Spiral powder batching system

Working principle

When the material is sent from the feeding port to the discharging port through the impeller screw conveyor, the electronic weighing device installed on the screw conveyor (mainly composed of weighing lever, weighing sensor, etc.) detects the weight of the material and generates a piezoelectric signal proportional to the load of the weighing lever. At the same time, the speed sensor installed at the tail of the screw conveyor detects the speed signal of the main shaft of the screw conveyor. These two signals (weight signal and speed signal) are received by the weighing instrument, which processes these two signals and displays the instantaneous flow rate and cumulative weight of the material.

System composition
This system mainly consists of a screw conveyor, scale body, drive device, weighing sensor, speed sensor, weighing instrument, electrical control system, and variable frequency speed controller (optional), which can be extended to PLC control and computer automation management.

System Characteristics
1. Sealed structure to reduce dust emissions;
2. Combining dynamic measurement with spiral conveying of materials;
3. Variable frequency speed regulation runs stably and reliably (optional);
4. Electronic automatic measurement calibration coefficient, automatic zeroing;
5. Tracking of dynamic zero point nonlinear output characteristics;
6. Digital pulse generator provides reliable and accurate speed signals.
