A rod mill uses steel rods as the grinding media in tumbling mills is an efficient means to feed ball mills a product finer than could be made in a crusher but coarser than could be made in a ball mill. The principal use for rod mills, which were invented to make ball mill feed in a wet-grinding rod mill-ball mill circuit. Rod mills came into use in the United States beginning in 1900s and ...
Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill.

The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble 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.
Sep 17, 2020 Bond presents use of his breakthrough formula relating comminution circuit feed size (F80), circuit product size (P80) and the ore Work Index to industrial equipment energy usage. It covers crushing, rod and ball milling. The Bond Ball Mill Work Index remains today as the only tool used for ball mill scale-up design.
Open Circuit Rod Mill-Closed Circuit Ball Mill. This configuration has proven in the past to be a most reliable system due to the fact that rod mills are not particularly susceptible to variations in feed size. However, the necessity to procure grinding rods may limit the
Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Industrial grinding machines used in the mineral processing industries are mostly of the tumbling mill type. These mills exist in a variety of types - rod, ball, pebble autogenous and semi-autogenous. The grinding action is induced by relative motion between the
Horizontal Coarse Grinding Mill Rod Mill Product Information . Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill.get price. Mill (grinding) - Wikipedia, the free encyclopedia.
Bond Rod Mill Grindability Test. Grinding Solutions can carry out Bond Rod Mill Work Index tests to determine the energy requirements for milling ore in a rod mill. The test requires a minimum of 20kg of -12.5mm material. Closing screen sizes typically range from 4.75mm to 212µm.
Aug 17, 2018 Rod Mills — these rotating mills use rods for grinding media causing friction and attrition between steel rods and ore particles. Rod mills can accept feed up to
