Recycling in this industry mostly means converting wood input materials into a homogeneous product, which is then normally used as a fuel for boilers.
Input material usually comes in the form of cut offs from joineries and saw mills, wooden pallets, construction waste, and similar sources. Recycling for boiler fuel can also include other organic products like straws and husks, coconut shells and fibers, EFB, etc. The final size of the product is dependent on its use and can be: large chunks to go directly into industrial boilers; medium to small size chips for household boilers; processed into briquettes; small chips or saw dust for other purposes, e.g. to make pellets, used in chip boards, or used as fillers.
As we have a large range of recycling machines to suit such applications, we are able to serve the whole industry with just the right machine, from the little joinery to the large pellet producer. Furthermore, we are able to get a final product of virtually any size, from chunks to wood dust.
For pre-breaking and rough sizing, Virtus offers a wide range of shredders from 15 kW to 320 kW drives. These shredders can handle all kind of input materials at ranges from 200 kg/h to 10 t/h. Commonly, the output chip size is about 50 mm, but also smaller sizes can be achieved. The machines are not very vulnerable to contaminations like steel wires or nails, which can be removed afterwards with cross belts magnets or magnetic head drums.
For the next step of size reduction to take the chips down to saw dust, we offer several granulators and hammermills. The granulators are usually the better choice when the pre-shred material is free of all ferrous and mineral contaminations, as they provide a precise cut and therefore a uniform output material. The machines Virtus offer for this step range from 11 kW up to 400 kW with matching outputs of 300 kg/h to 10 t/h.
If the pre-shred material has a high level of mineral contaminants, then we suggest the use of hammermills. These machines are invulnerable to abrasive particles and will help free them from the organic input materials. They are also highly effective at converting the inputs into a nice fibrous end product, which has a very good bonding ability as needed, for example, when making pellets.
To round out our supply capabilities, we have a large choice of standard and customized auxiliary products. Conveyors, separators, blowers, and cyclones enable us to offer entire turn key set ups or to complete your existing recycling lines.
