Featuring robust blades, low noise operation, and a capacity of 100–150 kg/h, the ML180 offers reliable pre-processing for small to medium-scale recycling operations.

ECS85 Compactor Plastic Film Pelletizing Machine

The ECS85 Compactor Plastic Film Pelletizing Machine is a compact, integrated system designed for recycling clean PP, PE, and LDPE films—such as shopping bags, shrink wrap, and agricultural film. It combines a cutter compactor and single-screw extruder to directly convert lightweight film into dense, uniform pellets. With low energy consumption, stable output, and minimal pre-processing requirements, the ECS85 is ideal for small to medium recyclers seeking an efficient, space-saving solution for soft plastic waste.

Melting & Extrusion Module	Single/twin-screw extruder, multi-zone heater, temperature controller	Uniformly melts film flakes; temperature tailored by material (PP: 170–220°C, PE: 160–210°C, LDPE: 150–200°C); extrudes molten plastic as strand.
Filtering & Impurity Removing Module	Coarse/fine filters, magnetic separator, backwashing device	Removes residual contaminants; magnetic separator captures metal; backwashing enables online filter cleaning without stopping production.
Shaping & Cooling Module	Shaping die, water cooling tank, air cooler, conveyor belt	Forms molten strand to fixed diameter and rapidly cools it for dimensional stability and hardness.
Pelletizing Module	High-speed cutter, gap adjustment device, particle separator	Cuts cooled strand into uniform 2–6 mm pellets; adjustable gap controls size; separates pellets from fines.
Drying & Screening Module	Hot air dryer, vibrating screen, cyclone separator	Dries pellets to ≤0.3% moisture; screens out oversized/undersized particles; removes dust for consistent product quality.
Control & Electrical Module	PLC cabinet, touchscreen, sensors (temperature, pressure, current, level)	Enables full automation, real-time monitoring, automatic fault alarm/shutdown, and production data logging for traceability.

Frequently Asked Questions

What is the delivery time and payment terms?

Yes. The integrated model is equipped with an enhanced cleaning module (bubble cleaning + high-pressure spray), which can effectively remove soil and oil stains on the film surface; the subsequent centrifugal dehydrator can dehydrate the film to moisture content ≤1%, ensuring the melting effect. For severely polluted materials, an additional chemical cleaning module can be customized.

Can PP, PE and LDPE film materials be processed at the same time?

Yes. The twin-screw model is specially designed for mixed materials; it has strong mixing and melting capacity, which can uniformly mix and melt PP, PE and LDPE film materials. It is recommended to pre-classify the materials if high-purity single-material pellets are required, and the single-screw model can be used for separate processing.

What is the daily maintenance requirement of the equipment?

Daily maintenance mainly includes: 1) Clean the crusher, cleaning tank and filter screen regularly to avoid impurity accumulation; 2) Check the wear of the crusher blade and pelletizing cutter, and replace them in time when the wear is excessive; 3) Lubricate the transmission parts (bearing, gearbox) regularly; 4) Check the heating system and sensors to ensure accurate temperature control and parameter monitoring.

What is the delivery time and payment terms?

The delivery time for standard models is 25-35 days; customized models (such as integrated models with enhanced cleaning functions) take 35-45 days. We support flexible payment terms (T/T, L/C, DP) and accept small-batch trial orders. For bulk orders, we provide preferential pricing and phased delivery services.

Do you provide sample testing services?

Yes. Customers can send their PP/PE/LDPE film waste samples to us; we will process them into finished pellets using the corresponding model equipment and send the samples back for inspection. We also provide test reports (pellet purity, moisture content, particle size) to help customers confirm the equipment performance. The courier cost is borne by the customer.
