For the preparation of chemical compounds, Plantech provides complete automated solutions for the storage, handling and dosing of powder or granular products.
Plants of fundamental importance for feeding process machines such as reactors or mixers and for sending the finished product to the packaging or storage lines. The supply of silos includes ladders and walkways, filling pipes, dedusting filters, safety valves for overpressure, anti-burst membranes in the case of potentially explosive powders, level indicators and vibrating cone extractors for poorly flowable products.
When 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 which can be provided with hoist for direct loading or spider for loading using forklift truck. In both cases, the machines may be equipped with flat bottom extractors, pneumatic vibrators and fluidisation devices.
The dosing stations, useful for supplying the additives necessary for the formulation of the required chemical compounds are designed for powders and for liquids, using volumetric or gravimetric batchers and weighing scales. In plants for the preparation of chemical compounds the choice of the handling system is assessed according to the distance to be covered, the type of product to be handled, the flow rates required and the process to be served.
The system mainly used is the pneumatic conveyorused for the extraction of products from silos and from scales, for supplying the weighed cyclone filters upline of the reactors, and under pressure, for loading the storage silos by the automatic bags emptying station.
