Time：
2018-08-22
Technical parameters of the pin‑type cold‑feed extruder: Screw diameter: 90 mm; Main motor power: 45 kW; Production capacity: 100–300 kg/h; Screw speed: 50 r/min. Structural features of the pin‑type cold‑feed extruder: 1. The barrel is a segmented design; the feeding section features helical grooves that, in conjunction with side pressure rollers, enhance feeding performance, while the plasticizing and extrusion sections are fitted with varying numbers of pins; 2. Temperature in each zone is automatically controlled in stages by a hot‑water circulation system; 3. This machine offers excellent plasticization, high extrusion output, low die‑temperatures, and smooth operation; 4. The screw is manufactured on an imported CNC milling machine…
