The VIS machine is a true breakthrough in materials processing technology. It is an aero acoustic device that uses the extreme forces in a controlled vortex to smash material particles and rip moisture from material and produce an ultra-fine dry powder.
The controlled vortex in the machine creates exceptional forces relative to what is found in typical industrial machinery:
Through using the fact that some components within a material do not respond to aero acoustic forces in the VIS machine, we have been able to create new options for recycling materials where there were only expensive energy-intensive options to break down materials to seperate components so that they could be recycled. In some cases we have now provided a solution for recycling where components in materials can be efficiently seperated where this was not possible before.
Due to the extreme forces and the patented process of applying the VIS machine forces to solid materials, the particle surface is chemically activated and material achieves a reactivity that is far past its natural state
Unlike conventional mechanical comminution plant, the VIS machine produces a jagged and ridged particle that is not smooth and round. This drastically improves the surface area of a particle, thereby also improving particle response to chemical reactions. This kind of shape if also conducive to mechanical compaction for pelleting or improving structural strength in products like concrete
The aero acoustic forces applied in the VIS machine literally explode particles apart. There are very complex forces in play to cause this effect and it means that we are able to achieve ultra fine materials processing without any direct mechanical impact or there being any residue from mechanical impact tools commonly used. Not all materials respond to these forces however, there is little impact on plastics, formed metals and paper.
Due to the unique aero acoustic forces in the VIS machine, any particle surface moisture or moisture embedded within a particle clump, is ripped out and vaporised. It is essential to manage the output material with the relevant plant to ensure that the freed moisture does not recombine onto the ultrafine particles.
The machine is supplied in a 40-foot high-container that has been reinforced with tons of soundproofing material and outfitted with safety controls and weatherproofed. The VIS machine has been engineered to operate and to be repaired in remote locations with wear and tear components that are standardized and usually fairly standard to source and stock. By implication, this also means that on-site mechanical staff can carry out maintenance repairs, as there are no specialist skills required.
This is a major productivity advantage as it means production is not unnecessarily delayed by waiting for specialist engineers to arrive for breakdowns and planned maintenance, in contrast to most high-volume plant options for materials milling and grinding.
Part of the client staff training is then related to understanding the wear and tear components and training client staff on the impellor blade replacement and basic maintenance.
The VIS machine does not have complex site requirements for operational set up. It can be run on levelled and compacted ground and is self-balancing. This means that machine can be operated on a mobile basis and can easily be moved and relocated to new sites.
The main wear component on the machine is the blades on the impeller unit as the processed and ultra-fine material passes over the blades as they exit the machine. The impeller blades have high wear material cladding and will have different wear rates for different materials.
