According to the silo capacity and the diameter, the silo bottom can be made into different structure types as following. 

1. Steel cone-bottom:

When the single silo capacity is below 800t and the diameter is below 8. 5m, it can be made into steel cone-bottom type.

Steel cone-bottom is composed of upright columns, annular girder, cone plates, tie pieces etc. The upright columns are made of national standard I-shaped steel and I-shaped steel is one of the most widely used steel types in steel structure design and manufacturing.

It has good structure stability and reliability. Annular girder is shaped by channel steel and it has the function of supporting silo body, connecting columns and bottom plates. The cone-bottom plates are completely prefabricated. The connection screw bolts are GB 8.8 grade standard parts.

All these make installation easy and convenient, and after installation the bottom is really good-looking, endurable, and reliable.

2. Cement cone-bottom:

When the single silo capacity is comparatively big and its diameter is below 12m, its is generally made into cement cone-bottom.

Cement cone-bottom is a concrete-cast inverted cone hopper that framed with reinforce bars. It makes unloading materials automatically.

Cement cone-bottom has a mediate construction Price, but has a long construction period.

3. Half-cone-bottom and flat-bottom:
