are transferred to the shredder – 2. Line B is for processing small home appliances.
It can be loaded by a bucket loader or a handling machine equipped with hydraulic
grip inside a hopper – 3. A shredder – 4 is equipped with large wide teeth. The intention is to shred small equipment in a larger piece of materials to allow manual separation of components containing hazardous substances or homogeneous material
parts at the station – 5. Both lines connect at point C. A cyclone separator – 6 is for
removing dust or any light objects from further treatment. Further process includes
magnetic separation – 7, eddy current separation – 8, and transfer of nonferrous
metals and alloys to a hammer mill – 9. The final stage of separation is conducted
on screening separator – 10 (size of grains) and gravity separators – 11 (light and
heavy metal fraction). The line productivity can be adjusted by changing the number of manual disassembly stations accompanied by the increased capacity of individual processing machines.
2.6 Conclusions
A big variety of groups and types of waste equipment require preselection of the
equipment similar in disassembling sequence. The findings of this study show that
it is necessary to reduce a number and types of specialized shredding and sorting
machines applied to disassembly lines. A modularity of a recycling plant by selection of autonomous units linked together to form a processing line would benefit in
lower costs and the size of a plant. The concept of a reconfigurable recycling system
of E-waste presented in this research assumes modularity of the disassembly line
