ZL-PC250 Manufacturing Plastic Crusher 4kW for Factory Production | ZILLION
Manufacturing workshops producing 30-80 kg/h of production scrap need a crusher that integrates into the manufacturing workflow without disrupting production schedules. The ZL-PC250 Manufacturing Plastic Crusher delivers 250 kg/h throughput with the 9-blade SKD-11 rotor and 4 kW motor sized for the typical 3-5 machine injection molding cell. For manufacturing workshop operators, the ZL-PC250 is the workhorse machine.

Manufacturing workshops running injection molding generate three scrap streams with distinct throughput requirements: sprues (10-20% of finished part weight, sharp cylindrical shapes), runners (5-15% of finished part weight, branching channels), and off-spec parts (2-5% of finished parts, irregular shapes). For a manufacturing workshop producing 100 tonnes of finished parts monthly, total scrap generation is 17-40 tonnes/month or 80-200 kg/day at single-shift operation.
The ZL-PC250 at 250 kg/h throughput processes the daily scrap generation in 5-10 hours, leaving 15+ hours of throughput reserve for expansion, post-consumer streams, or second-shift operation. Most manufacturing workshops operate the ZL-PC250 in single-shift mode for 4-6 hours daily, accumulating 25-40 hours of weekly operating time.
Manufacturing workshops pursuing closed-loop scrap recycling recover 90% of production scrap as reusable flake for re-injection. The ZL-PC250 produces 8 mm screen flake suitable for direct re-injection after color verification. Each closed-loop cycle reduces polymer molecular weight by 2-5% (measured as Melt Flow Index increase).
For manufacturing workshops running 100% closed-loop production scrap, the typical cycle count is 4-6 before molecular weight degradation requires blending with 30-50% virgin resin. The ZL-PC250 with sharp SKD-11 blades cuts cleanly without thermal degradation, preserving molecular weight and impact strength across the 4-6 cycle range.
The ZL-PC250 supports a manufacturing workshop running 3-5 injection molding machines (50-300 ton clamping force each). For workshops running 3 small machines (50-100 ton), the ZL-PC250 processes the combined 30-50 kg/h scrap output. For workshops running 5 medium machines (100-300 ton), the ZL-PC250 handles 60-100 kg/h combined scrap output.
For manufacturing workshops expanding to 6+ machines, the ZL-PC300 (5.5 kW, 220-300 kg/h) is recommended. For 10+ machines, the PC400 (7.5 kW, 400-500 kg/h) becomes the appropriate capacity match. The ZL-PC250's role is the mid-size workshop sweet spot of 3-5 machine cells.
The ZL-PC250 Manufacturing Plastic Crusher includes 4 safety features beyond basic regulatory compliance: 1) safety interlock on the feed cover (stops rotor when opened), 2) emergency stop button (red mushroom button, accessible from feed side), 3) rotor brake (stops rotor within 3 seconds of power cutoff), 4) overload protection (motor thermal sensor trips at 110% rated current).
For manufacturing workshops operating under ISO 45001 occupational safety standards, the ZL-PC250's 4-point protection system satisfies the highest safety requirements. Most workshops add the optional acoustic enclosure (USD 280) to reduce noise below 75 dB for operator comfort during 8-hour shifts.
For manufacturing workshops calculating daily operating cost: electricity 4 kW x 6 hours/day x USD 0.10/kWh = USD 2.40; blade allocation 0.5 set x USD 120 = USD 60/year / 250 days = USD 0.24; bearing service allocation USD 60/year / 250 days = USD 0.24; labor 0.5 hr x USD 8 = USD 4.00; overhead allocation USD 9.00. Total daily operating cost: USD 16.
At 250 kg/h x 6 hours/day = 1,500 kg/day processed, the daily operating cost is USD 0.011 per kg. Compared to recovered resin value of USD 200-500 per tonne, the operating cost represents 2-5% of material value. This low operating cost ratio makes the ZL-PC250 a cost-effective addition to any manufacturing workshop.
Q: How is the ZL-PC250 different from PC180 for manufacturing use?
The PC250 is 4 kW (vs 2.2 kW for PC180), 250 kg/h throughput (vs 120-150 kg/h), 9-blade rotor (vs 6-blade), 250 kg weight (vs 130 kg). The PC250 supports 3-5 injection molding machines; the PC180 supports 1-2 machines.
Q: Can the ZL-PC250 process glass-fiber-reinforced ABS?
Limited. Glass-fiber content above 20% accelerates blade wear on the standard SKD-11 blades. For glass-fiber ABS, the optional carbide-tipped blade upgrade (USD 280) extends blade life by 3-4x. Above 35% glass-fiber content, the PC300 or larger is recommended.
Q: What screen size is best for direct re-injection?
8 mm screen for direct re-injection of sprue and runner scrap. Smaller screens (5-6 mm) produce excessive fines that cause molding defects; larger screens (10-12 mm) require downstream granulation.
Q: How does the ZL-PC250 handle contamination (paper labels, residual adhesive)?
Mild contamination (paper labels, residual adhesive) passes through without damage. For high-contamination streams (food packaging, agricultural film), pre-washing is required. The ZL-PC250's reversing switch clears contamination jams in 2-3 minutes.
Q: Can the machine be operated by a single worker alongside molding machine tending?
Yes. The ZL-PC250's low operator requirement (0.5 hours per 8-hour shift) allows a single worker to tend both the injection molding machine and the crusher. Most manufacturing workshops assign crushing tending to the molding machine operator during natural production breaks.
