The cables after cutting them off from various types of equipment can be processed by cable granulators. The material, when inserted in the machine hopper,
goes inside. After initial grinding, it is transferred by means of a suction system to
a turbine mill, which had a material for fine granulator. Separation is carried out by
gravity. The resulting dust is sucked into the filtering tube. The basic technical
parameters of the cable granulator are shown in Table 2.8 (IRS 2018).
2.5 Case Study: Configuration of Small and Large
Appliances Processing Line
Large home appliances disassembly starts with manual operations discussed in the
previous section. Small home appliances potential scrap material value per piece is
low. The cost of labor is too high in developed countries for conducting manual
disassembly. Therefore, opening the casing of any small appliance should be processed mechanically for subsequent removal of any components containing hazardous substances. Figure 2.6 shows a different approach in a configuration of
processing large home appliances and small home appliances. Cooling appliances
and television sets are excluded from processing in this configuration. The processing line consists of two subordinate lines, A and B, which are connected at point C
shown in Fig. 2.6. Large home appliances excluding cooling equipment manual
disassembly are conducted at the station – 1 supplied by forklifts. Then the casings
