PERIODICAL WORKING CENTRES FOR THE DISCENTRATION OF FULL MASS

摘要

A centrifuge for separating massecuite into solid and liquid fractions has a rotatable drum which includes a circumferential wall having a small and uniform thickness, and top and bottom walls. Sieves for separating massecuite into its constituent liquid and solid fractions are located in an inner chamber which is bounded by the walls of the drum. At least two rows of holes are formed in the circumferential walls through which the liquid fraction is discharged whereas the solid fraction retains in the inner chamber. The drum is reinforced in the regions of the top and bottom walls, for instance by means of two ring members which are fitted on the circumferential wall adjacent to the top and bottom walls. On the other hand, it can be reinforced by means of inclination of the top wall and/or the bottom wall to a horizontal plane. It is also possible to provide the reinforcing ring member adjacent to the bottom wall and to incline the top wall of the drum, and vice versa.
