Project Basic Information
As a core regional iron and steel production enterprise, Tianjin Iron and Steel Plant faced key cold ore screening bottlenecks in its ore pretreatment section. Before adopting equipment from Henan Quanshun Vibration Equipment Co., Ltd., the factory’s ordinary screening equipment had significant shortcomings: the processing capacity of a single unit was only tens of tons per hour, which not only failed to match the ore supply rhythm of the entire production line, leading to downtime of subsequent smelting processes due to material shortage, but also had problems such as insufficient screening accuracy and poor operational stability.
The cold ore raw material had an uneven particle size distribution (maximum feed particle size up to 150mm). If screening was incomplete, large ore blocks were likely to clog subsequent crushing equipment, and fine powder impurities would affect smelting efficiency and steel quality. Meanwhile, traditional equipment vibrated violently during operation, transmitting large dynamic loads to the foundation, which not only resulted in high equipment failure rates but also required frequent shutdowns for maintenance, seriously restricting the factory’s continuous production capacity and comprehensive benefits.
The customer urgently needed a screening system with large processing capacity, reliable operation, precise screening, and low energy consumption to break through production bottlenecks, ensure production continuity, and improve ore resource utilization.
After in-depth research on the customer’s production process and pain points, Henan Quanshun Vibration Equipment Co., Ltd. accurately configured 2 sets of LZSF3090 double-shaft linear vibrating screens for Tianjin Iron and Steel Plant based on the core technical advantages of the LZS series large cold ore vibrating screens, forming an efficient and coordinated cold ore screening solution that perfectly matches the high-intensity, continuous production needs of iron and steel plants.

After the two sets of LZSF3090 large cold ore vibrating screens were put into operation, they quickly became the core equipment in the ore pretreatment section of Tianjin Iron and Steel Plant, creating significant value for the customer:
In response to the rigid demand for cold ore screening in our iron and steel plant, the two sets of LZSF3090 large cold ore vibrating screens provided by Henan Quanshun Vibration Equipment Co., Ltd. have successfully built an efficient and stable screening system, completely solving the long-standing problems of insufficient production capacity and poor screening accuracy that plagued us. The equipment has large processing capacity, reliable operation and convenient maintenance, fully adapting to the high-intensity continuous production scenario of iron and steel plants.
Henan Quanshun has a professional technical team and a complete service system, providing precise support from scheme design to equipment commissioning, demonstrating expert-level industry literacy. This set of screening solutions not only improves our production efficiency and product quality but also gives us a distinct advantage in the competition of the same industry, making it a long-term trusted partner.
