The PulseWave NRD Mill operates on the novel principle of resonance disintegration that reduces the particle size of various materials by the application of the physics of resonance, shock waves and vortex-generated shearing forces, as opposed to the crushing and grinding processes of conventional milling methods. The design geometry of the PulseWave NRD Mill provides for a somewhat symmetrical level of the magnitude of shock waves, and the forces are phased so that the efficiency of the process is enhanced while the energy transfer to the machine is minimized. This results in materials being fragmented from within, rather than being crushed to failure by kinetic impact grinding mills which can damage or destroy many types of materials such as high molecular weight polymers. Hence, most materials can be reduced to various small particle sizes without destroying their basic fabric or structural habit; that is, euhedral crystalline materials will tend to retain their euhedral nature when micronized by the NRD process, acicular particles will tend to retain their acicular nature, and so forth.

In addition to its ability to reduce the particle size of materials, the PulseWave NRD Mill is also capable of selective differential fragmentation of particles in complex multi-phase materials. Since different components in a heterogeneous material will have different elasticities, they will tend to resonate at differing frequencies in the NRD machine, resulting in their being separated from one another. For example, plant fiber can actually be liberated from intracellular components by the NRD process; small sections of hydraulic hose can be delaminated into separate steel wire and rubber fractions; gold particles can be liberated from mine tailings or slag; and crystalline materials are cleaved apart along the natural planes of their structure. Materials of heterogeneous composition are differentially fragmented with the harder, less elastic components being fragmented into smaller particle sizes while simultaneously liberated from softer, more elastic components. This provides the basis for "dry" fractionization. The PulseWave NRD Mill can be operated at different speeds and directions (clockwise, counterclockwise) providing versatility in particle size reduction processing.

Another benefit of the NRD process is that it generally produces a "tighter" statistical distribution of particle sizes. This results in a more uniform, consistent and predictable product. Materials can be processed in several different media including standard atmospheric air, helium, liquid nitrogen, carbon dioxide, or otherwise, which allows for the custom micronization of materials of various chemistry and volatility. The throughput of our standard-sized machine varies from 500 pounds to over 8,000 pounds per hour, based on the size and composition of the starting material, the desired ending particle size, the speed and rotation of the mill, and other factors. And finally, the PulseWave NRD process is: (a) cost effective – In most cases materials can be reduced to a particle size similar to or in some cases even smaller than conventional impact-based ball or jet mills but at a fraction of the energy demand, resulting in lower processing costs and energy savings. This cost differential is particularly evident in the finer (micronic) range, often resulting in energy costs as little as fifty percent or less than kinetic based impact mills; and, (b) efficient – material introduced into the PulseWave mill is processed in a matter of seconds! Material reduction that takes other methods minutes, hours, or days can be processed quickly in the PulseWave NRD Mill.
