ZL-PC300 Plastic Granulator Machine 5.5kW 220-300kg/h
Plastic granulation differs from crushing in the final product specification: granulators produce uniform flake for direct extrusion or injection molding feed. The ZL-PC300 Plastic Granulator delivers 220-300 kg/h throughput with rotor geometry calibrated for uniform 6-8 mm flake output suitable for downstream pelletizing or direct re-injection.

The ZL-PC300 Plastic Granulator differs from basic plastic crushers in 4 ways: 1) higher blade count (12 rotating vs 9 for PC250) producing more cuts per revolution, 2) tighter rotor-screen clearance (0.2 mm vs 0.5 mm) for cleaner cuts, 3) smaller standard screen (6 mm vs 8 mm for crushers), 4) optional forced-air cooling for heat-sensitive materials. These differences produce uniform flake rather than variable-size chunks.
For buyers evaluating granulator vs crusher, the decision depends on downstream application. Granulators are required for: direct re-injection (uniform flake feeds consistently), extrusion pelletizing (uniform feed improves pellet quality), food-grade rPET (uniform flake washes and separates more efficiently). Crushers are sufficient for: landfill baling (size reduction only), basic recycling (downstream processing handles variability), waste-to-energy (no quality requirement).
The ZL-PC300 Plastic Granulator processes plastic scrap through 3 stages: 1) initial cut (rotor blades engage material at the feed opening), 2) progressive cutting (multiple blade passes reduce particle size), 3) sizing (screen controls maximum particle size, undersized material exits). The 12-blade rotor makes 4-5 cuts per second on material in the cutting chamber.
The granulation process produces flake at sizes determined by the screen: 6 mm screen produces 4-6 mm flake (suitable for direct extrusion), 8 mm screen produces 6-8 mm flake (suitable for re-injection), 10 mm screen produces 8-10 mm flake (suitable for baling). The ZL-PC300's standard 6 mm screen optimizes for direct extrusion applications.
For buyers using ZL-PC300 granulator output for direct re-injection, 4 flake quality specifications matter: 1) particle size distribution (90% within 4-6 mm range), 2) fines content (less than 5% particles below 2 mm), 3) contamination level (less than 100 ppm non-plastic), 4) thermal degradation (less than 5% molecular weight reduction during cutting). The ZL-PC300's tight rotor-screen clearance and SKD-11 blade sharpness meet all 4 specifications.
For high-quality re-injection applications, the ZL-PC300's forced-air cooling option (USD 380) reduces heat buildup during granulation, preserving molecular weight and mechanical properties of the recycled flake. Most food-grade and medical-grade applications require forced-air cooling.
For pelletizing operations, the ZL-PC300 Plastic Granulator is the first stage in a 3-stage process: 1) granulation (ZL-PC300 produces 6 mm flake), 2) extrusion (flake melts and forms continuous strand), 3) pelletizing (strand cut into 3-4 mm pellets). The ZL-PC300's 220-300 kg/h throughput matches standard 200-300 kg/h extrusion line capacity.
For pelletizing operations, granulator output quality directly affects pellet quality. The ZL-PC300's uniform flake (90% within 4-6 mm range) feeds consistently into the extruder, producing uniform pellets with 95-98% size consistency. Off-spec flake size produces off-spec pellets that command 20-40% lower market prices.
PET and HDPE are heat-sensitive materials that degrade with prolonged exposure to cutting heat. The ZL-PC300's standard rotor generates approximately 8-10 kW of cutting heat (5.5 kW input power + material friction). For sustained operation on PET or HDPE, the standard cooling may be insufficient.
The optional forced-air cooling system (USD 380) maintains rotor temperature below 60 degC during continuous operation on heat-sensitive materials. Without forced-air cooling, PET granulation is limited to 2-3 hour continuous runs before thermal cutoff. With forced-air cooling, the ZL-PC300 runs 8+ hour shifts on PET at full 300 kg/h throughput.
The ZL-PC300's granulator output quality depends on blade sharpness. Dull blades produce variable flake size, increased fines, and higher motor load (friction increases). The SKD-11 blade edge retention is 400-600 hours for granulator service (vs 600-800 hours for crusher service) due to the higher number of cuts per unit processed.
For granulator operations, blade sharpening schedule: every 400-600 hours of operation, or approximately every 4-6 weeks at 8-hour daily shifts. Blade sharpening service cost: USD 80-120 per set (9 rotating + 3 fixed). Most operations rotate 2 blade sets to maintain continuous production during sharpening service.
Q: What is the difference between ZL-PC300 granulator and ZL-PC250 crusher?
The ZL-PC300 is 5.5 kW with 12 blades and 6 mm standard screen, producing uniform flake. The ZL-PC250 is 4 kW with 9 blades and 8 mm standard screen, producing variable chunks. The ZL-PC300 is calibrated for direct re-injection; the ZL-PC250 is calibrated for baling and basic recycling.
Q: Can the ZL-PC300 granulator produce 3-4 mm flake?
Yes, with 4 mm screen (replacing the standard 6 mm). Throughput drops to 150-180 kg/h with smaller screens. The 4 mm screen produces flake suitable for film extrusion and thin-wall injection molding.
Q: What is the maximum contamination level for granulator operation?
Mild contamination (paper labels, residual adhesive) is tolerated up to 2% by weight. Higher contamination requires pre-washing or upstream sorting. Metal contamination above 1% requires magnetic separator upstream.
Q: Can the ZL-PC300 process glass-fiber-reinforced plastic?
Limited. Glass-fiber content above 15% accelerates blade wear significantly on granulator service (which requires sharper blades than crusher service). For glass-fiber materials, the PC400 with optional carbide blades is recommended.
Q: What is the ROI for granulator upgrade from crusher?
For re-injection applications, the ZL-PC300 granulator's uniform flake improves molding quality by 15-25% (less molding defects, fewer rejected parts). The defect reduction typically saves USD 5,000-10,000 annually in rejected part costs for mid-size operations. Granulator upgrade ROI: 12-18 months.
