Bolted Hopper Bottom Steel Silos: Self-Flow Unloading, No Material Remaining & Cost Effective
- No additional clearance equipment or manual intervention is required, significantly reducing the difficulty and cost of discharging.
Are you currently facing these storage challenges?
Residue of Materials
The accumulation and residue of materials in the silo need to be manually cleared, which is costly and the materials are prone to deterioration;
Investment Control
It is necessary to balance the initial project investment and the daily maintenance costs in the later stage to achieve the maximization of economic benefits;
Storage Safety
It should be sturdy and durable with good sealing performance to ensure safe storage.
Solution & Benefits
Guangcai Hopper Bottom Steel Silo: Stable & Safe Structure with a balance of environmental protection and economy
The inclination angle of the hopper bottom is designed based on the flow characteristics of the material, allowing the material to slide naturally downward and ensuring that the material is completely discharged during the unloading process, achieving efficient self-flow unloading. It is especially suitable for granular or powdered materials with good fluidity. By adjusting the angle of the cone, it can meet the requirements of the fluidity characteristics of different materials and improve its applicability.
The Hopper bottom design utilizes the effect of gravity to enable the material to slide naturally downward, achieving efficient self-flow unloading. This design reduces the reliance on mechanical equipment, lowers operating and maintenance costs. It effectively avoids the accumulation and retention of materials in the silo, reduces material waste; meanwhile, lowers the risk of deterioration or contamination caused by long-term storage of residues to ensure storage safety. By reducing material loss and energy consumption, it embodies the concept of environmental protection and saves operating costs for enterprises as well, thus achieving high economic benefits.
The hopper bottom part adopts a steel structure force analysis design, combined with high-strength steel sheet materials, effectively disperses the internal pressure of the silo, enhances the overall structural strength, and at the same time ensures the stability and safety of long-term use. The connection between the hopper bottom and the silo body adopts welding sealing technology to ensure that the entire silo body has excellent air tightness and moisture-proof performance, protecting the stored materials from the influence of the external environment.
