For large scale PVC pipe/profile production factory, Advanced automatic weighing compounding conveying system is essential,
Traditional mixing method is that people weigh and batch material manually, then move the mixed material to extruder also manually, this old way just fit for the small factory, and has many defects:
1. Artificial mixing is easy to make a mistake, because this is a repetition work, so worker is tired easily. the weighing precision is not assured.
2. Labour intensity is large, human cost is high from long term view
3. Chemical raw material harms the worker’s health.
In order to solve these problems, our company design this PVC automatic mixing weighing conveying system which the computer can automatically control weighing and batching, and feeding to extruder.

The complete pvc extrusion line consists of:
1. Loading station(PVC loader+Caco3 loader+wood powder loader)
2. High pressure blow tank
3. PVC/Caco3/Wood powder storage silo
4. Vacuum conveyor with automatic weighing system
5. PVC Mixer Unit
6. Mixed material storage silo
7. Tube chain centralized feeding to extruder
