Project Background
GreenCycle Polymer Solutions Ltd. is a plastic recycling company located in Malaysia, mainly processing industrial plastic waste such as PP and PE and converting it into recycled plastic pellets.
However, during production, particle sizes were inconsistent and contained a certain amount of plastic flakes, which directly affected the qualification rate of finished products. Therefore, the customer wanted to add a screening process to remove plastic flakes and oversized materials while ensuring that most qualified products could pass through the screen smoothly.
Customer Requirements:
- Screen opening size: 15mm
- Processing capacity: 150–200kg/h
- Product qualification rate: Above 95%
- Continuous and stable operation
- Easy cleaning and maintenance
Sanyuantang’s Solution
Through preliminary technical communication, and in order to ensure that customer requirements were fully met, the customer sent their actual materials to Sanyuantang for testing.
After analyzing the customer’s materials, Sanyuantang engineers recommended the SY-1000 Rotary Vibrating Screen.
| Parameter | Specification |
|---|---|
| Equipment Model | SY-1000 Rotary Vibrating Screen |
| Screen Type | 15 × 15 mm Square Perforated Plate |
| Screen Diameter | 1000 mm |
| Processing Capacity | 150–200 kg/h |
| Screening Efficiency | ≥95% |
| Material | SUS304 Stainless Steel |
Why Choose Rotary Vibrating Screen?
Why did Sanyuantang recommend the Rotary Vibrating Screen?
1.
The rotary vibrating screen uses a vertical vibration motor to generate three-dimensional vibration movements, including horizontal, vertical, and inclined directions. This allows plastic flakes to form a uniform spiral movement pattern on the screen surface.
Compared with ordinary linear screens, materials can be quickly dispersed and evenly distributed across the entire screening area, reducing accumulation and allowing more plastic flakes to fully contact the screen surface, improving screening efficiency and effective screening area.
2.
Plastic flakes have lightweight characteristics and good flowability. When combined with a 15×15mm square perforated screen plate, plastic pellets can quickly pass through the screen openings, avoiding blockage, material sticking, and bridging problems.
Even during long-term continuous operation, stable screening performance can be maintained, reducing manual cleaning frequency and improving equipment utilization.
3.
The SY-1000 Rotary Vibrating Screen adopts a high-quality vertical vibration motor and dynamic balancing design. During operation, it provides stable vibration performance and low noise operation, enabling continuous and uniform screening.
For plastic recycling production lines, stable vibration movement ensures consistent particle size distribution, effectively separating oversized materials above 15mm and achieving more than 95% product passing rate.
4.
The equipment adopts a modular screen structure, making screen replacement simple. When customers need to change different screen openings or clean the equipment, operations can be completed quickly, greatly reducing downtime.
Meanwhile, perforated screen plates provide better wear resistance than traditional woven mesh screens, making them more suitable for long-term screening of lightweight plastic materials.
5.
Sanyuantang rotary vibrating screens support 24-hour continuous operation. For plastic recycling companies requiring continuous production, the equipment can achieve stable all-day operation.
6.
The rotary vibrating screen features a simple structure with fewer wearing parts.Daily maintenance mainly focuses on regular inspection of the screen, sealing components, and vibration motor, resulting in lower maintenance workload.
