated bulk density of the rod charge must be reduced accordingly (Rowland, 1982).

grinding mills. Our rod mills have been manu-factured since 1925. Applications The rod mill, a tumbling mill characterized by the use of rods as grinding media, grinds ores, coal/ coke, and other materials for both wet and dry p- a plications.

The mills were initially charged with a 105-ton rod charge (32% of mill volume) in equal amounts of 2″, 3″ and 3½" rods. The mills drew 1200 hp with only rods in the mill and 1100 hp when grinding ore with 4% moisture. The feed rate varied from 50 to 70 long tons per hour with the mill product being 20% plus 20 mesh. Rod tangling ...

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 rod charge to the mill in all experiments consisted of thirteen .9 cm diameter stainless steel rods, weighing 7-94 kg. This corresponds to a 40% filling of the mill internal volume by the rods at rest. The operating speed of the mill was fixed at 79 rpm in all cases, this speed corresponding to 61.4% of the mill critical speed. ...

Rod mills in the mining industry are used for grinding ores into finer particles, preparing them for further processing. They operate by using steel rods as the grinding media, which tumble and crush the ore through impact and abrasion. Rod mills are particularly effective for coarse grinding and produce a uniform particle size distribution ...

The rod charge must be maintained in good working condition, and broken and worn rods must be removed. Rod mills usually require greater operator attention. It is important that the rods stay essentially parallel to one another. If rods become misaligned, grinding action is lost and, more importantly, rod tangles occur. Maximum rod length is ...

Rod Mills are particularly useful, if you run a low tonnage operation and are looking for coarse product. Our Rod Mills are available in multiple diameters to fit the needs of your operation. Grinding, primarily by attrition, Rod Mills require comparatively low levels of power to operate. Rod Mills can be either wet or dry designs.
