Technical Field

The invention relates to the technical field of ore pulp screening, in particular to an ore pulp dewatering and screening device.

Background

The screening part of the existing sieve bend is a stainless steel strip slotted screen, and the whole sieve bend consists of 1 or 2 screen meshes. The ore pulp enters the sieve bend from the feeding end, passes through the sieve bend surface through the feeding initial speed and the gravity action height, and is dewatered through the sieve holes. The existing stainless steel slotted screen is inconvenient to replace, uneven in abrasion and quick in abrasion. Because the ore pulp is difficult to feed evenly when entering the screen, the wear of the screen is uneven, the feeding end of the screen is a main dewatering area, the wear is smaller when the feeding end is closer to the discharging end, but the whole screen needs to be replaced when one part of the screen is worn because the whole screen is formed.
