Processing of Industrial/Construction Waste

INPUT: industrial / construction waste

OUTPUT: shredded and screened material

Industrial waste means primarily the waste similar to domestic waste, i. e. wastes that are produced in business enterprises, shops, service enterprises etc. and which can be disposed of with domestic waste (without organic fraction).

The term construction waste includes all the waste mixtures that consist of organic and mineral components. In detail, the following substances and products may be contained:

plastic, wood, paper, cardboard, metal, cables, plaster, plasterboards, roofing cardboard, insulating materials, glass, rubber, excavated material

Fluids, contaminated or polluted materials such as varnish, paint and asbestos must not be contained.

The main target is the volume reduction of the input material for a specific application.

PLANT EXAMPLE

Input material: industrial/construction waste 
Throughput: 20-40 t/h
Output: shredded and screened material
Utilization output: recycling, thermal utilization

PROCESS DESCRIPTION (example)

The input material is charged into the shredder DW 3060 by wheel loader or excavator. During this step, a first pre-sorting is carried out and large contaminants such as metal and rocks can be sorted out.

The DW 3060 can be equipped with an optional comb extension, which ensures a consistant shredding. After the shredding, iron parts are separated by means of an overband magnet.

According to the application, the material can finally be screened to the desired grain size by means of the screen SM 518 or SM 620.

An optional Fe-separator can be installed above the coarse fraction discharge. In order to separate light parts from the material flow, an optional windsifter can be used.

If necessary, the coarse fraction can be transferred to a manual sorting station to carry out a further separation.
