Sepor's batch ball and rod mills are designed to give size reduction of laboratory quantities of minerals and ores. Feed size should generally be -1/8″, for ball mill and -1/2″ for rod mill. They are of a sturdy, rugged design to handle frequent use with hard materials. The batch ball and rod mills require a drive roll to rotate the mills. Oleg D. Neikov, in Handbook of Non-Ferrous Metal Powders, 2009. Tumbling Ball Mills. Tumbling ball mills or ball mills are most widely used in both wet and dry systems, in batch and continuous operations, and on a small and large scale.. Grinding elements in ball mills travel at different velocities. Therefore, collision force, direction and kinetic energy between two or more elements vary

Dec 23, 2013Rod mill is similar to ball mills but it uses long rods for grinding media. Autogenous mill is a self-grinding mill which is used in breakage of larger rocks. SAG (Semi-Autogenous Grinding) mill is an autogenous mill which uses grinding balls, it is similar to ball mill

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.

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

The Accu-Lab Jr. Laboratory Drawdown Rods. The Accu-Lab Jr. Laboratory Drawdown Rods (N008-026, N008-026A) are designed for users producing test samples up to 8 wide. These stainless steel rods are 4 shorter than conventional lab rods and offer an additional savings.

The Bond Index conforming rod charge consists of: 6 rods of 1.25" diameter and 21" length; 2 rods of 1.75" diameter and 21" length; The grinding jar for the Bond Index Rod Mill is 12″ x 24″ in size and has a wave-shaped design. At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill.

Laboratory Rod Mill. Working Principle. A rotating drum causes friction and attrition between steel rods and ore particles. But note that the term 'rod mill' is also used as a synonym for a slitting mill, which makes rods of iron or other metal. Rod mills are less common than ball mills for grinding minerals.
