1. Single screw main machine:
1) Screw diameter: ¢180mm, L/D: 28:1,
2) The screw are connected to the gear box through involute spline;
3) The screw material: 38CrMoALA, nitrogen hardening. The hardness of the surface is HV 950-1050, deep layer: 0.5-0.7 mm; the barrel material: 38CrMoALA, nitrogen hardening. , the hardness of the surface is HV 950-1050; deep layer: 0.5-0.7 mm;
4) Main motor power: 100 kw, (A/C) speed is regulated by Italy regulator; screw speed 17-84rpm;
5) Barrel heating: cast- Aluminum heater. Heating power: 60 kw, divided to 7 zones, The machine head is a zone and others are 8 zones. Cooling by blowing way;
6) Adopted 250 model gear box. The speed is controlled by main transmission box with high torque, and hard gear face, using SKF imported bearing, material of the gear axial is 20CrNiMo, by immerse carbon and heating treated, HRC60-63;
7) Adopted automatic screen changer, operating easily;
Interlock control 1). The extruder motor is set up the current overload to achieve chain shutdown protection with electric control cabinet. 2). The control system of main machine motor is interlocked with control system of feeder motor as a way of protection mutually. 3). Transmission gearbox and lubrication system are interlocked for protection. 4). The extruder is set up the pressure overload to achieve chain shutdown protection with electric control cabinet. 5). The main motor is connected with the nylon pin of transmission gearbox so as to cut off the nylon pin when torque is overload. Photo of YD180 machine
