Abstract
To limit the amount of solid particulate matter fed into an airlift pipeline from, especially, a suction nozzle device, the density of the suspension passing from the suction nozzle to the airlift system is measured. If the measured density is above a predetermined value, a proportion of the suspended solid material is removed prior to passing into the airlift pipe. The density of the moving suspension is determined by a radiation-type densitometer located upstream from the airlift pipe. The density can also be directly measured by a balance beam or weighing arrangement connected to a pivotable length of pipe. Where fine particles are present that are not to be considered in the densitometer measurement, a differential measurement can be obtained by a second measurement of the density of liquid from which the large particles have been screened.
