Client Background
ChemTec GmbH, a leading chemical manufacturer based in Ludwigshafen, Germany, specializes in producing high-purity catalysts for the petrochemical industry. The company faced critical challenges in screening catalyst particles (20-200μm) – their existing equipment struggled with low precision, excessive material damage, and inefficient operation in tight workshop spaces, leading to 15% material waste and frequent production bottlenecks.
Challenges
- Need for high-precision classification of catalyst particles to meet strict purity standards (error margin ≤3%).
- Minimize catalyst damage (angular particles would reduce catalytic activity) during screening.
- Adapt to limited installation space (workshop area ≤10㎡) while maintaining high throughput.
- Resist corrosion from chemical dust and ensure stable operation in a controlled, low-noise environment.
Solution
After evaluating ChemTec’s requirements, Yingda Heavy Industry customized a ZWYB-2000 Swinging Vibrating Screen with the following tailored features:
- 3 layers of circular screens (pore sizes: 20μm, 80μm, 200μm) to achieve precise three-level classification and protect catalyst integrity.
- Enhanced corrosion-resistant stainless steel screen box and dust-proof seals to adapt to chemical working conditions.
- Compact structural design (2.80㎡ screen area, small footprint) to fit the limited workshop space.
- High-efficiency exciter with vibration isolators to reduce operating noise to ≤75dB(A) and ensure stable amplitude.
Implementation & Results
The ZWYB-2000 was installed in March 2025, with Yingda’s after-sales team providing on-site guidance to complete calibration and commissioning within 1 day. Key outcomes after 3 months of operation:
- Screening precision reached 96%, exceeding the client’s requirement of ≤3% error margin.
- Catalyst damage rate dropped from 12% to 2.5%, maintaining optimal catalytic activity.
- Production throughput increased by 22%, eliminating previous bottlenecks.
- Material waste reduced by 15%, saving approximately €48,000 in raw material costs annually.
Client Testimonial
“The ZWYB-2000 has perfectly solved our screening challenges,” said Markus Weber, Production Manager at ChemTec GmbH. “Its compact design fits our workshop perfectly, and the high precision and low material damage have significantly improved our product quality and operational efficiency. Yingda’s professional customization and timely after-sales support make them a reliable partner.”
