Product Description
This kind of conveying system works by pushing the material along the pipe in a plug form, with the help of compressed air blown into the pipeline by a pressure vessel.
Dense phase pneumatic conveying systems can be used to transport a large range of bulk materials, both in the form of powders or granules. They can reach distances longer than 500 metres and capacities over 100 t/h.
The low conveying speed used in dense phase pneumatic systems helps preventing the material degradation and preserves the product quality and integrity. It is suitable to handle any kind of product, including fragile, abrasive and lumpy materials and blends.
Dense phase transport has a high product/air efficiency ratio. The indicative ratio of air or gaseous fluid to the product is about 30L of gas per 1Kg of product. Thanks to the reduced amount of air needed, this system allows reduced energy consumption.
Pneumatic conveying systems offer the benefit of low maintenance costs: the number of spare parts and maintenance services needed to maintain the system running is limited.
Dense phase pneumatic transport sizing
The design phase of a pneumatic transport requires an analysis of the material and the transport requirements (such as flow rate and distance). Then, you need to work out the amount of air needed. Air-Tec can engineer pneumatic conveying systems customised on the initial analysis results.
Dense phase pneumatic systems are an efficient and cost-effective solution for conveying abrasive and friable material. Slow convey speed and low amount of air/gas used, means less wear and tear on the pipeline, product integrity and reduced maintenance costs.
Dense phase pneumatic conveying systems can be used together with any equipment, for example:
extractors
silos
screw conveyors
hoppers
big bag emptying stations
bag splitters and filters
Furthermore, they can be also used in ATEX settings thanks to the possibility to use nitrogen for the transport.
1. The working pressure is high, so it can realize long-distance and high-capacity transportation; the booster can realize ultra long-distance transportation;
2. Due to the low conveying speed of materials, the abrasion of conveying pipes and materials is less;
3. High material gas ratio, low gas consumption and low operation cost;
4. It can transport from single point to multi-point, and is easy to process design;
Basic parameters:
1. Conveying pressure: 0.2MPa ~ 0.5MPa (determined according to the specific gravity, distance and height of materials)
2. Required air source pressure: not less than 0.45MPa
3. Material gas ratio: 10kg ~ 85kg / kg
4. Conveying speed: initial 0.5m/s to end 12m / S
