Waste as a raw material is not homogeneous, which is why every line is engineered according to what exactly comes in and what is required at the outlet. Vecoplan AG supplies the equipment for size reduction, and Amandus Kahl for pelleting and granulation.
A different technical solution is engineered for each type of input material. The aim is always a defined final product with the appropriate characteristics.
Pulpwood and firewood, sawmill residue, pallets, wooden crates, offcuts of MDF and OSB boards and chipboard, waste from joinery and parquet workshops.
Municipal, urban, industrial and other waste, with separation of inert matter and preparation for alternative fuel.
Newspapers and print, reel paper, folders, CDs. The screens allow separation into up to four fractions over an area of up to 9 m².
Bags, pipes of various dimensions, boxes, films, nets, mouldings. Plastic is a valuable raw material once it is properly prepared.
Granulation by ambient grinding, without nitrogen, granulate 0.1–8 mm, free of metal and textile.
Pelleting of sewage and industrial sludge, and processing of compost into NPK-enriched fertiliser.
The Kahl ambient grinding process is an alternative to the usual cryogenic process with nitrogen, saving up to €80 per tonne.
The delivered tyres are ground down to a size of 50 × 50 mm.
A press working on the mill principle reduces the pieces to ≤ 20 mm. A belt magnet removes the steel wire, and the first screening takes out the fines.
The coarse fraction goes to a second size reduction, where the material is brought down to 0.1–8 mm.
A three-stage process separates the fractions. Cylindrical magnets remove metal, and the final screening is done by gravity and zig-zag separators. The final product is packed in bags.
Values from plants already built. For your case they are calculated according to the input material and the required final product.
| Application | Parameter | Note |
|---|---|---|
| Tyre granulation | 4 t/h in three shifts | A plant of 20,000 t per year |
| Annual output | 1,600,000 passenger car tyres | or 150,000 truck tyres |
| Granulate size | 0.1–8 mm | Free of metal and textile |
| Saving on granulation | up to €80/t | Compared with the nitrogen process |
| Sludge, dry matter | 60–95 % | At 60 % the pellet is less hard than at 90 % |
| Sludge, bulk density | 150–200 kg/m³ | Dosing by special units ahead of the press |
| Screens for paper | up to 4 fractions | Screen area up to 9 m² |
| Pellet mills | 3–630 kW | Flat die press, 16 sizes |
Vecoplan has been building size reduction machines for four decades. Single- or twin-shaft designs, hydraulic drive, damage protection and a construction built for continuous operation. Chippers and shredders deliver a homogeneous, standardised mass, either as a fuel or as preparation for pelleting and briquetting.
The flat die press works on the mill principle: compact, robust and flexible. It is distinguished by long tool life, a long interval between two re-sharpenings and granulation with only two lines, without waste.
Flat and trough belts designed for quick and reliable cleaning, with a robust construction and low-cost maintenance. Alongside them come screw conveyors, magnetic drums, oscillating and star screens and units for separating inert matter.
Municipal and commercial waste and plastics yield pellets or fluff of high calorific value, used as an alternative fuel. Sewage sludge is pelleted into a dust-free product, usable as a roofing material or thermal insulation. Compost is processed into NPK-enriched fertiliser.
Alongside the above we also supply all conveying equipment, silos, bins, cyclones, filters, vibrating screens, electrical equipment and more.
Send us the type of input material, the required capacity and the desired final product, and we will come back with a proposed solution within 24 hours.
