Features

Double- Screw Extruder

1.Output：According to the raw material formulation process

2.Screw direction：Parallel and same direction

3.Screw：Spindle with 40 CrNiMoA chromium molybdenum alloy tool steel,  screw thread adopts W6Mo5CR4V2 wear-resisting alloy steel,  hardness is HRC60,with transportation, mixing, shearing, mixer,  kneading and reflux block, building block series components, can combine according to any material recipe, to meet the needs of different extrusion process.

4.Barrel：The 5-section cylinder is made of 45# nitride steel forgings, lined with A301 Wear resistant alloy, hardness is HRC60, via nitriding,  conditioning and ultra fine grinding process,  the surface roughness Ra≤0.4μm,  wear-resisting and corrosion resistance.

5.Heating zone：5 cast aluminum heaters fixed at  barrel,1 heater at handpiece,  each section with 1 kw heating power,  security wind cowl overlied outside.

6.Cooling zone：The entire section of the barrel adopts a soft water circulation cooling system, each segments of cooling water flow rate is adjustable, equipped with self-priming circulating water pump, 304 stainless steel water storage tank, inlet and outlet water pipes and the electromagnetic valve components,etc. Can implement independent temperature control and cooling for each section of the barrel unit

7.Vacuum zone：Water circulation vacuum degassing device, equipped with water ring vacuum pumps, vacuum gauge, regulating valve and other components, forming a non-clogging dehumidification exhaust system

8.Feeding device：Adopting double screw metering type forced feeding, equipped with a horizontal mixer, the feeding is uniform and stable, and it is not easy to bridge. The feeding speed is adjustable by frequency conversion from 0-50rpm, and a sliding rail type fast discharge device is installed

9.Die-head pressure：Dynisco high precision temperature and pressure sensors monitor the temperature and pressure changes of the melt in the machine head, interlock and control the operation of the host, with the overpressure protection function

10.Granulation die head：Cr12 chromium molybdenum alloy head, nitriding  hardness HRC60, strand quantity and granulation  diameter can be chosen,  built-in hinge device can replace the screen rapidly.

11.Reduction gearbox：High speed heavy hard teeth surface gear transmission,  gear reduction and torque distribution box is integration structure, internal transmission parts adopt imported bearing and oil seal,  oil splash lubrication.

12.Drive motor：Precision heavy geared motor, constant torque power output control.

13.Main frame：Overall frame adopts steel welding, firm structure ,out of shape not easily,  at the bottom of the rack configured with mobile brake casters,  convenient to install and move.

14.Safeguard：Safeguard functions include: the melt pressure and host interlock,  overpressure alarm protection; Melt temperature and host interlocking,  to start the outage protection; Feeding with the host interlocking,  carries on the protection of the startup sequence.

15.Electronic control system：PLC programmable color touch screen, man-machine interface operation system, extrusion process can be displayed and monitored dynamically,Including temperature control, driving, pressure, interlocking spreading function.

Water tank

1.Hanging wire device：Four groups of guide roller wheel, can adjust water depth and distance

2.Water level control：Stainless steel water level control valve
