2. Description of the Related Art Conventionally, waste of home electric appliances such as televisions, refrigerators and washing machines, or waste of OA equipment such as copy machines and personal computers has been crushed by a crusher, and then metal and plastic. It is supposed to be collected separately from non-metals.

[0003] By the way, as a crusher for crushing waste of home electric appliances and OA equipment, a required number of rotating shafts are provided via bearings in a casing in which an inlet and an outlet are formed at upper and lower portions, respectively. It is known that a crushing blade with a disk-shaped hook is alternately provided around each of the rotating shafts so that the crushing blades are freely rotatable with each other (see Japanese Utility Model Publication No. 57-13174). Gazette, Japanese Utility Model Application Laid-Open No. 62-136232, etc.).

[0004] The crusher constructed as described above is
While rotating the respective rotating shafts inward, the waste is introduced into the casing through the upper inlet, and is sequentially drawn into the gap between the crushing blades by hooks to be crushed by shearing. The crushed waste is to be separated into metals and non-metals such as plastics by a required separator such as a magnetic separator, and collected.

[0005]

However, since the above-mentioned crusher is designed to alternately crush the crushing blades with disk-shaped hooks to shear and crush them, it is inevitable that waste such as home electric appliances should be reduced to 50 to 150 mm. It can only be crushed into relatively large chips. For this reason, it is very difficult to separate and collect metals and non-metals such as plastics from pieces of crushed waste, and even more recently, household electrical appliances and OA equipment have been using metals and non-metals such as plastics. Are more difficult because there are many cases formed integrally. In addition, in order to grind the crushing blade to which it has been worn or to which foreign matter has adhered, the crushing blade must be removed and polished one by one, and the polishing work is very troublesome and troublesome.

The present invention solves the problems of the conventional example,
Pulverize waste such as home appliances suitably into fine powder,
Provide a crusher for waste products such as home appliances that not only can easily separate and collect metals and non-metals such as plastics, but also can easily grind the crushing blade as necessary. It is assumed that.
