This system includes automatic feeding dosing mixing system, vacuum conveying system, etc. it is suitable for automatic weighing, mixing and conveying of all powder and particle materials to plastic extruder. It has the advantages of high automation, no dust and high efficiency; Suitable for PVC pipes, Window profiles, SPC floor and other PVC industry customers.
PVC Automatic Compounding Weighing Feeding System For Extruder Line Mixing machine
Application and introduction
For large PVC pipe/SPC floor 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.
Automation of bulk material handling systems
Automation and storage, automation and discharge:
The storage of large bulk solids quantities is realized in silos, big-bags and containers, equipped with automatic discharge aids for a safe extraction of the required product amount from the container. In case of larger capacities the bags emptying is made automatically; at smaller discharge capacities the manual discharge process is usually supported by mechanical devices (like hoists ....).
Automation and conveying:
The application of automation technologies in the field of bulk solids transport - comprising both mechanical systems (screw conveyors, bucket elevators, chain conveyors...) and also pneumatic systems (conveying under overpressure and by vacuum, fluidized bed chutes...) - has a very strong impact on production and productivity. It allows to transport even very large bulk quantities in a reliable and safe manner over great distances without human intervention.
Automation and metering, automation and weighing:
In the field of metering and weighing the automation allows higher metering accuracies and has - besides of a productivity increase - mainly an impact on the product quality. Of great importance are the production records and batch protocols recorded and filed by the recipe management system.
Raw material preparation is a necessary and very important step in a PVC extrusion process.
what is the targets we want to achieve:
A: Improve the finish product quality
(and as a consequence the profit margins of the product) Definition of quality: A product is constantly produced without any variation of the specific characteristics the product need to have for fulfilling the final task of the product's application.
B: Improve the prestige of PVC processors
With a state of the Raw Material Handling System the ENVIROMENTAL CONDITIONS inside and outside the production plant(Dust, Noise, Steam, Smells, Vibrations) are improved easily and therefore the prestige of this industry as well as.
C: Minimize labor cost since the introduce of automation processing
A modern material handling plant for PVC processing should include below sections and units:
1. Bag empty of raw material
2. Loading raw material into the storage silos
3. PVC and additives dosing and weighing system
4. Mixing machine or heating and cooling mixer
5. Dry Blends material storage
6. Extruders' feeding system
7. Central de-dusting system
8. Central electrical controling system
