For the production of PVC Compound, Plantech provides complete and automated solutions for the storage, handling and dosing of powders.
Plants of fundamental importance for feeding process machines such as Turbomixers or Extruders and for transferring the finished product to the packaging lines or for storage.
The supply of silos includes ladders and walkways, product filling pipes, dedusting filters, safety valves, level indicators and vibrating cone extractors if the product is not easily flowable. When the raw materials come in bags or Big Bags, Plantech provides its own manual or automatic bags emptying stations and Big Bags emptying stations, provided with hoist or spider for direct loading or using forklift truck.
In both cases, the machines may be provided with specific optional devices, such as flat bottom extractors, pneumatic vibrators and fluidisation devices.
The dosing stations used for supplying the additives necessary with accuracy for the formulation of the Dry Blend are created for powders as well as for liquids, using dosing units and weighing scales, while the pre-weighed bags containing the additives which complete the formulation, are automatically fed into the turbomixers at each batch, by means of a special belt.
In plants for production of PVC compound, the choice of handling systems 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 mainly used is the pneumatic conveyor, for the extraction of products from silos and scales for feeding to the weighed cyclone filters upline of the turbomixer or pressurised for filling of the storage silos from the Big Bags emptying stations
