We use it for little abrasive products with low wear and brake with a transport speed oscillating between 15 and 35 m/s, which allows to make indistinctly long or short trails.
Our know-how in this technology reaches the 50 Tm/hour and pipes till DN200 mm
With a very low costs of investments and maintenance, it is a very flexible system in number of lines, with a continuous operation or in batch.
It is a total closed system, where the product is insulated, allowing to introduce through a pump or a blower, dry air into the pipe in order to keep the features of the product or from the inert gas if there is ATEX requirements (explosive environment). In this type of transport, air is introduced by a pump or blower inside the pipe, creating a relation of more air than product, and before they arrive to their destiny, the two elements get separated by a filter or cyclone.
We will choose the filter according to the product we must transport, although generically we will use textile sleeve filters or cartridges for powdery products, from mesh and/or paper for granulated products.
- In case of sleeve filters, the auto-cleaning system will be through a pressurized air flow in countercurrent controlled by a local PLC.
- In case of mesh and/or paper filters, the cleaning is made through an effect called implosion consisting in a vacuum valve to generate an inwards shockwave which makes the filter to vibrate, provoking the deposits to precipitate.
- For flakes or fibers, the filter is defined according to the existing powder quantity in the product.
