Two, engineering plastics particle is added to from feed pipe (111) in device body (110), engineering plastics particle drops into sieve On plate (130), large-scale particle is dropped into after screening in the first treatment trough (1131), and large-scale particle drops into second processing slot (1132) in;
Three, start the second motor (162), grinding device is made to crush the large-scale particle in second processing slot (1132), the first processing Small particle in slot (1132) can crush cutting blade (311) by first in drive shaft (160) and crush;
Four, crushed material is taken out from the first discharge hole (114) and the second discharge hole (115), that is, crushes and completes.
