Case Study: Boosting Throughput by 30% in a PET Recycling Plant

Case Study: How We Helped a PET Recycling Plant Increase Output by 30%

In the competitive world of plastic recycling, throughput is profit. Recently, we partnered with a recycling facility that was facing a classic bottleneck: their primary grinder was struggling to keep up with their washing line, causing frequent, costly downtime.

In this edition of our Case Studies & Results series, we explore how a targeted machinery upgrade transformed their production efficiency.

The Challenge: The Bottleneck Effect

Our client, a PET bottle processor, was seeing inconsistent flake quality and throughput drops whenever they switched between different bottle densities. Their existing system was causing:

Bottlenecks: The grinding stage could not process material fast enough to feed the dryer.
Energy Waste: The motor was over-drawing power due to inefficient blade geometry.
High Contamination: The lack of a specialized separation step meant downstream quality suffered.

The Solution: Targeted Machinery Integration

Instead of replacing the entire line (a massive capital expenditure), we performed a “system-sync” upgrade:

Blade Geometry Re-design: We replaced the existing blades with our high-torque, precision-ground Industrial Shredder Blades, optimized specifically for PET density.
Cyclone Blower Integration: We integrated a high-efficiency Cyclone Blower to ensure the material was moved seamlessly from the grinder to the washing stage without air-drag or clogs.
Process Automation: By fine-tuning the feed rate through an automated SS 304 Hopper Machine, we stabilized the flow, allowing the downstream equipment to run at peak capacity.

The Results: Data-Driven Performance

After two weeks of operational testing, the results were clear:

30% Increase in Throughput (kg/hr): By eliminating the bottleneck, the plant achieved a consistent flow that exceeded their previous benchmarks.
15% Reduction in Energy Costs: The optimized blade geometry required less amperage, leading to significant monthly power savings.
Improved Flake Purity: The integrated material handling system reduced dust cross-contamination by 20%.

Conclusion: Small Changes, Big Impact

This project is a perfect example of why Balveer Engineering prioritizes Recycling Solutions & Tech that can be integrated into existing lines. You don’t always need a massive investment to scale your plant—often, it’s about optimizing the weak links in your process.
