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 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.

The Six Pot Barrel Mill, also known as a Swing Mill, a Ring Mill or a Stone and Disc Mill, is designed for the busy laboratory, and can accept two, three, or six grinding vessels at a time. The vessels comprise a chamber and lid, a solid steel bar (stone) and a steel ring, which oscillate with a rotary motion to grind materials from approximately 10 mm lumps down to powders finer than 50 microns.
The vessels can be supplied in Chrome Steel or Carbon Steel as standard, with Tungsten Carbide vessels being available on special order. Six 100cc grinding vessels would give an approximate 600g capacity at a time
