The system has following features :

• The material inlet valve provided with the system has a special inflatable rubber seal which is inflated with the help of air pressure on closure of the inlet valve, thus eliminating any chance of air leakage from the transporter top ensuring a 100% sealing at the vessel inlet.
• In our standard equipments & design range bends provided are of converging – diverging type i.e. wherein bend area decreases (thus thickness increases) at the segment outlet, which keeps the material floating and unsettled, thus eliminating the chances of choking in the bend section.
• The transporter is fitted with fluidizing nozzles, which produce a swirling air phenomenon, thus helping in prevention of bridging problem from fine power & adhering problem by hygroscopic elements.

Why dense phase?
By definition, dense phase pneumatic conveying simply means using a small amount of air to move a large amount of bulk material In closely associated slugs through a conveying line, much like extruding. Unlike dilute phase conveying systems that typically use larger amounts of air to move relatively small amounts of material at high velocities in suspension, dense phase offers the enormous advantage of efficiently pushing a much denser concentration of bulk solids at relatively low velocities through a conveying line.

Operating principle :  Dense phase pneumatic conveying pump also named conveying warehouse pump.

Sending system operating modes: materials in the storehouse are into storehouse pump under gravity, during this time, the discharge valve and the intake valve is closed while Pneumatic sealing valve, close calve and exhaust valve open, so ensure the material into the storehouse pump smoothly. Level indicator send electrical signals to PLC controller when the materials reach a certain position in pump, then PLC controller convert electrical signals into valve signal, at the same time, exhaust valve closed, sealing valve, closed valve, vent valve open, after the pressure in storehouse reach a certain extent, signal is sent to PLC controller by pressure transmitter, with that send to discharge valve after PLC convert it into electrical signals. Open the discharge valve, materials into pipe with low flow, high density by air flow. Period finished, pressure in storehouse pump and pipe drop to zero.

Our different modular families of Vacuum Conveyors for the Pharma, Chemical and Food-Industry allow customized modifications of all conveyors regarding the individual application. Even critical materials can be conveyed safely and adapted conveyors can be used for hazardous applications like inside explosion areas or with highly toxic materials. Most of our conveyors are used in applications with conveying capacities from 100kg/h upto 3t/h, where the conveying distance is up to 15m far and 10m high. Realized systems have up to 12 t/h capacity and work with conveying distances up to 80m far and 35m height.
