>>PVC cable compound processing:

General:

In the process of PVC cable extruder, Many PVC cable factory will face these problems: lack of Surface brightness;

Tiny pimple on its surface; Surface fish squamous; Air hole in the granule, etc.

The cause of problem is: machine is not installation and debugging very well; Choosing the wrong extruder.

Nowadays, two-stage compounding extrusion line has been the best choice in processing PVC Cable. This kind of machine is good at

high capacity and good plasticizing.

Processing:

1. After mixing PVC material in the high speed mixer, Using the spiral feeder to feed into the SHJ twin screw extruder.
2. After good compounding in the twin screw extruder, now the PVC material is completely plasticizing and

decentralization, the temperature is about 140-160° C. The final extruding material is molten mass

(the temperature is 130-140°C), which fall into the large diameter single screw extruder directly.

3. Within the lower rotary speed, high pressure and cooling state, The secondary stage Single screw extruder will

finish the extruding and pelletizing. Then the temperature has fallen to 120-140°C. This Air-cooling die face pelletizer process can avoiding cosmid phenomenon .

Cooled by the two cyclone separator system, the granule's temp. is about 35-40°C. Then after Air-cooling extended vibrating sieve, now the granule has fallen to the room temp., which can packing in the silo.

>>Eletrical control parts:

Characteristic:

1. The original imported speed-control device or AC frequency conversion speed regulator insure screw speed high precision and torque output

stability.

2. Temperature use PID regulating mode, double channel control.

3. Digital display melting pressure and melting temperature meter play real time monitor towards the extrusion

parameter.

4. Electric control cabinet structure design refer Siemens, the space is roomy, beneficial to the ventilation and heat

dissipation, maintenance and inspection.

Program-controlled part:

Electrical control system can use imported PLC, temperature control; melt pressure, main machine current and other

imported meter for monitoring, which can intuitively reflect the unit's running. This unit has functions of heating break

line alarm, main/auxiliary equipments failure alarm instructions etc, that can realize comprehensive interlock protection.

This system use button style operation with low failure rate and with convenient maintenance.
