Other The structure should enable stable conveying and uniform feeding of rubber materials. The screw speed should have stepless adjustment function and display device, which are the same as the requirements of cold feed extruder. Qualified products comply with the provisions of Article 3.4 of GB10481. The head, body and screw of cold and warm feed extruders can automatically adjust and display the temperature respectively. Hot feed extruder allows manual control. Cold feed extruder should have a head pressure indicator. Comply with design. Check drawings and objects. (1) Check drawings and objects. (2) Measure screw speed according to 3.1 of ZBG 95012. Check drawings and objects. Check design documents and objects. 3.2 Product performance (see Table 2). Quality characteristics.
