Tubular ribbon flight screw feeder for lime feeding

Experience uniform material flow and precise dosing with this specialized screw feeder designed to handle hydrated lime and bulk solids efficiently in high-speed continuous operations.

Ensures Consistent Dosing and Conveying of Lime

The Tubular Ribbon Flight Screw Feeder PR from WAMGROUP stands out due to its specialized ribbon flight design tailored for precise lime dosing applications. This feeder ensures uniform discharging from silos into dissolvers or micro-feeding devices, catering to industries like chemicals, construction, and food processing. With outside tube diameters ranging from 70 mm to 168 mm, it offers flexibility in integration with various systems. The unit features a direct-mounted WAM gear reduction unit with optional mechanical variable speed control for energy-efficient operation, reducing energy consumption and wear on components. Feeding rates range between 70 to 4,500 liters per hour, making it suitable for both small and large-scale operations across continuous high-speed processes. Constructed with durability in mind, it boasts corrosion-resistant materials ideal for handling hydrated lime and other bulk solids. Maintenance is simplified with standard inspection hatches and a maintenance-free end bearing assembly, ensuring minimal downtime in busy production environments.
