Product advantages

Hengao Twin Screw extruder has many advantages,which focus on feeding system,driving parts,transmission parts,screw rpm,screw design,barrel composition,electrical control sytem,pelletizing system,etc.

1.Feeding system:Hengao has developed the volumetric feeder and continuous gravimetric automatic feeding system.On volumetric feeder system,we use new design type feeder which avoid the powder leakage shortage;The gravimetric feeder adopts Siemens PLC and international brand load cell,through PROFIBUS toachieve close-loop control,so that it increase the accuracy of feeding,also realized the industry automation.

2.Driving parts:Used best brand motor,AC or DC are both avaiable.Also ABB or Siemens motor as optional.

3.Transmission system:Gearbox is used tri-axis structure,which combine reducyion and torque distribution together.All bearing are used SKF or INA product.it has Oil-immerge lubricating system and multi-point enforcing lubricating system.It also provides alarm function when low oil position or over pressure happens.

4.Screw rotating speed:Currently,we have standard twin screw extruder from 400-600rpm. We will suggest customer to use suitable rpm extruder accorder processing material.

5.Screw combination:All screw parts are all segments parts,the L/D can be from 28~60.Customer can easy to change the screw design to meet different polymer processing,so that we can use one machine for different purpose process.The screw parts are made of high-speed tool steel.Also with so many years experience,we designed different type kmeading elements,mixing elements,gear disk etc.

6.Barrel structure:according different customer process,we can supply the integrate alloy liner barrel or separate alloy liner barrel.The integrate liner is the international last-design for barrel,which casting the liner complete piece with spcial wear-resistance alloy material.Compare with traditional separate alloy liner,it increases the wear-resistance and get longer life for the barrel.

7.Electrical control:According AC motor and DC motor,there are two control ways.For DC motor,we use Eurotherm regulator.For AC motor,ABB/Mitsubishi/Yaskawa inverter are available.The whole electrical control system can use PLC or PCC industrial automation system.It has over-current,over pressure,over load alarm and protection system which ensure the machinery run properly and safety.

8.Machinery base :It has stainless steel cover on barrel for production.The water tank,vacuum tank which can separate with main extruder for easy maintenance.

9.Pelletizing system:Multi-type pelletizing system are optional,we can supply Strand pelletizer,air-cooling pelletizer,water-ring hot cutting pelletizer,eccentric water-fog pelletizer according the processingt material and technology requirement.
