Thermoplastic particle granulator, heater and homogenizer comprises a container with a an angled base and rotated flat blade carrier or a rotated blade carrier disc with a turned up edge

摘要

One or more rotating disc-shaped blade carriers(4) with knife blades(9) are located inside and close to the base(2) of a container. The outer edge(8) of one or more blade carriers is bent upwards to form an angled rim which diverts centrifuged plastic particles upwards onto the container side wall(3) from where they circulate back into the container central area. One or more rotating disc-shaped blade carriers(4) with knife blades(9) are located inside and close to the base(2) of a container. The outer edge(8) of one or more blade carriers is bent upwards to form an angled rim which diverts centrifuged plastic particles upwards onto the container side wall(3) from where they circulate back into the container central area. Alternatively a section of the container sidewall is angled so that centrifuged particles from a completely flat blade carrier are diverted upwards. The maximum angle(delta) of the turned-up blade carrier rim or container base relative to the horizontal is 10-50degrees, preferably 25-40degrees, more preferably 30-40degrees. The turned-up section of the blade carrier extends over 0.05-0.12%, preferably 0.06-0.08% of the blade carrier radius.
