Machine:

Kneader (Banbury) + Single screw extruder = Kneader (Banbury) Single Extruder Compound Machine.

Processing Technology:

Kneader banbury ---bucket conveyor ---Conical twin screw force feeder---single screw extruder compound---Air Cooling Hot Face Cutting System/water ring cutting system---Silo

Introduction:

Kneader (banbury) can put all the compounding mixing them together by batch，like kneading flour again and again by inner batch.

After all the materials are mixed by kneader(Banbury), the large HOT and SOFT mixed materials will be fed from the kneader through Bucket conveyor to the cone double force feeder, and then pushed into the single-screw extruder, the materials are homogenized again and passed through the die.

Advantage：

The kneader (Banbury) adopts an automatic temperature and time control system, which is accurate, simple and easy to operate, and the mixing can achieve the best uniform dispersion effect.

The mixing tank is tiltable, and the mixing shaft is leak-proof  and adopts a dry mechanical shaft seal to make it easy to clean and change colors.

The pressurized kneader(Banbury) can not only ensure the mixing characteristics and quality, but also prevent environmental pollution.

The kneader(Banbury) of the internal mixer is made of high-grade alloy steel, and the surface is treated with wear-resistant steel. The surface is electroplated with hard chromium and has excellent wear resistance.The functions of the upper and lower extruders are separated, and the operator can perform a more flexible and predictable mixing process and temperature control.

The Conical Twin Screw Force Feeder is a jacketed welded structure, which can be cooled by water or heated by oil/hot water/steam to adjust the temperature to meet the process requirements of different materials. The feeding conical twin-screw adopts a variable diameter and variable torque convergent structure to enhance the extrusion capacity of the material. At the same time, the flat nozzle head is used to increase the density of the extruded material and the surface is smooth.

The diameter of the single screw is relatively large, when the material passes through the single screw, the pressure of the material can be released to the maximum, and the material is uniformly and stably extruded through the large screen changer in the head to ensure the long-term stable quality of the material.
