Plant engineering and processing technology for waste wood and bulky waste
Wood is becoming an increasingly sought-after raw material that needs to be separated from other types of waste. Around 8 million tons of waste wood are produced every year. The material comes from packaging, construction and demolition timber, wood waste from industry and bulky waste and is processed for material or thermal recycling.
Waste wood is divided into 4 classes depending on its contamination:
- A1 untreated wood, only mechanically processed
- A2 glued, painted, coated wood without wood preservative
- A3 waste wood with halogen-organic coating and wood preservative
- A4 wood treated with wood preservatives such as railroad sleepers, utility poles, etc.
Classes A1 and A2 are mainly recycled, e.g. for the production of chipboard; on average, this amounts to around 2.4 million tons per year. Classes A3 and A4 are mostly used for energy generation in biomass power plants.
Our SPLITTER offers you safe and optimal pre-separation and processing of waste wood, bulky waste, green waste and root wood for all subsequent processes. Our SPLITTER turns waste wood into marketable material quickly and efficiently.
SPLITTER in the application waste wood and bulky waste
The actors
- Companies as suppliers for biomass power plants
- Service providers
- Wood processing industry
- Energy suppliers
The challenge
- Impurities lead to high wear and energy costs on the secondary shredder
- Increasing need to separate wood from other types of waste (e.g. bulky waste, demolition waste and screen overflows from composting)
- Maximum throughput with consistent screen quality
Recycling of shredded waste wood
The SPLITTER HOOK screens the fines smaller than 100 mm from the shredded waste wood. The oversized particles are then fed back into the shredding process so that the fine fraction predominates at the end. This can then be processed further.
Feed material: Pre-shredded waste wood
Target: a screening of <100 mm for biomass.
Target material: Biomass with a grain size of <100 mm
MULTISORT treatment plant
The plant was built in 2020. It processes 30-33 tons of waste wood per hour. The plant uses a pre- and post-shredder, FE and NF separation, an air separator, conveyor technology including reversing belts and a MULTISTAR 2-SE star screen.
The system was also supplied by GÜNTHER including the control technology, into which the shredding technology was integrated. This is located in a specially designed container.
The SPLITTER as a solution
- Reliable separation of impurities
- Reduction of wear and energy costs on the secondary shredder
- Problem-free processing of difficult input material and impurities
- Optimum recycling of the individual material streams
- Remove oversized material to ensure subsequent quality processing
The advantages of the SPLITTER
- Effective and cost-saving
- Wear-resistant against impurities such as FE, NE, glass and minerals
- Winding and clogging-free
- Highest throughput capacity
- Uniform material flow
- Optimum preparation for subsequent processes
- Self-cleaning effect > low-maintenance system
- Protection for downstream units
Waste wood processing with SPLITTER HOOK and TAKER HOOK as feeding unit
The SPLITTER HOOK screens the fines smaller than 100 mm from the shredded waste wood. The oversized particles are then fed back into the shredding process so that the fine fraction predominates at the end. This can then be processed further.
Feed material: Pre-shredded waste wood
Aim: to screen out excess lengths
Target material: Biomass with a grain size of <100 mm
Waste wood processing with SPLITTER HOOK and RETURNER as return unit
The SPLITTER HOOK screens the fines smaller than 100 mm from the shredded waste wood. The oversized particles are then fed back into the shredding process so that the fine fraction predominates at the end. This can then be processed further.
Feed material: Pre-shredded waste wood
Target: is a screening of <100 mm for biomass.
Target material: Biomass with a grain size of <100 mm
Separation by pre-shredder
- Processing of waste wood A1 to A4, bulky waste, green waste and root wood for biomass power plants
- FE and non-ferrous removal
- Screen cut SPLITTER 80-120 mm
- Throughput capacity of up to 50t/h
SPLITTER HOOK
The hook-lift mobile SPLITTER HOOK achieves the highest possible screening capacity on the smallest possible screening surface. It is suitable for different types of waste such as domestic and commercial waste, waste wood, organic waste and other types of waste.
RETURNER
The RETURNER return unit is the ideal complement to the SPLITTER HOOK. It is always used when only the undersize particles are required for separation, e.g. waste wood: Waste wood. The RETURNER can also be used as a feeding unit.
SPLITTER UNIT
With its compact screen deck, the stationary SPLITTER UNIT is particularly suitable as the first step in a process chain for processing solid waste such as commercial and household waste, scrap metal, slag, waste wood and much more.
