When high-capacity concrete batching operations demand reliable cement storage, the CONSTMACH CS-300 bolted cement silo delivers industrial-grade performance with practical engineering. This 300-tonne capacity storage solution addresses the critical requirements of large-scale concrete production facilities where consistent material availability directly impacts operational efficiency.
The CS-300 stands 18.45 meters tall with a diameter of 5.14 meters, providing 230 cubic meters of storage volume calculated for standard cement density of 1.3 tonnes per cubic meter. The silo's six-leg support structure uses 273mm x 10mm steel pipes, reinforced with 80mm NPL corner irons and 20mm sheet metal components. This configuration distributes the substantial 22,000kg structural weight while maintaining stability under full load conditions. Between these legs, CONSTMACH incorporates a maintenance platform that facilitates routine inspections and servicing without requiring specialized access equipment.
The body construction employs ST-37 grade sheet metal in varying thicknesses—8mm, 6mm, and 5mm—strategically positioned according to structural stress requirements. The conical discharge section uses 8mm ST-37 sheet metal supported by 200mm steel C-channel framework, ensuring controlled material flow during cement extraction. This tapered geometry works in conjunction with air fluidization nozzles to prevent bridging and maintain consistent discharge rates. The top cover, manufactured from 5mm ST-37 sheet metal, includes flanged openings for the air filter and pressure safety valve, while a dedicated roof gate provides access through the inner manhole.
Material handling infrastructure integrates directly with the silo design. The 4-inch steel charging pipe extends to leg height, allowing bulk cement delivery trucks to connect and fill the silo efficiently. At the discharge end, a 300mm diameter outlet accommodates a cone butterfly valve for manual cement release when automated systems require bypass or maintenance. Both inner and outer manholes provide inspection access, and the roof section features safety handrails meeting industrial safety standards.
CONSTMACH supplies each CS-300 complete with operational equipment rather than as a bare structure. The package includes a cement screw conveyor customized to project-specific diameter and length requirements, along with pulse valve controls for automated operation. Top and bottom level indicators monitor inventory status, preventing overfilling while alerting operators when replenishment becomes necessary. The pressure safety valve protects against overpressurization during pneumatic filling, and the air filter captures particulate emissions to maintain environmental compliance.
Manufacturing precision defines the CS-300's assembly process. All 191 components undergo laser cutting and CNC drilling, creating bolt holes and connection points with dimensional accuracy that simplifies field installation. This prefabrication approach means construction teams can erect the silo on-site without specialized welding or fabrication equipment, reducing installation time and labor costs while maintaining structural integrity.
Structural validation doesn't rely on empirical methods. CONSTMACH performs comprehensive static load and mechanical analysis using ANSYS Workbench CAE software, simulating real-world stress conditions before any metal gets cut. These calculations confirm the silo maintains structural stability under maximum 300-tonne loading without deformation, accounting for cement weight, wind loads, seismic factors, and operational dynamics. This engineering rigor provides documented assurance for projects requiring certified structural compliance.
The protective coating system extends operational life in industrial environments. Following surface preparation, technicians apply one layer of anticorrosive primer followed by two layers of final coat epoxy paint, achieving a total thickness of 140 microns. This multi-layer approach creates a barrier against moisture, chemical exposure, and atmospheric corrosion that threatens bare steel in cement handling facilities.
For concrete producers evaluating cement storage capacity, the CS-300 addresses both immediate operational needs and long-term reliability requirements. The bolted construction method offers installation flexibility while the engineered design provides performance certainty backed by structural analysis. CONSTMACH has developed this model specifically for applications where cement availability cannot become a production constraint.
