Fully Automatic Powder Mixing Weighing Conveying System For PVC Pipe Extrusion
Application and introduction
For large PVC pipe/SPC floor/PVC wall panel 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 system 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 compound to extruder the complete PVC mixing system consists of:
1. Loading station(PVC loader Caco3 loader Recycled material).
2. Pneumatic vacuum conveying system.
3. PVC resin and Caco3 and Recycled material storage silo.
4. Automatic raw material and additives dosing system for mixer.
5. PVC mixing unit.
6. Compound storage silo.
7. Automatic feeding system for PVC extruder.
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 (likehoists ....).
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.
