Rod mills are limited in size to 2000 kW because the longest commercial grinding rod available is 6 m long. For this reason ... low as 10 kWh/t and a reduction ratio as high as 30. Actual cases are, the initial nine 18 ft ID × 21 ft EGL overfl ow ball mills installed at Bougainville in 1969. An unpublished
A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

The mill diameter, low or high ratio of reduction, and oversize feed factors also must be applied to the calculated grinding power. When calculating rod mill power for a rod millball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed.
Calculation of reduction ratio in crushing [image: (13553)] Crushing Equipment The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant ( blasting pattern and mining method) and others which are downstream of the crushing plant ( mill and grinding circuit selection).
The rolling mill is equipped with a walking beam furnace with a capacity of 125 tons per hour. Blooms are descaled after exiting the furnace, and then proceed through a five stand roughing mill, a six stand intermediate mill, and an eight stand finishing mill. Dimensional control is maintained by optical laser gauges and manual micrometer checks.
The reduction ratio, R, in rod mills varies from 2 and 20 depending on the characteristics of the usual reduction ratio is about 8. According to Bond [4], the reduction ratio is a function of length and diameter of the mill. The optimum reduction ratio, R RO, can be written as
