We are Manufacturer, Supplier, Exporter of Dilute Phase Transport Positive Pressure Systems and our setup is situated in Pune, Maharashtra, India. The product enters the convey line, which is at a higher pressure, via a special feeding device, usually a rotary valve airlock, or a venturi. The product is frequently suspended in the airflow, moving at relatively high velocities depending on the particle sizes and densities. The suspended material-air stream is separated at terminal point by means of a filter receiver / cyclone separator, or fed directly into process vessels that are vented to downstream dust collection devices.
In this type of system, the material does not go through the fan / blower. There are two advantages to this. First, the fan wheel does not damage the material. Second, the fan does not experience any wear and tear from the material. These systems generally operate on a continuous basis - product is constantly supplied at the starting point, and arriving at the destination without interruption. This allows this type of system to be easily adapted for dosing and continuous weighing applications.
Applications
Dilute phase pressure conveying is particularly suitable for systems which convey materials at low to moderate capacities over medium distances, from single or multiple sources to single or multiple destinations. These systems are versatile and adaptable for different materials and the low operating pressures allow lower cost pipelines and fittings. Cement, fly ash, food items, resins and dry chemicals are examples of products that can be conveyed successfully using this method.
