Recently, GN Separation successfully installed, commissioned, and officially launched a complete set of vibrating screens in a key gasification slag treatment project for an energy group in Inner Mongolia. This achievement underscores the recognition of GN Separation's technological prowess and high-end equipment in solid-liquid separation and fine classification by large-scale energy enterprises, providing vital technical support for their solid waste resource utilization and environmentally sustainable production practices.
Project Challenges and GN's Tailored Solutions
Gasification slag, a byproduct of the coal chemical process, requires a multi-step treatment approach involving slag separation, classification, and dewatering. These steps impose stringent demands on the reliability, efficiency, and dewatering performance of screening equipment. To meet the unique needs of this project, GN Separation's technical team devised a customized intelligent screening solution.
Core Slag Separation: Box-type Exciter Linear Screening
GN Separation's large linear vibrating screen utilizes a robust box-type exciter as its vibration source, ensuring powerful, stable operation and extended service life. Its superior linear motion trajectory enables it to efficiently handle large volumes of material with varying slag quality, achieving initial efficient separation and medium removal of gasification slag. This sets a solid foundation for subsequent processing stages.
Fine Classification: Synergistic Frequency Vibrating Screen
The synergistic frequency vibrating screen, a flagship product of GN Separation, is celebrated for its innovative synergistic frequency coordination technology. This technology allows precise control over the vibration frequency and amplitude of the screening surface, facilitating fine classification of materials with different particle sizes. With high separation accuracy and substantial processing capacity, it effectively meets the customer's requirements for classifying gasification slag into different particle size fractions, significantly enhancing the material's added value.
Efficient Dewatering: Small High-frequency Fine Screen
To address the high-frequency and low-moisture demands of the dewatering section, the small high-frequency fine screen plays a pivotal role. Equipped with a high-frequency vibration motor, it generates high vibration frequency and small amplitude, effectively breaking the surface tension of water and promoting rapid water separation. This significantly reduces the moisture content of the filter cake. Its compact design makes it ideal for spatial arrangements in process steps, demonstrating exceptional dewatering efficiency.
Project Outcomes and Future Prospects
All equipment has been successfully installed and commissioned, operating smoothly with all performance indicators meeting or surpassing design expectations. The successful implementation of this system has enabled the enterprise to achieve efficient and environmentally friendly treatment of gasification slag, promoting resource recovery and utilization while reducing operational costs. This demonstrates favorable economic and environmental benefits.
The success of this collaboration reaffirms the significant advantages of GN Separation's mining vibrating screen products in terms of technological sophistication, equipment reliability, and solution professionalism. GN Separation will continue to adhere to its philosophy of "technological innovation and quality first," consistently providing more efficient and intelligent screening solutions for industries such as coal, mining, chemicals, and environmental protection. It is committed to working hand in hand with customers to advance green and sustainable industrial production.
