Barrel Mill

Variously known as a Barrel Mill, a Swing-Mill, a Ring Mill or a Stone and Disc Mill, this highly efficient grinding machine comprises a steel vessel containing a solid steel bar (stone) and one or two steel rings, which oscillate with a rotary motion to grind materials from approximately 10 mm lumps down to powders finer than 50 microns.

A particular feature of the MACSALAB Barrel Mill is that the operation is dust-free and, due to its ease of cleaning, the ground product can be fully recovered.

Typical applications would include fine grinding of ore samples for spectro-analysis.

The vessels are quickly and securely clamped to the machine by means of cam-action levers and swing-arms, and the oscillating motion is imparted to the vessel by means of a specially designed out-of-balance drive mechanism with a 1.1 kW 380/525 Volt motor. The unit should preferably be positioned within the sound-proof cabinet, which also contains a motor starter and timer.

Technical Specifications:

Motor - 1 kW, 380 V, 3 Phase, 50 Hz
Weight - 400 kg
Approximate Dimensions - 1150 mm L x 750 mm W x 1850 mm H
