Description

Pulp separation barrel

Technical Field

The invention relates to the technical field of mineral separation, in particular to a slurry separation barrel.

Background

In the flotation process of minerals, a two-stage flotation method is mostly adopted at present, rough concentrates obtained in a pre-selection stage enter a thickener for concentration and then automatically flow and discharge into a heating barrel, and a 'Peterov method' is adopted during concentration, and final concentrates are obtained after a flotation process of one-step rough flotation, two-step fine flotation and three-step fine flotation.

In the prior patent, an external pulp separator for a flotation column (publication number: CN 211887430U) plays a role in dispersing and discharging pulp, but the pulp has fluctuation due to impact after entering an inner cylinder, and the pulp is often unstable and even intermittently cut off, so that the pulp classification effect is not ideal, the uniformity is poor, and mineral deposition can be generated when the pulp concentration is high.
