Plant engineering and processing technology for mixed construction waste
Around 230 million tons of construction waste are produced every year. Around 33% of this was recycled in 2018. The shortage of building materials makes the demand for substitute building materials particularly important. This is because quality-assured recycled building materials are high-quality building materials and not inferior waste.
The SPLITTER effortlessly processes coarsely pre-sorted mixed construction waste, bulky waste and commercial waste and separates them into virtually unmixed stone and fuel fractions that can be easily sent to landfill. It achieves a throughput of up to 50 t/h. With this speed, flexibility and efficiency, you can also rely on the SPLITTER economically.
The multi-talented SPLITTER separator for use with mixed construction and demolition waste
The actors
- Demolition company
- Construction companies
- Municipalities
- Container companies
The challenge
- The slightest impurities turn construction waste into mixed construction waste and thus increase disposal capacities at landfills
- Demanding material that is difficult to screen
- Reuse of ingredients to conserve resources
Construction waste sorting plant in practice
The aim is to completely process mixed construction waste into a virtually unmixed stone and sand fraction.
Feed material: Mixed construction waste
Installed units: TWIN WAVE splitter, conveyor technology, FE and non-ferrous separator, TWIN WAVE fine splitter and star screen
Target material: 4 fractions of different grain sizes with almost pure material, which is then available as a base material for new building materials
The SPLITTER as a solution
- Separation of a fraction with a high calorific value (e.g. packaging), which can thus be removed from the process chain and passed on to other processors
- Separation of a cubic fraction that is suitable for landfills or as a secondary building material
- Clog-free separation of the undersize fraction, in order to use it - depending on its composition - as backfill material in landfills, for example
The SPLITTER advantages
- Effective separation of the individual components from construction waste and mixed construction waste
- Enables the processing of material that is difficult to screen
- Fast and cost-saving separation
Practical example of processing stone/burning fraction and RC material
Processing of stone and fuel fraction
- Processing and conditioning coarsely preconditioned mixed construction waste to produce medium-calorific substitute fuel or a mineral residual fraction for subsequent further processing
- Throughput of up to 50 t/h
- Several SPLITTER units connected in series with different screen sections from 10 to 400 mm
Preparation of RC material
- Processing of mixed construction waste, bulky and commercial waste into secondary raw materials and fuel
- Throughput and screen cut according to customer requirements
Depending on customer requirements, the processing depth can vary from coarse pre-separation to fine processing thanks to the multi-stage use of the SPLITTER.
The individual integration of individual processing steps in the different SPLITTER fractions (e.g. FE removal, air separation) enables the processing of e.g. RC material, fuels, FE fractions and minerals into high-quality end products.
The SPLITTER advantages
- Separation of an almost unmixed stone fraction and firing fraction
- Flat installation situation
- High process reliability due to robust design
- Insensitive to impurities
- Can be retrofitted in almost all existing plants thanks to its compact size
- Optimum processing of the stone fraction for feeding to a crusher > Recycling material (RC material) as secondary raw material
- Separation of a stone-free fraction > Fuel
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 and waste wood.
SPLITTER HOOK
The hook-lift mobile SPLITTER HOOK achieves the highest possible screening capacity on the smallest possible screening surface. Thanks to its robust design, it can effectively process heavy screening material.
TAKER HOOK
The TAKER receiving feeder impresses with its large capacity and high flexibility. It conveys loose material smoothly to the downstream units - the optimum solution with high efficiency.
