Bolted Silo

A bolted steel silo（also called bolted cement silo) is a bulk material storage device assembled from steel plates. Its components are prefabricated in a factory and transported to the site for overall assembly through bolt connections. This type of silo typically has a conical bottom, with the top of the silo body closed and a discharge cone at the bottom, suitable for storing and using various powdered or granular materials, especially for the cement storage.

Main Technical Parameters for Bolted Silo:

Storage capacity range: 50 tons to 2,000 tons (based on cement)
Diameter range: approximately 2.9 meters to 21 meters (customized according to storage capacity and project requirements)
Wall thickness: 4mm to 10mm (calculated based on pressure bearing and structural design)
Structural form: adopts a flat plate with edge flange folding design, with steel plates assembled into a whole through bolts
Applicable materials: cement, fly ash, gypsum powder, dry mortar, sand, mineral powder, lime powder, grain, etc.
Connection method: horizontal and vertical flanges are staggered and spliced to act as reinforcing ribs, enhancing overall stability and load-bearing capacity

Application Industries and Scope

Due to its strong versatility and wide adaptability, bolted steel silos can be applied to almost all industries involving bulk material storage. Its main application industries and scenarios include:

Building materials industry: such as concrete mixing plants and cement production plants, for storing raw materials like cement, sand, and fly ash;

Power industry: centralized storage and secondary utilization of by-products such as fly ash and desulfurized gypsum from thermal power plants;

Metallurgy and mining: temporary or long-term storage of mineral powder and lime powder required in the steel smelting process;

Chemical industry: suitable for reserving and allocating granular or powdered chemical raw materials;

Grain storage: for storing grain materials such as corn, wheat, and soybeans, especially suitable for temporary or emergency storage;

Ports and docks: as transit warehouses or temporary storage points, facilitating rapid deployment and subsequent disassembly and transportation.
 

Especially in scenarios where storage capacity demand fluctuates greatly or project cycles are short, the flexibility advantage of bolted silos is particularly prominent.

Features and Advantages of Bolted Silos

 

Modular design, easy installation

All components are prefabricated in a standardized manner in the factory, requiring no large-scale welding operations on site. Assembly is completed solely through bolt connections, shortening the construction period by more than 50%, which facilitates quick commissioning and capital recovery for the owner.

 

Significant cost advantages

Transportation costs are reduced through modular transportation, and the short construction period lowers labor and equipment costs. Additionally, simple later maintenance reduces overall usage costs.

 

High strength, stable structure

The flange connection forms a longitudinal and transverse reinforcing rib structure, providing good wind and seismic resistance, suitable for various harsh natural conditions.

 

Good sealing performance

The sealing strip can withstand high temperatures of 200°C, with a reliable and effective sealing structure.

 

Flexible disassembly and reusable

Compared to traditional welded silos, the bolted structure can be disassembled, transported, and reassembled at any time, making it particularly suitable for temporary construction projects or multi-site usage needs.

 

Environmentally friendly and safe

The entire construction process involves no open flame operations or on-site welding, with minimal dust and noise pollution, aligning with modern green construction concepts.

 

Easy to expand and upgrade

Due to its flexible structure, the design can be adjusted in size or equipped with additional facilities at any time according to the type of material and capacity requirements, achieving personalized configuration.

 

Installation Technology

The components of bolted steel silo are pre-fabricated in our factory with many connecting points, which including vertical splicing points and horizontal points. All sides of each piece of steel silo are connected by bolts. SRON engineering team will consider the wind speed, seismic activity and temperature of the silo installation site, so as to ensure that the thickness of the silo sheet, the strength of the bolts and support legs could meet the requirements of safe use.

Bolted steel silos, with their rational structure, efficient construction, flexible use, easy maintenance, and green environmental protection advantages, are becoming an important choice for modern industrial material storage systems. Whether in temporary project deployment, remote material transfer, or large-scale storage systems at fixed bases, their performance is outstanding.

With the continuous advancement of industrial manufacturing technology and the deepening promotion of environmental protection concepts, bolted steel silos will play a role in more industries and scenarios, helping enterprises achieve more efficient, intelligent, and environmentally friendly production and operation goals.
