[

However, in the apparatus for crushing and separating waste synthetic resin according to the prior art 1, the electrostatic property and the centrifugal force generated inside the main body, when the waste particles adsorbed or fixed to the inner wall are removed, There is a problem that the pulverization time is increased in the process of introducing paper waste, etc. into the inside of the main body again.

2 is a central multi-view drawing showing the internal structure of a pulverizing and separating apparatus for a waste synthetic resin in Patent Publication No. 2002-0089598 (hereinafter referred to as "Prior Art 2").
