SWP-400 type high-speed plasticcrushing machineryis the special equipment for recycling disused trivial materials in producing and grinding heat-sensitivity plastic such as pvc pp po and so on.Features: 1) Temperature goes up slightly: this machine can cool the processing of heat- sensitivity materials by water cycle system 2) Stability: this machine pulverizes stuff just once (no sifter), the working principle is that the impeller rolls at high speed and produces ultrasonic vortex which makes vibrancy of high-frequency.
