Dilute phase transport is to use a pressure of less than 1kg / c2, using positive pressure (pressure feed) or negative pressure (suction) or positive and negative pressure combination and push or pull the animal material at a relatively high speed to pass The entire conveyor line, so this mode of transport is called a low-pressure high-speed system, which has a high gas-to-material ratio.

At the beginning of the system, there is about 10m/s2 of acceleration, and the end can reach a high speed of about 1300m/min, so the airflow speed is high. The pressure at the beginning of the transfer line is less than 1kg/c2, and the end is almost close to atmospheric pressure. The power of the dilute phase is generally air or nitrogen, and the power supply is generally provided by a centrifugal fan or a Roots vacuum pump. When the phase is dilute, the material is suspended in the pipeline and the transport distance can reach several hundred meters.

The characteristic of dilute phase negative pressure conveying is that material can be transported from a point or a plurality of points in the bulk to a high point.

The characteristic of dilute phase positive pressure conveying is that material can be transported from a low point to a multi-point.

Positive pressure and negative pressure can also be combined to meet special requirements, and it is more suitable for multi-point feeding multi-point discharge conveying method to meet complex production process requirements.
