DISK-TYPE CERAMIC FILTER SECTOR Russian patent published in 2003 - IPC

FIELD: filtering devices; filtration of pulp concentration products at concentrating mills. SUBSTANCE: sector of disk-type ceramic filter has framework with filtering and inner surfaces formed by sphere-shaped particles of synthetic corundum at ratio of sizes of particles in filtering surfaces to sizes of particles in inner surface ranging from 0.02 to 0.05. Located inside sector in parallel rows in two mutually perpendicular directions are inner elements; each inner element consists of two truncated cones made integral with framework over base and interconnected over surface of their section. Proposed sector increases permeability of filtering surface. EFFECT: increased productivity. 3 dwg, 1 tbl
