PVC Automatic Compounding And Feeding System

PVC Automatic Compounding And Feeding System


PVC automatic compounding and feeding system mainly used for PVC powder material conveying,negative pressure,positive pressure can be used(dilute phase, dense phase),metering(main material,additives),mixing,centralized storage;according to situation on sit,the pipe chain,negative pressure or screw conveying can be used,the material is assigned to each machine hopper.The whole process is centrally by PLC,and centralized monitoring on the host computer.


SHL-W series Horizontal Mixer




Mainly include following process of SPC flooring mixing system:

1.PVC resin weighing system
2.additives weighing
3.little material weighing
4.liquid material feeding
5.mixing tool can be designed according to different application
6.storing and conveying system
7.feeding into extruder

It is used in mixing,stirring,drying,coloring of plastics,rubber,chemicals for daily use.It is an ideal advance equipment of producing plastic board.pipe,profile and degradation plastics.

We adopt foreign advanced technology in making mixer,which adopts the vacuum mixing principle.The electric meters all adopt imported famous brands and adopt PLC controlling,which has character of high automation,quick mixing,the blade is precisely cast of stainless steel and treated by dynamic and static balancing.Especially,the blades of cooling machine adopt the advanced spiral stirring structure,which avoid dead angle,and with the feature of quick cooling,thoroughly discharging,high efficient of mixing.


1.Automatic feeding system –unmanned

SPC PVC automatic mixing solution is professionally designed for PVC or WPC plastic industry in mixing workplace.This set of confined system is used for automatically measuring,feeding,mixing,dosing to the extrusion of variety powders,particles and liquid.

2.Central dust collecting system-dust-free

The mixing workplace of PVC and WPC plastic industry is mass dust and workers are mobile.In the use of centralized feeding system we choose to connect the dust collection with the dust occurring outlet,so that collecting and recycling use of this part.Dust-free workshop is not only the modern industrial standard but also can save a lot of material and labor.

3.The central control system—intelligenize

Intelligent control system is to avoid mistakes and loss caused by manual operation,such as the wrong formula of feeding raw material lead to batches unqualified products and wast of secondary processing.The lack of automatic dosing function would result in short filling,which is the damage to screw and extruder. The key point is that lack of an automatic system to calculate materials based on production.


Suitable for plastics,rubber,chemical and food industry,for powder or granulate material blending,coloring and drying.Typical application includes:Production of PVC dry blend,filling and modification of plastics,pre-mixing of compounding process and premix of Wood-Plastic Composites.
