Ultrafine coal classification using 150 mm gMax cyclone circuits
The simulated process shows that the 25 μm quartz particles, close to the cut size, need much more time than the finer and coarser particles to reach the steady flow rate on the outlets of hydrocyclone. For the particles in the inner swirl, with the quartz size increasing from 5 to 25 μm, the particles take more time to enter the vortex finder.
