Profile: Proton Engineering Works is a manufacturer and exporter of chemical pharma plant equipments. Our range of products include drum dryers, drum flakers, vacuum pumps, reactors, autoclaves, heat exchangers, filters and distillation units. Our rotary vacuum dryers and rotary dryers offer clean, simple & effective method of drying wet cake, powder & even slurry. This operation is under vacuum and hence it is possible to dry heat sensitive materials at temperature well below 100°C without suffering the problems associated with very long drying periods. The rotary parts are slow in rotating that ranges from 5-15 RPM. The drying done in a rotary vacuum dryer is a form of batch operation. Our pressure sand filters & activated carbon filters are widely used for filtration of the flow of water through a bed of granular media, normally following settling basins in conventional water treatment trains. Our range of filters enhances the filtration and removes any particulate matter that is left over after flocculation & settling. Our pressure sand filters are widely based on two principles such as mechanical straining and physical adsorption.
