Description

Technical Field

[0001] The utility model belongs to the technical field of rotor scales, in particular to a screening device used for rotor scales. Background Art

[0002] The rotor scale is composed of a powder quantitative feeder, a ring-shaped balance rotor scale, a wind lock device and a microcomputer control part. The powder quantitative feeder feeds the powder into the ring-shaped balance rotor scale, and the rotor scale impeller rotates to make the material flow evenly within the semicircle from the feed port to the discharge port. Since the scale body adopts a balance structure, there is material on one side of the disc-shaped scale body and no material on the other half, causing the scale body to lose balance. The weight of the material is detected by the weighing sensor and sent to the control instrument. At the same time, the detected speed signal is sent to the instrument. After processing, the instantaneous flow rate and cumulative amount are obtained. The flow rate can be adjusted by controlling the feeding speed. This is the working principle and function of the rotor scale.
