Q1: Why is my plastic recycling line’s electricity bill increasing month by month?

A: Traditional single-screw extruders waste 60-70% of energy overcoming back-pressure and internal slippage, consuming 350-400 kWh/ton when processing bulky materials. Our counter-rotating parallel twin-screw system utilizes positive displacement conveying with zero back-pressure. Combined with permanent magnet servo motors and electromagnetic induction heating, energy consumption for LDPE agricultural film recycling drops below 220 kWh/ton—delivering 35-40% electricity cost savings.

Q2: My agglomerator requires frequent maintenance and repair costs are too high. What can I do?

A: Agglomerators rely on high-speed friction (1,000-1,500 RPM) to generate heat and densify material, resulting in rapid blade wear and excessive motor loading. Our solution eliminates the agglomerator entirely, replacing it with shredding plus variable-diameter spiral forced feeding. This removes friction heat losses and high-speed component maintenance, reducing equipment failure rates by over 60% and saving tens of thousands in annual maintenance costs.

Q3: My single-screw extruder cannot achieve target output. How can I meet customer orders?

A: Single-screw extruders depend on frictional conveying, causing bulky materials to slip easily; increasing RPM leads to overheating. Our counter-rotating twin-screw system mechanically locks material in the intermeshing zone for positive displacement feeding. Operating at just 40-50 RPM achieves the output equivalent to a single-screw running at 120 RPM, with stable feeding and no bridging—delivering 280-300 kg/h or higher for PP fiber materials.

Q4: My recycled pellet quality is inconsistent, causing frequent customer complaints. How can I fix this?

A: Quality variation typically stems from inconsistent thermal history and insufficient filtration. Our three-stage tandem extrusion process completes plasticization in a single heating cycle, minimizing thermal degradation. Two-stage filtration (60-80 mesh coarse + 120-200 mesh fine) removes contaminants, while ±1°C temperature control precision ensures melt index variation stays within ±10%. The result is consistently superior pellet appearance and mechanical properties.

Q5: Bulky materials won’t feed properly, causing frequent bridging and line stoppages. What’s the solution?

A: Bulky materials (bulk density 0.03-0.08 g/cm³) have large volume and tend to bridge in the feed throat. We solve this with an oversized feed opening (350×350 mm), ultra-deep screw channels (22-25 mm), and variable-diameter spiral pre-compaction that increases material density to 0.25-0.30 g/cm³ before entering the main extruder. Combined with optional side feeding, this completely eliminates bridging and feed interruptions.
