Sliding Orbit (Length): 9 m. (The Buyer can lengthen it yourself) Detail Specification ⑴twin-Screw extruder ① control mode extruder and the auxiliary machines are controlled assynchronization ② Number of the Screws 2 ③ Rotating Direction the Screw 20-70 ④ Available working length of the screw ≥1800mm ⑤ Rotating Direction of the Screws same direction ⑥ Speed adjusting mode frequency conversion ⑦ Gear reducer rigid-gear surface low nosie design ⑧ Material of the screws and the barrel 38CrMoAlA ⑨ Temperature controller Brand :RKC,Japan ⑩ Element of electric system Brand :Seimens ⑪ Feeding materials mode AC frequency controllers ⑵Screen Changer device (with hydro-station) ① Heating power :8(2 zones) ② Hydrovalve:import ⑶T-mould ① shape T model,clothes rack type ② Heating zone:5 ③ Motor material :high-grade Alloy-steel ⑷three-roller Calender(horizontal) ① roller material :45#steel ② roller arranging type:horizontal ③ surface rigity:HRC50 ④ surface roughness: ≤Ra0.025 ⑤ roller face:Mirror surface ⑥ drive system: With three individual gear reducer, ABB brand transducer from Switzerland.Available for adjustment both individually and simultaneously ⑸………………….. ⑹…………………. ⑺………………….. . . . Melt Pump Measure System Function: It can make the melt pressure stable and it’s propitious to make the product take shape. (1).Melt Pump ①Gearing Mesh Mode: out-mesh ②Gearing: Adopt the rigidity gear surface. ③Imput power:11 kw (the same with the main motor of the extruder ) ④Rotation Speed of the Melt pump: 85r/min ⑤Control system. (2).Melt pressure Transducer: ①Range of the pressure:350bar ②DC power supply : 7V / 10V ③Melt pressure controller ④Show the pressure before or after change the screen. ⑤Panel can be changed from manual to automatic automatically This production used for produce the new sheet and also can recycle the waste or the bad sheet which be produced well in the first course,its good for saving the material and other energy,this the design in China is very infrequent,this production we have sold to the Ukraine ,got a good commend by our clients.
