PIN-BARREL COLD-FEEDING RUBBER EXTRUDER
Usage:
It is mainly used for continous extrusion of various of rubber profiles and rubber feeding for calender.
Features:
1. The barrel is composed of several zones. The spiral slots is made in the feeding zone of barrel to increase the feeding capacity working together with feeding rolls, different number of pins are fitted which enhance mixing and plastic capacity for extrusion material in the plasticity and extrusion zone, .
2. The screws and barrels are made of high quality alloy steel with nitrogen hardening which makes it more wear-resistant and more corrosion protection.
3. The temperature each zone may be automatically probed and controlled by hot water circulating device with good sensitivity, and can be adjusted according to requirement of process.
4. The extruder is driven by a change frequency motor or D. C motor, which achieve continuous and smooth speed regulation.
5. For adopting of higher efficiency screw and pin-barrel, the extruders have better mixing and plasticating result, higher extrusion capacity, and lower temperature for rubber, the output of production and the quality of product are raised.
