Caco3 Filler Masterbatch Extruder

The machine model is mainly determined according to the customer’s output. The L/D of the twin screw extruder is the higher the better. It is usually required to be more than 40 with a high cost-performance ratio. Generally, the 52mm, 65mm, and 75mm twin screw extruders are more popular with customers. The triple screw extruders of 52mm, 65mm and 75mm have a higher output and better mixing effect than the twin screw extruders of the same model.
