ZL-PC400 Plastic Lump Crusher 7.5kW for Blow-Molding & Rotomolding | ZILLION
Blow-molding and rotomolding operations generate large plastic lumps that standard crushers cannot process efficiently. The ZL-PC400 Plastic Lump Crusher delivers 400-500 kg/h throughput with rotor geometry calibrated for large lump processing, including the unique requirements of thick sections and large irregular shapes.

Mid-range shredders typically handle lumps up to 200 mm diameter before jamming on large irregular shapes. The ZL-PC400 Plastic Lump Crusher has a 380 x 320 mm feed opening and 410 x 340 mm crushing chamber, which accepts lumps up to 350 mm diameter without pre-cutting.
For blow-molding and rotomolding operations generating lumps from 100-350 mm diameter, the ZL-PC400's rotor geometry handles the variable lump sizes without operator intervention. The 15-blade rotor makes progressive cuts through large lumps, reducing them to uniform flake over multiple revolutions.
Blow-molding operations generate large hollow forms (containers, tanks, automotive ducts) that require specialized processing. The ZL-PC400's rotor geometry cuts through HDPE blow-molded containers at 350-400 kg/h, with throughput varying based on wall thickness and container size.
For blow-molding operations with 50-150 kg/h scrap generation, the ZL-PC400's 400-500 kg/h capacity provides 3-8x throughput reserve. The modular blade geometry handles containers from 5L (small automotive) to 1000L (large industrial tanks) without screen change.
Rotomolding operations generate thick-section lumps (5-15 mm wall thickness) that require higher cutting torque than standard injection molding scrap. The ZL-PC400's 7.5 kW motor provides 50% more torque than the PC300 (5.5 kW), enabling rotomolding lump processing at 250-300 kg/h sustained throughput.
For rotomolding operations producing large industrial containers (water tanks, material handling bins, playground equipment), the ZL-PC400's heavy-duty rotor handles the thick sections without stalling. Most rotomolding operations report 95%+ uptime availability with the ZL-PC400.
HDPE drums (200L, 4-8 mm wall) are a major blow-molding product. The ZL-PC400 processes whole drums at 300-400 kg/h throughput (lower than rigid plastic flake due to wall thickness and cylindrical shape). For drum recyclers receiving mixed sizes, the ZL-PC400 handles 5L to 200L containers without screen change.
For blow-molding operations producing drums in-house, the ZL-PC400 enables closed-loop drum recycling. The 8 mm screen output feeds directly into the drum blow molding line after color sorting, achieving 90% material recovery at USD 500/tonne savings vs virgin HDPE.
Thick-walled containers (10-15 mm wall, typically industrial chemical containers, marine floats, large material handling bins) require specialized processing due to cutting torque requirements. The ZL-PC400's 7.5 kW motor handles 10 mm wall at 250-300 kg/h, 15 mm wall at 180-220 kg/h.
For thick-wall container recyclers, the ZL-PC400's torque reserve is essential. Mid-range 4-5.5 kW machines stall on 15 mm wall material, requiring pre-cutting. The ZL-PC400's 7.5 kW motor provides the torque headroom for sustained thick-wall processing without operator intervention.
Closed-loop blow-molding recycling recovers HDPE from production rejects and reprocesses into new containers at the same facility. The ZL-PC400 Plastic Lump Crusher produces chips at 10-12 mm screen size that feed directly into the blow molding line after hot-air drying and color sorting.
For a mid-size blow-molding operation processing 3,000 tonnes/year of production scrap, the ZL-PC400's 350 kg/h throughput processes the daily input in 3-4 hours. The annual HDPE recovered is 2,700 tonnes (90% recovery rate), commanding USD 700/tonne vs virgin USD 1,100/tonne. Annual savings: USD 1.08 million. Payback period: 1.4 months.
Blow-molding operations generate lumps in irregular shapes and sizes that require handling. The ZL-PC400's 380 x 320 mm feed opening accepts most lumps without pre-cutting, but oversized lumps (>350 mm) require pre-cutting via band saw or hydraulic shear (USD 3,000-8,000 separate equipment).
For blow-molding operations with high lump volume, a feed conveyor (4-meter, USD 480) carries lumps from collection bins to the ZL-PC400 feed opening, eliminating manual lifting. The ZL-PC400's 450 kg weight requires reinforced flooring for installation.
Q: What is the maximum lump size the ZL-PC400 can process?
350 mm diameter for direct feed without pre-cutting. Larger lumps require band saw or hydraulic shear pre-cutting. The 380 x 320 mm feed opening and 410 x 340 mm crushing chamber accommodate most blow-molding and rotomolding lump sizes.
Q: Can the ZL-PC400 process rotomolding scrap?
Yes, at 250-300 kg/h. Rotomolding scrap has thick sections (5-15 mm wall) requiring higher cutting torque than injection molding scrap. The ZL-PC400's 7.5 kW motor provides the torque reserve for thick-wall processing.
Q: What screen size for downstream blow molding?
10-12 mm screen for direct feed to blow molding extrusion lines. Smaller screens (6-8 mm) require additional granulation and add cost without quality benefit for blow-molding applications.
Q: Can the ZL-PC400 process glass-fiber rotomolding products?
Limited. Glass-fiber content above 15% accelerates blade wear. The optional carbide-tipped blade upgrade (USD 380) extends blade life by 3-4x for high-volume GF processing.
Q: What is the typical payback period for blow-molding operations?
For a 3,000 tonnes/year blow-molding operation: 1-3 months. The ZL-PC400 capital cost is recovered in the first month of closed-loop operation due to high resin savings (USD 400/tonne on virgin HDPE replacement).
