mill rod mill material flow

steel - steel - Billets, bars, and rods: Billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. One method of rolling billets, which are usually 75 to 125 millimetres square, is to use a three-high mill with box passes, as shown in A in the figure.

Spiral Flow Jet Mill Spiral flow jet mills are a type of microniser suitable for grinding hard and soft materials up to a hardness of 10 Mohs and producing powders from 1 to 20 microns. Material is fed into a high-speed vortex within the shallow grinding chamber which is created by introducing compressed gas through a series of specialist nozzles.

Effects of flow rate slurry solid content and feed size

ABSTRACT In this paper the effects of flow rate, slurry solid content, and feed size distribution on the rod mill efficiency have been investigated. It is difficult to achieve highest grinding efficiency without sufficient information on operating parameters and their effects on the system. Several experiments were performed on a continuous rod milling circuit. Two flowsheets arrangements were ...

Jan 25, 2012 As a result of this latter effect, the mean residence time in the rod mill is longer than that in the ball mill. The narrow size distribution of the rod mill product may be partly attributed to the plug flow mode of material transport in the rod mill in addition to the well known bridging action of the rods.

May 31, 2016 Continuous movement of the pulp through the rod mass eliminates the possibility of short circuiting any material. The discharge end of the Rod Mill is virtually open and larger in diameter than the feed end, providing a steep gradient of material flow through the mill. This is described in more detail on pages 20 and 21.

The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).
