Screw weigh feeder

The SN screw weighing feeder is specially designed for powder and small particles conveying between two points. Essentially, the advantage is obvious, it will not change the accuracy of transmission or get hurt to particles.

Unique electrical automatic calibration, captive chai calibration

【Particle size】: 30-50mm
【Productive capacity】: 2.2-110T/h
【Application Area】:Suitable for continuous conveying of powder, granular and bulk materials and controlling the amount of material.
【For the material】:cement、 The fly ash、 Slag powder、 Raw meal powder、 Pulverized coal.


Leakproof structure, reduce dust emissions.

Small clearances between vital parts, about 0.5~1.0 mm.

To overcome chip overflowing from went and avoid getting materials from the gap between mandrel and tube.

Dynamic measurement and screw conveyer in combination.

Good variable speed performance.

optical-electricity encoder velocity measurement, to ensure that the speed signal accurately



When material is conveyed through screw from inlet to outlet, the material weight can be detected by the lode cell on the electrical weighing device under the conveyor and a signal in proportion to the material weight will be generated and transmitted to the controller. Meanwhile, the speed can be detected by the speed sensor installed on the tail pulley and a signal is also generated and transmitted to the controller. By multiplying the weight signal and the speed signal, the instantaneous flow value and total accumulation can be calculated. The control system compares the actual flow signal with the set flow signal and then regulates the output signal through PID to adjust the feeding speed dynamically and thus to realize the continuous feeding.
