Gravimetric Doser

The gravimetric doser is a vital piece of plastic auxiliary equipment, designed for the precise automatic dosing of color masterbatch and additives. With a motor gear ratio of 38:1 and screw diameters available in 12, 16, 20, and 30 mm, it offers different models to provide output rates ranging from 0.04 to 60 kg/hr, catering to diverse production needs. The doser supports extruder mode, allowing for easy synchronization with the extruder screw speed to ensure a stable color addition ratio. Additionally, it can be paired with a positive pressure air loader for automatic material replenishment, ideal for applications with small additive consumption.
