What is a cement silo?
A cement silo, also known as a cement tank, is a key component of a concrete batching plant used for storing bulk powder materials such as cement, fly ash, and slag powder. It features excellent sealing performance, strong structure, flexible installation, and easy operation. Cement silos are widely used in ready-mix concrete plants, precast factories, cement product plants, as well as in construction materials, chemical, and grain storage industries.
How do cement silos work?
Bulk cement or other powder materials are delivered into the silo through a pressurized pipeline from a bulk cement tanker.
The dust collector on the top cover filters and discharges excess air to prevent dust pollution.
Materials are discharged through the cone-shaped bottom outlet and conveyed to the mixer via a screw conveyor.
Level indicators continuously monitor the material level inside the silo, with high/low-level alarms to prevent overfilling or material shortage.
If material blockage occurs, the arch-breaking device helps loosen the material to ensure smooth discharge.
Parts of Cement Silos
Silo Body: Cylindrical steel structure composed of a top cover, vertical shell, and conical bottom. The surface is treated with anti-corrosion paint.
Top Cover: Equipped with safety guardrails, feeding port, manhole, and dust collector interface.
Cone Section: Designed for material discharge, typically with a 60°–70° angle to allow smooth gravity flow.
Support Legs/Base: Steel columns that support the entire silo, usually configured with four or eight legs.
Dust Collector: Mounted on the top cover to prevent dust emission during filling and discharge.
Arch-Breaking Device: Uses pneumatic vibration or air fluidization to prevent powder bridging and clogging.
Level Indicator: Detects high and low material levels for intelligent monitoring.
Discharge System: Located at the bottom with an outlet flange for connection to a screw conveyor.
Advantages & Features
Excellent Sealing: Welded and sealed body prevents dust leakage and moisture intrusion.
Sturdy Structure: Made of high-strength steel plates for durability and long service life.
Modular Design: Allows for sectional transport and on-site assembly, ideal for export or space-limited projects.
Customizable: Flexible options for capacity, material, discharge type, and more.
Easy Maintenance: Simple structure for convenient inspection and cleaning.
High Safety: Equipped with ladder, guardrail, safety valve, and level alarm for safe operation.

Main Applications of Cement Silo
Used for storing bulk powder materials such as cement, fly ash, slag powder, and silica fume.
Works together with a screw conveyor to achieve automatic material transfer from storage to mixer.
Ensures continuous material supply for the batching plant, improving production efficiency.
Prevents moisture and caking, extending the storage life of materials.
Usage and Maintenance Tips
Regularly check the working condition of the level indicator, arch-breaking device, and electrical control system.
Avoid overpressure feeding to prevent damage to the silo top.
Clean the dust collector filters regularly to ensure smooth ventilation.
Perform anti-corrosion inspections: repaint any peeled coating areas promptly to prevent rust.
Prevent moisture: ensure the silo cover is well-sealed and the silo body has no water leakage points.
Transportation and Installation
Small cement silos (≤50 tons) can be transported as a whole and lifted directly into place.
Large cement silos (≥100 tons) are usually delivered in sheet form and assembled on-site with bolts.
During installation, foundation anchor bolts must be prepared in advance to ensure the legs are vertically aligned and securely fixed.
After installation, pressure tests, ventilation checks, and function debugging should be carried out to ensure proper operation.
