BOILED DILUTED PULP CLASSIFICATION SYSTEM Russian patent published in 2018 - IPC B03B7/00 C01F7/06 

FIELD: metallurgy.

SUBSTANCE: invention relates to the hydrometallurgical production equipment and is intended to perform the classification process by to the various suspensions solid phase dispersed composition and can also be used in other areas of industry, where contained in the suspension solid phase classification is required. Boiled diluted pulp classification system contains cylindroconical hydroclassifier with the boiled diluted pulp supply, hydroclassifier overhead product desiliconization tank and the bottom product removal from the hydroclassifier cone to the upper arc screen with washing water supply for the top size product mixing. Upper arc screen top size product output is in communication with the mixing device with the red mud output into the thickener, and the top size output is in communication with the lower arc screen with the fine red sludge pulp supply for the lower arc screen top size mixing. Lower arc screen bottom product output is in communication with the mixing device with the red mud output into the washer, and the lower arc screen top size output is in communication with the mixing device with output for the sludge removal. For the products removal from the hydroclassification cone and mixing devices, pumps are used, for example, centrifugal pumps.

EFFECT: technical result is reducing the load on the mixing devices drives, thickeners and washers, possibility of the high-iron bauxite processing.
