Design guidelines for granular particles in a conical centrifugal filter
چکیده انگلیسی

Essential design criteria for successful drying of granular particles in a conical continuous centrifugal filter are developed in a dimensionless fashion. Four criteria are considered: minimum flow thickness (to ensure sliding bulk flow rather than particulate flow), desaturation position, output dryness and basket failure. The criteria are based on idealised physical models of the machine operation and are written explicitly as functions of the basket size lout, spin velocity Ω and input flow rate of powder Qp. The separation of sucrose crystals from liquid molasses is taken as a case study and the successful regime of potential operating points (lout, Ω) is plotted for a wide range of selected values of flow rate Qp. Analytical expressions are given for minimum and maximum values of the three independent parameters (lout, Ω, Qp) as a function of the slurry and basket properties. The viable operating regime for a conical centrifugal filter is thereby obtained as a function of the slurry and basket properties.


► Essential design criteria are given for conical centrifugal filters (CCFs).
► CCFs separate slurry into granular solid and liquid as a continuous process.
► The criteria are: flow thickness, desaturation, outlet dryness and cone failure.
► The criteria are based on idealized physical models of the machine operation.
► The viable operating regime is given as a function of the slurry and cone properties.
