A fully Automatic Vacuum Hopper Loader is a device used to automatically load plastic resin, pellets, or other granular materials into processing equipment, such as injection moulding machines or extruders. A fully Automatic Vacuum Hopper Loader consists of a vacuum generator, a hopper, a control panel, and a conveying hose. The vacuum generator generates a vacuum that pulls material from the hopper and through the conveying hose, delivering it to the processing equipment.
