Construction, demolition and bulky household waste
The purpose of the installation is to separate hard plastics, foils, metal, paper, stone and wood from construction, demolition and bulky household waste. Wood, plastic and foils are the largest and most valuable streams.
This installation functions essentially the same as the plant for household waste, only with coarser flows. The reduction of fractions requires more attention and sensitivity to wear. Ideally, it should be implemented in a recycling plant with as few bends as possible. At transfer points, wear plates are placed with 400 to 500 Hardox.
The installation is based around the separator for construction, demolition and bulky household waste from a shredder, sieves, magnets, wind shifters, ballistic separators and Near Infrared (NIR) scanners.
The material is separated into a 2D and a 3D stream. The 2D stream consists of materials such as foils, paper and textiles. The 3D stream includes form-retaining materials such as hard plastics.
From the 2D stream, paper and foils are separated by means of wind shifting. From the 3D stream, hard plastics are separated with the aid of NIR-scanners. Where necessary, these streams are culled via magnets to remove iron or non-ferrous metal and cans. An NIR scanner sorts plastics into streams for PET, PP and PE. Wood and stone can be based on specific weight, or separated using radiation techniques.
The separation plant for construction, demolition and bulky household waste can be customized, designed and implemented with a processing capacity of 10 tons / hour to 70 tons / hour.
