Abstract

Three semi-empirical equations are derived to characterize the performance of the nozzle discharge centrifuge as a thickener for flocculated kaolinite slurries. The first equation relates mass throughput to machine size and speed, the number and size of nozzles and the product concentration. The second equation relates the maximum clear effluent rate to the settling characteristics of the slurry and to machine parameters. The third equation relates power consumption to product and effluent rates and to machine parameters. Finally a numerical example of the use of the equations is given.
