Rods are loaded or charged into a Rod Mill using a mechanised charger. The rod charger with extendable boom moves rods safely inside the trommel/trunnion before charging with a typical 30 seconds or less cycle time per rod.
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).

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.
A rod charger is a device that adds a grinding medium, such as a steel rod, to a rod mill. The main purpose of this equipment is to introduce the steel rod into the rod mill. The …
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.

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 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 ...
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) …
