Under certain conditions, airflow is used as a carrier medium to transport powder and granular solid materials in a pipeline. The pneumatic conveying system is mainly composed of sending equipment, conveying pipeline, material and gas separation equipment, gas source and purification equipment, etc.

Dilute Phase Pneumatic Conveying:

① Adopt positive pressure (pressure feed type)
② Negative pressure (suction type)
③ Positive and negative pressure combination
④ Dense phase pneumatic conveying

Dense Phase Pneumatic Conveying:

① Dense phase conveying is also called sending tank or warehouse pump conveying
② There are two ways of sending tank transportation: sending tank (storage pump) positive pressure honey phase transportation, sending tank combined full load transportation
