In the conical twin-screw extruder, the conical screw rotates in the same direction, so that the plastic to be processed enters the barrel, and the conical twin-screw is squeezed into a figure-eight shape in the barrel, which increases the plasticizing time and reduces the plasticizing time. The friction between the plastic and the barrel screw ensures the quality of the plasticization and reduces the energy consumption; because the screw used is tapered, the extrusion performance of the conical twin-screw granulator is maintained.
Through the above technology, the conical co-rotating twin-screw extruder fully realizes the characteristics of large extrusion force, good plasticizing performance, high output and low energy consumption. It has been proved that the conical twin-screw extruder can save energy. 30%-50% or more, it is a novel equipment suitable for extrusion molding of various plastics or rubbers.
Conical twin-screw is a technological revolution in the history of plastic extruders. From a development perspective, in the next few years, replacing the traditional plastic extruders has become the main thermoforming machine in the plastics processing industry. The inevitable trend.
Conical twin-screw plastic extruder consists of extrusion system, dosing device, vacuum exhaust system, gearbox, distribution gearbox, heating and cooling system, screw core temperature control system, electronic control system (including fault alarm system and Torque protection device) and other components. It can efficiently produce pipes, dissimilar materials, plates, sheets and granulation.
The counter-rotating conical twin-screw makes the material flow in a U-shape, which can meet the requirements of material transportation, compression, mixing, exhaust, plasticization and other processes.
