Pre-magnetic separation ore pulp distributor and method

Abstract

The invention discloses a pre-magnetic separation ore pulp feeding distributor and a pre-magnetic separation ore pulp feeding method. The distributor comprises a box body, an energy dissipation plateand an overflow plate. The energy dissipation plate and the overflow plate are longitudinally arranged in the box body and divide the interior of the box body into a slurry making area, an overflow area and an ore separation area in sequence, a slurry making water inlet and an ore inlet are formed in the upper portion of the slurry making area, and an ore discharging opening is formed in the lowerportion of the ore separation area. The box body comprises a bottom flow plate which is obliquely arranged. A gap is reserved between the bottom of the energy dissipation plate and the bottom flow plate to form a first channel. A gap is reserved between the bottom of the overflow plate and the bottom flow plate to form a second channel. An anti-blocking device facing the ore separation area is arranged on the bottom flow plate and used for dredging the second channel. According to the invention, ore feeding of the preselector is uniform, ore pulp sedimentation is avoided, functions of pulp making, overflow, ore separation, blockage prevention and the like are tightly combined, the structure is compact, the operation is convenient, the operation is stable and reliable, the maintenance amount is small, the operation rate is high, and smooth production can be efficiently guaranteed.

Description

technical field [0001] The invention relates to the technical field of pulp feeding equipment, in particular to a novel pre-magnetic separation feeding pulp distributor and method. Background technique [0002] At present, the magnetite beneficiation process is improving day by day, and the emergence of new process equipment such as high-pressure roller mills makes the application of pre-selection process before grinding more and more, and the large-scale pre-selection magnetic separator with particle size of 0mm ~ 12mm is also more mature. However, as the capacity of the concentrator is increasing, the number of pre-selectors is also increasing. During production, the pre-selection magnetic separator is fed with dry material belts, and the pre-selection magnetic separator needs a large amount of water to make slurry, and the large-size slurry in production cannot be uniform. At the same time, the phenomenon of ore slurry settlement often occurs. How to make the pre-separat...
