Automatic Feeding Screw Conveyor For Powder With Pneumatic Vacuum Conveying System

Application and introduction

Screw feeder is designed for bulk solids conveying or dosing of powder or pellets into batch weighing station.
Features:

1. Gear motor driven by frequency inverter.
2. Screw with different pitch suitable for bad flowing bulk materials.
3. All parts in contact with products are in stainless steel 304.

The system is designed for the automatic feeding of multiple extruders. The storage and transportation of materials are carried out in closed stainless steel containers and pipes. Some dust removal measures are taken to effectively prevent dust pollution and keep the workshop clean. The control system is controlled by imported PLC, and the main electrical components are imported famous brand products to ensure the long-term, reliable and efficient operation of the whole system. The control system can automatically or semi automatically complete the whole feeding process. The simulation screen can display the operation status of each part of the system in real time through the indicator light, and can flash the alarm for the failure part to attract the attention of the operator. The extruder adopts the combination of vacuum feeding and screw feeding. The silo is equipped with two level meters. When the lower level meter shows that there is a lack of material, the feeder will work automatically to fill the material in the large silo to the small silo. When the upper level meter shows that the material is full, the feeder will stop working and temporarily stop feeding. In order to ensure the normal and continuous operation of the extruder, a 50L small hopper is added above the extruder and a level gauge is equipped respectively. If any one of the six level gauges shows a lack of material, the screw feeder will automatically start to work and start feeding until all the six level gauges light up to show that the material is full, and the screw feeder will stop working; if one level gauge is short of material, the screw feeder will start working again, The whole feeding process runs automatically under the control of PLC.
