The 911MPEPPGR426 is a small 300 kilo to 3.5 ton per 24 hour day capacity grinding mill acting primarily as a rod mill but can effortlessly be converted to a ball mill. Thanks to the integrated spiral classifier, it forms an easy to operate closed-circuit grinding plant. It includes a fine ore hopper, vibrating feeder and starter rod load.

This accurate scale up is different than scale up for ball mills or other stirred milling technologies. In ball mill laboratory tests 25mm balls in a small laboratory ball mill have different trajectories and interact differently with the shell lifters and ore particles than in a large production ball mill.

Sepor's 16 x 32 continuous ball or rod mill is ideal for pilot plant studies of ore grinding and processing or just regular small scale grinding requirements you may have. The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill.

tumbling mill is studied for different operating conditions in a pilot scale ball mill. The deflection of the lifter bar during every mill revolution gives rise to a characteristic signal profile that is shown to contain information on both the charge position and grinding performance.

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.
