Model SR-2A-2


This model is designed mainly for fine powder which can easily make dust and meet high-accuracy packing requirement. Based on the feedback sign given by below weight sensor, this machine does measuring, two-filling, and up-down work, etc. It is especially suitable for filling carbon powder, dry powder of fire extinguisher, and other fine powder which needs high packing accuracy. 


1. Weight sensor is below the tray, fast filling and slow filling based on the pre-set weight, to guarantee the high packaging accuracy.

2. Servo motor does up-down work driving with tray together, the up-down rate can be set randomly, and no dust spills out when filling.

3. With servo motor and servo drive controlled auger, performance is stable, and with high accuracy.

4. PLC control, touch screen display, easy to operate.

5. With handwheel to adjust the height, easy to vary fill weight.

6. Process: put bag/can(container) on the machine → container raise → fast filling, container declines → weight reaches the pre-set number → slow filling  weight reaches the goal number  take the container away manually.
