UDY Cyclone Mill

The UDY Cyclone Sample Mill shown below provides rapid grinding of a wide variety of soft to medium-hard materials. It is extensively used in milling grains, feeds, forages, leaves and similar materials prior to near-infrared reflectance (NIR) measurement or chemical analysis.

Other applications include small to medium-volume milling of Pharmaceuticals, detergents, fertilizers, plas- tics, coal, wood chips, and friable materials. UDY Cyclone Sample Mills use a patented* method of grinding.

High-speed rotation of the impeller and air currents throw particles into and rolls them around the grinding ring. Particles remain in the grinding chamber until impact-shattering and abrasion make them small enough to flow out the exit with the air current. The air flow removes essentially all material and makes clean out unnecessary. The air flow also minimizes heating and therefore eliminates thermal degradation. Figure 2 below Cyclone Sample Mill -BELT DRIVE The UDY Cyclone Sample Mill is powered by a 3/4 horsepower, totally enclosed induction motor with power transfer and speed step-up to 12,600 rpm using Polyflex belts. The grinding ring has tungsten carbide abrasive particles on a steel base. Ground material is collected in 120 ml glass bottles, fabric bags, or other containers. *U.S. Patent No. 3,754,715 and several foreign patents.
