Twin-screw extruder screw
The extruder screw, as the core component of the twin-screw extruder, directly determines the production efficiency and service life of the entire machine.The screw produced by Jinan Datong has six core advantages: ultra-high temperature resistance, ensuring no deformation under high-temperature conditions; high wear resistance, with strong friction between the two screws for long service life; high strength and toughness, capable of withstanding large torque and supporting high-speed operation; corrosion resistance, suitable for processing various materials; excellent machinability, allowing precise machining of the screw's peripheral edges; minimal residual stress after heat treatment, slight thermal deformation, and stable and reliable dimensions.The screw material undergoes strict selection and heat treatment processes to ensure long-term stable operation in harsh environments with high temperature, high corrosion, and strong wear.In addition to supplying complete production lines, the company also provides original spare parts such as screws, barrels, and molds year-round, with guaranteed quality and competitive prices. Welcome to inquire and place orders.
The core position in a twin-screw extruder belongs to the screw. The twin-screw extruder is to the extruder what food is to humans, and the characteristics of the core screw are crucial to the entire extruder. As known from the production of extrusion machinery, the screw operates under high temperature, corrosive, and severe wear conditions while performing high-torque work, requiring the screw to have the following characteristics:
1) High resistance to extreme temperatures, ensuring the screw does not deform under high-temperature environments.
2:) Wear resistance. During operation, the extruder works through the strong friction interaction between two screws, ensuring a long service life.
3) High strength, hardness, and toughness, capable of withstanding high torque and operating at high speeds.
4) Corrosion resistance: Regardless of the material, it has a certain degree of corrosiveness, so the requirements for the screw material are very high.
5) Machinability: The peripheral edges of the screw have good cutting and processing capabilities.
6) Resistance to deformation: The screw material after heat treatment has low residual stress and minimal thermal deformation.
In addition to long-term factory-direct supply of various extruded feed and extruded food production lines, Jinan Datong Machinery Equipment Co., Ltd. also provides various spare parts for extruders, such as screws, barrels, molds, etc., to manufacturers. Welcome to inquire and order.
