The present invention relates to a polypropylene resin modified micro-particle pelletizing line equipment, comprising a feeding system, a twin-screw extruder, a cooling water tank, a strand dryer, a pelletizer, a vibrating screen, and packaging equipment; The pelletizer is a dual-speed micro-particle pelletizer comprising a frame and a rubber roller mounted thereon. A knurled shaft is positioned below the rubber roller, with a feed chute on one side beneath the roller. Opposite the feed chute, a moving blade and a fixed blade are mounted on the roller. The frame features a discharge port positioned below the moving blade. The moving blade is mounted on the frame via a moving blade shaft, with coupling bearings installed at both ends of the shaft for blade shaft mounting. A first variable-speed motor is connected to the rubber roller, while a second variable-speed motor is connected to the moving blade shaft. A fixed blade adjustment component is positioned below the knurling shaft, and a knurling shaft adjustment component is located beneath the feed chute. Following the optimized combination of equipment in the granulation line, uniformly sized polypropylene resin microparticles with particle weight of 0.3–2 mg and production capacity of 80–300 kg/h can be produced.
