MODULAR CONCENTRATION BOWL OF CENTRIFUGAL CONCENTRATOR AND VARIANTS OF METHOD FOR ITS MANUFACTURING Russian patent published in 2021 - IPC B04B3/00 B04B7/08 B03B5/28 

FIELD: minerals beneficiation.

SUBSTANCE: invention relates to a device designed for the beneficiation of minerals, and can be used to separate solid particles by density, in particular for the processing of gold-bearing ores and fine sands, as well as copper-nickel ores that are not amenable to magnetic separation. The modular concentrating bowl consists of an interconnected upper and lower part, as well as an elastic work surface attached to them. The upper part of the bowl includes a frame with annular ribs. The working surface covers the inner surface of the upper part of the concentration bowl with the formation of annular protrusions in the region of annular ribs and cavities between annular protrusions. On at least one annular rib of the upper part of the bowl, at least one insert made of wear-resistant material is fixed, which is additionally fixed by the material of the working surface. Also proposed is a centrifugal concentrator containing the proposed modular concentration bowl and options for the method for its manufacture.

EFFECT: increasing the service life of the centrifugal concentrator, the reliability of the device and the simplicity of the method for its manufacture.
