tion box

The radial bearing of torque distribution system adopts NSK bearing, gear is high speed heavy load hard tooth surface, gear shaft material 20 CrNi2MOA with HRC 58~62

Extrusion system

Feeder

Stainless steel hopper, stainless steel hardened driven screw forced feeding structure in counter-rotating way.

Double-stage barrel

External circulation constant temperature water control temperature, internal replaceable wear-resistant corrosion-resistant stainless steel lining combined barrel.

Double-stage screw

Hardened stainless steel screw elements and some HIP screw elements combine on top-wear position. Inside second stage screw core, a soft water circulation to be designed for strengthening temperature control.

Exhaust system

Vacuum exhaust

A world leading vacuum pump professional manufacturer Germany Busch brand to be equipped, innovative technology of oil-free claw vacuum pump, to ensure a strong, economic, efficient, reliable and mute operating state, with high efficiency, no oil, no contact operation, no maintenance of high-end performance.

Tempera-

ture control system

Accurate tempera-ture control

One air-cooled dual-system chiller is mainly equipped with compressors imported from Europe, America and Japan, Danish Danfoss and American Eco throttle parts, and high efficiency evaporators and condensers. The normal temperature water is cooled to the set temperature through the compression mechanism of the chiller to control the operating temperature of each barrel and screw section of the extruder.

Electronic control system

A touch

control screen plusa

vertical electric control cabinet

A windows 10 inch high-end, high stability and reliability touch screen

made in China to be equipped, with PLC programmable logic controller

mainframe, accurate control of the system, from the main motor of the

firststage extruder to the vacuum pump, andwiththe main motor of the

secondstage extruder, the PID setting linkage control is realized.

Dual-stage control system operation control function and main

configuration are as follows:

1. For upper stage extruder, based on the screw speed set on the touch

screen, PLC programmable logicc ontroller to control the frequency

converter to drive 11kw main motor, to realize the first-stage extruder

interlocking power control;

2. For bottom stage extruder, based on the screw speed set on the touch

screen, PLC Programmable logic controller to control the frequency

converter to drive 18.5kw main motor to realize interlocking power

control;

3. All the control cabinet devices, including contactors, air switches and

solid state relays, most adopt high-end brands of Schneider, pressure

sensor adopts American Dynisco brand, to pursue the stability and

reliability of the control system. The functions of under-pressure

protection and early warning, pressure protection and early warning of

extruder are designed at the same time. The working temperature of 5℃

~35℃set by the control cabinet itself is protected and early warning

function is realized
