Extrusion system

Feed device

120L Volume stainless steel hopper, forced feeding system

Barrel

External circulation constant temperature water control, internal barrel there is a replaceable wear-resistantandcorrosion-resistant liner made from 17-4PH H1150 stainless steel

Screw

Screw is composed of wear-resistant and corrosion-resistant bimetallic thread elements,inside the corethere is a soft water circulation temperature control system

Temperature control system

Air-cooled chiller

Using air-cooled dual-system chillers, which are mainly equipped with European、America、Japanese imported compressors, Danfoss and Eco-saving components, as well as high-efficiency evaporators and condensers, the normal temperature water is cooled through the compressor mechanism of the chiller to the set temperature to force the control of the operating temperature of each barrel and screw section of the extruder.

Electronic control system

Touch screen console Plus Vertical control cabinet

Adopt a window-style 10-inch domestic high-end, high-stability and reliable touch screen, plus a PLC programmable logic controller host, to implement precise control of the system, and realize PID tuning linkage of the main motor, screw speed and head pressure. The control operation function and main configuration of the system are as follows:

1. With the screw speed set on the touch screen as the standard, the PLC programmable logic controller controls the inverter to drive the 45kw main motor to realize the interlocking power control of the motor;

2. Control cabinet electrical devices, including contactors, air switches and solid-state relays, all adopt Chinese high-end brands, keeping the stability and reliability of the control system. Meanwhile, it has the functions of under-voltage protection and early warning, pressure protection and early warning, and realizes the protection and early warning function of 5℃~35℃ working temperature set on the control cabinet itself.
