For the production of plastic materials, Plantech provides complete automated solutions for the storage, handling and dosing of powders, plants of fundamental importance for the feeding of Extruders and for the transfer of granules to the packaging lines and for storage.
The supply of silos includes ladders and walkways, product filling pipes, dedusting filters, safety valves, level indicators and vibrating cone extractors when the products contained are poorly flowable. In case the raw materials are available in bags or Big Bags, Plantech provides its own manual or automatic bags emptying stations and Big Bags emptying stations, provided with spider for direct filling or with the help of forklift truck.
In both cases, the machines can be equipped with specific optional devices, such as flat bottom extractors, pneumatic vibrators and fluidisation. devices. The dosing stations used for the accurate supply of the additives necessary to the extrusion process are designed for powders and granules, using single-screw and double-screw gravimetric batchers.
In plants for the production of plastic materials, the choice of the handling system is assessed according to the distances to be covered, the type of product to be handled, the flow rates required and the type of process to be served.
The system mostly used is the pneumatic conveyor, for the extraction of products meant for supplying the dosing stations positioned upline of the extruders or pressurised for loading the storage silos.
