Abstract

The invention discloses a hydraulic power sorting unit which comprises a container, a sand setting hole arranged at the bottom of the container, a central feeding tube arranged at a central shaft of the container, an ore pulp inlet opened at the upper part of the central feeding tube, and a turbulent current device installed in the central feeding tube; the interior of the container is divided into a static state settlement zone, a transition settlement zone and a turbulent fluctuation settlement zone; the transition settlement zone of the container is internally provided with a steady flow plate component which is formed by combining a plurality of 'Z'-shaped plates which are mutually fixed by grooves arranged on the 'Z'-shaped plates after rotating at 180 degrees. The hydraulic power sorting unit can improve the settlement separative efficiency between a diasporite and granule silicate minerals in the process of aluminum ore processing.

Description

technical field [0001] The present invention relates to a sorting device, in particular to a hydraulic sorting device, which belongs to the technical field of mineral sorting. Background technique [0002] In the processing and production of aluminum ore, we found that there is a certain difference in the grindability of aluminum minerals and silicate minerals in bauxite ore. Through selective grinding, most silicate minerals are easy to grind, while some monohydrate The particle size of durasite is relatively coarse, and the density of aluminum minerals is slightly larger than that of silicate minerals. Therefore, the method of hydraulic sedimentation separation can remove silicate minerals to a certain extent and improve the aluminum-silicon content of bauxite. Compare. [0003] At present, in the industrial production of aluminum ore beneficiation, commonly used hydraulic separation equipment includes hydrocyclones, thickening hoppers, high-efficiency inclined plate thic...
