DEVICE FOR PRODUCTION OF POWDER FROM POLYMERIC MATERIAL Russian patent published in 1995 - IPC

FIELD: milling of polymeric materials. SUBSTANCE: device is provided with means for cooling the body and rotor. The height of the pins and/or plates is selected within (h₃-1,5) to (h₃-0,2) mm, where h₃ the width of the annular gap, mm. The sum of the heights of the pins and/or plates on the surface of the body and rotor is selected within (h₃-1,5) to (h₃-0,2) mm. The kneading pins and/or plates have an invariable section in height. The total area of their cross- sections makes up 0.05 to 0.3 of the area of the side surface on which they are located. The pins and/or plates are located forming periodically repeating structures. EFFECT: improved design. 4 cl, 5 dwg
