The Effect of Dry Granulating Machine Spindle Eccentricity on the Granulation

Abstract:

For the dispersity of particles in the process of ceramics dry granulating, simulating the effect of spindle eccentricity on it based on the Euler-Euler model. Simulation results show that the volume fraction of particles in the granulating chamber were 52%, 53%, 51% when the spindle eccentricity were 15mm, 25mm, 35mm. For particles distribute in the region of packing density above 0.4kg/m3 , the volume fraction in the granulating chamber were 11%, 3%, 7%. Therefore, spindle eccentricity has little effect on the whole the volume fraction of particles, but the effect on particles distribute in the region of packing density above 0.4kg/m3 is larger .Particles dispersity is best in the process of granulating when spindle eccentricity is 30mm.
