Air lift pump is vertical pneumatic conveying equipment suitable for vertical conveying of short distance with general conveying capacity of 10-200t/h. Conveying height of 30-50m is more economical and high up to 80m. Air lift pump has the advantages of simple structure, no moving parts, no large easy worn parts, reliable operation, convenient maintenance and repair. Conveying unit power consumption is in low level which is around 0.6-1.0kwh/t. But when the lifting height is low, power consumption will be higher than that of elevator.
