Hereunder we will share a case of our PVC home profile (window frames, sheets, baseboards) customer that runs a pelletizing line rated at 1000 kg/h. Its powder handling systems, nearly a decade old, suffered from aging equipment, poor design, heavy dust pollution and low throughput, no longer to meet current production demands. Mconvey customized a powder handling systems upgrade to address the customer’s actual situation.
Bulk bag discharge station – a more efficient debaggin and feeding method. An electric hoist assists lifting, allowing one operator to handle the entire process, reducing labor intensity and cost.
Powder formula weigher – improves formula accuracy with multi-component precision dosing. Combines gain-in-weight and loss-in-weight methods to achieve both high output and high precision, ensuring consistent product quality.
- Larger mixing volume and optimized blade geometry for higher batch efficiency.
- High-torque synchronous drive, specially designed blades, and heavy-duty bearing sets for strong overload capacity.
- Custom S6 high-torque ultra-efficient permanent magnet motor, delivering 10–20% overall energy savings.
- Improved heating and cooling configuration to ensure uniform mixing temperature and batch-to-batch consistency.
- Blades with a special wear-resistant treatment tailored to PVC characteristics, extending service life by 3 times.

| Equipment | 500 hot mixing- 1500 cold mixing | 1000 hot mixing- 3000 cold mixing |
| 3500kg/h |
The upgraded mixer not only solved the pelletizing line’s bottleneck—it achieved an actual throughput of 3,500 kg/h, far exceeding the 1,000 kg/h design target, with enough surplus to feed two pelletizing lines simultaneously, leaving ample room for future capacity expansion.
This retrofit improved the client’s aging line with output doubled, with automated feeding, accurate dosing, and closed conveying—reducing labor, material waste, and downtime. Improved mixing uniformity and dosing accuracy enhanced dosing consistency and product quality. Shop-floor dust dropped significantly, creating a cleaner and safer work environment.
