Noise Level: ≤70–78 dB(A) ensuring quiet operation.
Protection Class: IP65 for dustproof and moisture resistance.
A ideal Conveyor Working mechanism
The U-type screw conveyor working principle is simple yet effective. Material enters the inlet and is moved forward by the rotating helical screw. The rotational force combined with material friction pushes the bulk steadily toward the discharge outlet.
Feeding: In feeding process The huge quantity of Bulk material enters through the inlet.
Transporting: For transpering things The screw shaft rotates and moving material forward.
Discharging: Her in discharging process Material exits smoothly through the outlet and ready for the next process.
Optional Incline: It Can move materials slightly uphill based on installation angle.
This mechanism ensures continuous, clog-free and dust-controlled material transfer.
