Live screw conveyor bottom for sawdust designed and delivered by BEMA:
Designing of a live screw conveyor bottom requires engineering capabililties. Each application is unique
BEMA has engineering capabilities to assist in clarification of the application. We can based on the agreed design manufacture the application and deliver it to the customer side. When designing live screw conveyor bottoms, you shall always consider how to transport it to the final customer destination. In this process also how you want to install it on-site. Similar application for a live screw conveyor bottom.
A live screw conveyor bottom is designed to extract material evenly from large silos, ensuring a controlled and continuous flow. In this case, the system handles rough sawdust from a 100 m³ silo, providing stable discharge for downstream processes. The solution is ideal for biomass, wood waste and other bulk materials requiring uniform emptying.
The system uses four screw feeders that transport material to both sides of the silo. This design keeps the material level even during emptying and prevents funnel flow or bridging. The gradually increasing pitch toward the discharge end ensures uniform extraction and reduces mechanical stress.
Depending on the application, the live screw bottom can deliver between 40 and 150 m³ of material per hour. Capacity depends on material type, screw design and required flow rate. This makes the system suitable for both moderate and high‑volume operations.
Key considerations include material characteristics, required transport capacity, torque and power needs, filling method, and how the material will be handled after discharge. Documentation requirements and on‑site installation conditions must also be evaluated to ensure a reliable and long‑lasting solution.
BEMA provides engineering support throughout the clarification and design process. The silo top and screw bottom can be manufactured in sections for easier transport and installation, ensuring smooth delivery to the customer’s site and efficient on‑site assembly.
