CONSTMACH's CS-75 cement silo stands out as a versatile storage solution engineered specifically for the concrete batching plant and block production industries. With its 75-tonne capacity and 58 cubic meter volume, this model addresses the material handling needs of both permanent installations and temporary ground study applications. The silo's design philosophy centers on practical flexibility, offering customers a choice between bolted and welded construction methods depending on their project requirements and site conditions.
The bolted version of the CS-75 delivers significant advantages in terms of transportation and installation. Two complete units can be efficiently shipped within a single 40-foot open-top container or standard truck, which dramatically reduces logistics costs for international projects or remote job sites. This compact shipping configuration doesn't compromise the silo's structural integrity or operational performance. Each component is manufactured using precision laser cutting and drilling techniques, ensuring that assembly on-site proceeds smoothly without alignment issues or time-consuming adjustments. The modular design allows installation teams to erect the silo quickly, minimizing downtime and accelerating project timelines.
Standing at 15,880 mm in height with a diameter of 3,060 mm, the CS-75 features a robust four-leg support structure that provides exceptional stability. The legs are constructed from 219 x 5 mm steel pipes, reinforced with 80 mm NPL corner irons and 20 mm sheet metal supports. This multi-layered support system distributes the full load evenly, preventing any localized stress concentration. The conical section, which facilitates smooth material discharge, is built from 6 mm ST-37 sheet metal and supported by 100 mm steel C-channels. The main body utilizes 5 mm ST-37 sheet metal, while the top cover employs 4 mm material, creating an optimal balance between strength and weight that results in a total silo weight of 6,360 kg.
CONSTMACH has equipped the CS-75 with comprehensive safety and operational features that reflect decades of industry experience. A maintenance platform positioned between the legs provides safe access for inspection and servicing. Both inner and outer manholes facilitate cleaning and maintenance procedures, while roof handrails ensure worker safety during top-level operations. The charging pipe, constructed from 4-inch steel pipe extending up to the silo legs, enables efficient material filling. Roof flanges accommodate the air filter and pressure safety valve, and a dedicated roof gate provides access to the inner manhole. The 300 mm output diameter connects to a cone-mounted butterfly valve for controlled manual cement discharge.
The standard equipment package supplied with the CS-75 includes everything needed for immediate operation: a cement screw conveyor available in custom diameters and lengths, an efficient air filter system, pressure safety valve, top and bottom level indicators for precise inventory management, air fluidization nozzles that prevent material bridging, and a pulse valve system that maintains optimal air pressure. These components work together to ensure consistent material flow and prevent common issues like cement compaction or moisture infiltration.
Surface protection receives particular attention in the CS-75's manufacturing process. CONSTMACH applies a comprehensive three-layer coating system consisting of one anticorrosive base layer followed by two layers of final coat epoxy paint, achieving a total thickness of 140 microns. This protective system guards against harsh environmental conditions and extends the silo's operational lifespan significantly, making it suitable for deployment in challenging climates.
Structural integrity forms the foundation of the CS-75's design. All static load calculations and mechanical stress analyses are performed using ANSYS Workbench CAE software, industry-standard engineering tools that predict real-world performance with exceptional accuracy. These analyses confirm that the silo maintains its structural integrity under full load conditions without deformation, providing clients with confidence in long-term reliability. The CS-75 can safely store 75 tonnes of cement or similar powdered materials while maintaining dimensional stability and operational safety across all weather conditions and usage scenarios.
