Product Overview
The SM40 Spiral Silo Forming Production Line is a specialized forming line designed for manufacturing medium-sized spiral steel silos, catering to users with high demands for silo forming quality and production efficiency. The line's equipment ensures structural strength while balancing flexibility and stability, making it widely applicable for producing steel silos for grain and various bulk materials.
Performance Features
1. The SM40 processes materials with thicknesses ranging from 2–4mm, delivering stable and reliable forming and bending capabilities to meet the manufacturing needs of medium-thickness steel silos.
2. When using 495mm-wide strip material, the effective forming width is approximately 350–370mm. It offers high forming precision and robust interlocking structures, making it suitable for continuous production.
3. The equipment can manufacture spiral steel silos with diameters ranging from 4–20m, covering common silo requirements. Forming and bending speeds are approximately 4–6m/min, achieving a good balance between efficiency and forming quality.
Core Equipment
Decoiler
As the central hub for raw material supply in medium-to-large-scale storage production, the SM40 uncoiler prioritizes optimized load capacity and feeding precision, accommodating heavy coils with thicknesses ranging from 2-4mm. It completely resolves issues such as stuttering, misalignment, and sheet deformation that occur during heavy-load operation in traditional uncoilers. Featuring a reinforced chassis constructed from high-strength alloy steel welds, its load capacity exceeds the SM30 by over 30%, ensuring stable continuous uncoiling of heavy coils.
Spiral Forming Machine
The SM40 forming machine optimizes structural design and adjustment range for arcs in silos ranging from 4 to 20 meters in diameter. It addresses industry pain points such as uneven arcs in medium-to-large silos and the need for secondary corrections after forming. Featuring multiple sets of progressive forming rollers integrated with an upgraded cam drive system, it ensures smooth forming of 2-4mm thick heavy plates while preventing issues like plate cracking and stress concentration caused by single-pass forming.
Bending Machine
The SM40 Bending Machine focuses on upgraded seaming dies and drive systems. Leveraging optimized German-imported seaming technology, it achieves tight seaming of heavy plates. This ensures silo body sealing integrity and load-bearing capacity, meeting the long-term bulk material storage demands of medium-to-large silos. Bending speeds reach 4-6 meters per minute, enabling continuous spiral forming for silos ranging from 4 to 20 meters in diameter without segmented welding. This eliminates the drawbacks of traditional segmented welding processes, such as weld leakage and insufficient strength.
