Spiral Silo

Spiral Silo Introduction

The spiral silo is profiled by the special silo profile machine. The silo structure is mechanically integral whole without any holes, bolts and screws.

• Materials: By hot galvanized steel plate 275g/m2, 340g/m3 or 600g/m2, with strong anti-corrosion performance, life-long no need painting.
• Application: For its perfect sealing performance, it is ideal silo for storage of cement, fly ash, mineral powder, water and oil.
• Diameter Range: 4m-25m
• Silo Cylinder Height Range: 6m-25m

Spiral Silo Features

• Integral Intensity and Long Life

  While constructing, feed the coil sheet with certain width into the profiling station, making an confined encircling spiral protruding strip of 30-40mm in width around the silo body. The thickness of the strip is five times thicker than the basic coil sheet, strengthen the silo body in load-bearing capacity, also strengthen the silo in the structure.

• Good Gas-tightness and Wide Application

  The spiral folded edge is of five-layer spiral steel plates with seal gum embedded into spiral crimping seams which ensures excellent silo gas-tightness. The spiral folded silo can store granular, powder material, also meet the requirements of fumigation and deinsectization. Besides, it can also store liquid material, for two kinds of different material, the silo construction equipment can realize double layer bending.

• Short Construction Cycle and Low Expenses

  As the silo is manufactured full auto by the special equipment which runs at speed of 300m/h, the construction of the silo is very fast, and investment returns fast.

• Economizing on Space and Light Weight

  The silo height and diameter is optional with a wide range. The distance between two silos can be minimized to 500mm to make the most of available space and reduce area occupancy. Also the weight of the silo is only 1/6 times of the concrete silo with the same capacity, largely reduce the base structural load and cost.
