The application range of rubber screws in rubber cold feed extruders is also an important aspect of their specifications. Different specifications of screws are suitable for different types of rubber materials and extrusion processes. For example, certain screws are suitable for a wider range of materials, including chloroprene rubber, natural rubber NBR, EPDM, SBR, etc. Materials such as silicone rubber, fluororubber, nitrile rubber, etc., while others may.
At that time, rubber screws were widely used in the production of rubber products such as tires, shoe materials, wires and cables, materials, and seals. The diameter of rubber screw is one of its core specifications, and screws of different diameters are suitable for rubber extruders of different sizes and types. For example, the diameter of the screw may be 20mm, 30mm, 250mm, or even larger. These screws with different diameters can handle different types and yields of adhesive materials, including 45mm, 65mm, 90mm, 120mm, 150mm, and 200mm
In addition to diameter, aspect ratio is also an important specification for rubber screws, which indicates the ratio of screw length to its diameter. The aspect ratio is usually between 25 and 36, depending on the design of the screw and the requirements of the extruder.
The maximum speed and thrust are also important components of rubber screw specifications. The maximum speed determines the rotational speed of the screw in the extruder, while the feed rate reflects the amount of rubber material that the screw can push per unit time. These parameters collectively determine the production efficiency and output of the rubber machine.
