Dense phase conveying is divided into transmission tank delivery and rotary valve delivery. The transmission of the tank is carried out by pressure to a certain pressure by using the transmission tank, and the material is conveyed by switching the feeding valve and the pneumatic to the material. This kind of conveying air velocity is low and the solid gas ratio is high, and the conveying pressure is higher. Conveying gas is often used in air or nitrogen, the power is generally provided by the compressor. The main characteristics of the transmission speed is low, the impact on the quality of the material is small. The rotary valve dense phase conveying is a dilute phase positive pressure conveying mode, and the power is supplied by the compressor. The system has high pressure, low flow rate, but has a great effect on the quality of materials.
