PET Recycling Plant Upgrades from Dry Crusher to TL4080W Water Washing Crusher, Double Improvement in Capacity and Cleanliness

Traditional PET recycling plants adopting separate dry crushing and pre-washing processes generally face five industry pain points: high blade loss, excessive impurities in flakes, excessive workshop dust, large floor occupation and high labor costs. Finished products can only be sold as low-grade conventional materials with limited profit margins. A large-scale PET flake recycling plant in Henan eliminated the old dry crushing production line and adopted the integrated wet TL4080W water washing crusher to complete crushing and water washing in one step, realizing multi-dimensional upgrades of grade improvement, environmental compliance and cost reduction, which can be directly replicated by domestic flake and film recycling plants.

1. Project Background

A local large-scale PET flake recycling plant in Henan mainly engages in recycling, crushing and deep processing of waste mineral water bottles and beverage bottles, with a daily processing capacity of 7 tons of waste bottles and finished flakes sold to downstream granulation factories. Before renovation, the plant adopted the traditional separate process of 30kW dry crusher and independent external pre-washing tank, with long-term unsolvable production and compliance problems restricting profit expansion:

1. High blade maintenance cost: Dry high-speed friction crushing without cooling structure causes continuous high-temperature passivation of cutters, requiring shutdown, disassembly and polishing every 7 days, resulting in high monthly costs for blade consumables and labor, and frequent production interruptions;
2. Low flake grade and selling price: Dry crushing only physically breaks materials, leaving strong adhesive glue, sediment and oil stains on bottle surfaces. The external pre-washing tank has limited cleaning effect, resulting in finished flakes with many impurities and poor whiteness, only available for low-price conventional sales;
3. Large floor occupation and redundant labor: Two separate processes (crushing and pre-washing) with two sets of conveying equipment occupy 25㎡ of workshop area, requiring special personnel for material transfer between processes with fixed shift workers and serious labor waste;
4. Excessive workshop dust against environmental standards: Dry crushing causes widespread dust diffusion, leading to full-load operation of dust removal equipment, high energy consumption and multiple environmental rectification warnings with shutdown risks;
5. Low water circulation rate: Open drainage of external pre-washing tanks prevents sewage recycling, resulting in huge daily water consumption and high water cost.

In 2026, the plant completed full process upgrade, completely removing old dry crushers, independent pre-washing tanks and supporting conveying equipment, and purchased one TL4080W water washing crusher (30kW integrated wet crushing and washing machine) to rebuild the wet recycling production line.

2. Customized Wet Production Line Renovation Solution
3. Core crushing host: Adopt TL4080W water washing crusherwith 30kW main crushing power + original 5.5kW waterproof spiral conveyor and 460×800mm extended crushing cavity. Bundled and scattered waste bottles can be directly fed without sorting;
4. Water circulation saving renovation: The water inlet of the host is connected to the plant sedimentation filtration tank, realizing closed-loop circulating water supply after sewage filtration, reducing sewage discharge and water cost;
5. Seamless production line connection: The spiral discharge port is directly connected to the feed end of the original friction cleaner, realizing fully automatic closed conveying of wet flakes and seamless docking with subsequent deep hot rinsing, flotation and dehydration processes without manual transfer;
6. Particle size matching downstream: Adopt the original 240mm standard screen aperture to keep consistent flake particle size with the old process, fully meeting the fixed size procurement requirements of downstream granulation and slicing customers without parameter adjustment.
7. Measured Multi-dimensional Efficiency Improvement and Cost Reduction Data
8. 55% reduction in blade maintenance cost, non-stop production: Full-cavity water circulation constant temperature cooling completely solves the high-temperature wear problem of dry crushing. SKD wear-resistant blades can operate stably for 16 days per polishing, halving polishing and replacement frequency. Monthly comprehensive costs of blade procurement, disassembly and maintenance are reduced by 55%, downtime is shortened and effective crushing capacity is increased by 22%.
9. Upgraded flake grade with a premium of 300 RMB per ton: Synchronous high-pressure water washing during crushing removes glue, labels, sediment and oil stains, greatly improving pre-cleaning effect and reducing the cleaning load of subsequent rinsing equipment by 40%. Finished high-whiteness first-grade clean flakes with high purity and transparency achieve a sales premium of 300 RMB per ton, bringing considerable monthly additional revenue based on 7-ton daily capacity.
10. Streamlined site and 60% labor cost reduction: A single TL water washing crusherreplaces two sets of equipment (dry crusher + pre-washing tank), saving 25㎡ of workshop space for raw material stacking and capacity expansion. Inter-process material transfer posts are cancelled, cutting 2 workers per shift and 6 fixed workers in three shifts, reducing monthly transfer labor costs by 60%.
11. Dust-free wet operation, year-round environmental compliance: Fully enclosed wet crushing eliminates dust diffusion from the source, meeting environmental air quality standards, reducing dust removal equipment load and power consumption by 38%. The plant has passed multiple environmental dust inspections without rectification notices or shutdown risks with standardized workshop environment.
12. Minimal maintenance and ultra-low failure rate: The integrated thickened waterproof and anti-corrosion steel fuselage adapts to all-weather water and sewage operation. The spiral lifting transmission structure is simple and wear-resistant, with no water leakage, transmission jamming or cutter rust failures after two months of operation. Daily maintenance only includes regular screen cleaning and bearing anti-rust lubrication, accessible for zero-basic operators with low maintenance threshold.
13. Closed-loop water circulation, 42% lower water cost: The supporting sedimentation tank closed-loop water circulation system realizes repeated utilization of filtered production sewage without continuous fresh water intake, cutting monthly production water consumption cost by 42% and meeting environmental discharge standards.
14. User Feedback from Factory Manager

Factory Manager Comment: PET recycling factories are troubled by high blade costs, low flake prices and dust environmental inspections. The TL4080W water washing crusher solves all core pain points in one stop. Integrated crushing and washing, water cooling protects cutters to save costs, and ultra-clean flakes bring higher profits. One machine replaces two old devices, saving site and labor. The full-series TL wet models cover 22kW small workshop to 37kW heavy-duty large models, compatible with PET bottles, agricultural films and miscellaneous plastics, suitable for recycling plants of all scales with stable long-term wet production.
