Abstract
A source of fluid and entrained particles including fines is connected to the entrance of a cyclone particle separator lying above a particle storage vessel that has an outlet near its bottom. The particle separator has a particle exit connected to the storage vessel and a fluid exit. The separator imparts angular motion to the fluid received at its entrance such that the fluid with a first percentage of the fines entrained therein flows out the fluid exit, and the particles minus such first percentage passes through the particle exit to the storage vessel. The particles in the storage vessel are fluidized to a particular level above the outlet. Fluidized particles with a second percentage of the fines entrained therein are removed from the process by withdrawal from the storage vessel at a point between the particular level and the outlet. Fluidized particles minus the first and second percentages of the fines flow from the outlet of the storage vessel to a receiver for processing. The average size of the fluidized particles leaving the outlet is controlled by changing one of the percentages of the fines. When the quantity of fines included in the fluid entrained particles from the source becomes too great, the angular operation of the separator is disrupted by injecting fluid into its base, or by raising the level of fluidized particles in the storage vessel to increase the percentage of the fines flowing out the fluid exit of the separator. When the quantity of fines included in the fluid entrained particles from the source decreases, a portion of the fines withdrawn from the storage vessel is returned to the storage vessel to decrease the second percentage.
