400-1200kg/h two-stage (twin screw/single screw) compounding and granulating machine for PVC, XLPE, halogen-free flame-retardant cable materials, shielding materials, high-concentration carbon black

The first section is a high-speed co-rotating twin-screw mixer, and the second section is a low-speed single-screw extruder. The two are arranged in a T-shape to form a two-stage composite unit.

Principle characteristics and uses:
1. Combine the advantages of co-rotating twin screws and single screws to complement each other. Twin screws force conveying, efficient plasticizing mixing and shear dispersion, no head back pressure reflux, avoiding high shear overheating; single screw high pressure extrusion, but low speed and low shear, also avoids overheating contradictions.
2. The combination of twin screws and single screws decomposes the process functions, increases independent operating variables, and is conducive to the step-by-step optimization of each process; improves efficiency and production capacity.
3. Widely used in various heat-sensitive material systems and large-capacity devolatilization operations, such as: PVC, XLPE, halogen-free flame-retardant cable materials, shie
