Method and apparatus for pneumatically evacuating centrifuges

摘要

A method and an apparatus for pneumatically evacuating a vertical centrifuge (12), the drying gas moving as a secondary flow (54) being converted-prior to its combination with the mixture of product and gas conveyed through the discharge pipe-into a turbulent longitudinal flow essentially enclosing the discharge pipe as far as its downstream end, in order to prevent caking of the centrifuged material within the discharge pipe or in conveying lines (20) attached thereto and also to shorten the length of the drying pipe.
