Dilute phase pneumatic conveying air velocity is higher, the material suspended in the vertical pipe was evenly distributed in the horizontal material was flying state, the porosity is very large. The material is transported mainly by the energy held by the higher velocity airflow.

Delivery Features:

1) The piping can be flexibly arranged so that the process equipment of the plant equipment is reasonable;

2) to achieve bulk transport, high efficiency, reduce packaging and handling costs;

3) system closed, dust flying less escape, environmental sanitation is good;

4) less moving parts, easy maintenance, easy to automate;

5) to avoid the material moisture, fouling or mixed with other debris, can guarantee the quality of conveying materials;

6) in the transport process can achieve a variety of process operations, such as mixing, crushing, grading, drying, cooling, measurement, dust and so on;

7) can be carried out by the number of points sent to one or by a decentralized to the number of long-distance operation;

8) For materials with unstable chemical properties, inert gas delivery can be used.

Dilute transport is the use of less than 1kg / c㎡ gas pressure, the use of positive pressure (pressure) or negative pressure (suction) or positive and negative pressure combination and a very high speed to promote or pull the material to make it Through the entire transmission line, so the delivery method is called low-pressure high-speed system, it has a high gas-material ratio.

At the beginning of the system about 10m / s2 acceleration, at the end of up to 1300m / min high speed, so the air flow rate is high. The initial pressure of the pipeline is generally less than 1kg / c㎡, while the end is basically close to the atmospheric pressure. Dilution of the power of the general use of air or nitrogen, power is generally provided by the centrifugal fan or Roots vacuum pump. When the dilute phase material in the pipeline was suspended state, the transmission distance of up to several hundred meters.

Dilution of negative pressure is characterized by a little or more from the bulk point to the height of the material delivery.

Dilution of positive pressure is characterized by a little from the low point to the multi-point material delivery.

Positive pressure and negative pressure can also be combined to meet the special requirements, more suitable for multi-point feeding multi-point material delivery to meet the complex requirements of the production process.
