Enclosed helical screw mechanism for volumetric feeding of fine or semi-moist materials.
● Design: Variable pitch flights, shafted or shaftless options, dust-tight casing
● Function: Precise dosing with minimal spillage or dust generation.
● Applications: Silica fines, clay-rich sand, powders, etc…
Our Screw Feeder is a precision-engineered system designed for controlled, dust-free discharge of fine powders, semi-moist materials, and cohesive bulk solids. While designing a screw feeder every application is a unique on the basis of customer’s requirements. Our Screw Feeder is Ideal for silica fines, clay-rich sand, and industrial powders, it ensures consistent feed rates and seamless integration with hoppers/bins, and downstream equipment.
