    Abstract: 669,194. Centrifugal machines. MAATSCHAPPIJ VOOR KOLENBEWERKING STAMICARBON N. V. March 24, 1949 [March 25, 1948], No. 8111/49. Class 23 A liquid, with solids in suspension, is fed to a cyclone 1 provided with a diffuser 7 which is adjustable to vary the outflow from the cyclone core. The apex 9 is immersed in liquid in a container 4 and, according to the position of the diffuser, liquid is discharged from the cyclone to the container or vice-versa. Solids may be separated out in the cyclone, fall into the container 4 and be removed therefrom as by a screw apparatus 5 or by other means, and liquid may be supplied to the container in counterflow to the solids being removed by the screw. The apparatus may be used to form a concentration of liquid containing solid particles, the concentration being removed from the container 4. The latter may be constructed as a classifier by fitting to its bottom a downcomer, for the solid particles, in which an up-current of liquid flows. The diffuser cover plate 14 may have a flat bottom. The apparatus may be used for the separation of shale from raw coal or separation of gangue from ores.
