Spiral Steel Silo Forming Machine

Description of Spiral Steel Silo Forming Machine:
For years we have focused on the spiral steel silo manufacturing technology, which is the world's most advanced technology for steel silo. Different from other steel silo forming machines, this spiral steel silo forming machine produces steel silo by a special kind of seam lock, not by welding or assembling. Our SM40 forming machine is similar to Germany Lipp machine.

Working Principles of Spiral Steel Silo Forming Machine:
First, this spiral steel silo forming machine rolls form 495mm wide, 2mm-4mm thick steel into 365mm wide strips, and then spiral seam locks them together into round silo. And the swage is about 30-40mm wide outside of the silo to reinforce the silo.
