Working Principle

• This quick-release screw feeder relies on gravity feeding (e.g., from hoppers, discharge stations) and can be installed at an incline of up to 30°.
• The product is conveyed from the inlet to the outlet through an Archimedean screw. This heavy-duty screw (with inner shaft) is driven by a directly coupled gear motor. For dosing applications, the motor can be connected to a frequency converter for precise speed and dosing control.
• The screw pitch is specially designed to regulate material flow while preventing product compression. The maximum
  discharge capacity reaches up to 53 m³/h.
