MODULAR CONCENTRATION BOWL OF A CENTRIFUGAL CONCENTRATOR AND THE METHOD FOR ITS MANUFACTURE (OPTIONS) Russian patent published in 2022 - IPC B04B3/00 B04B7/08 B03B5/28 B03B5/32 

FIELD: mineral processing.

SUBSTANCE: invention relates to devices designed for the mineral processing, and can be used to separate solid particles by density. The invention can be used for processing gold-bearing ores and fine sands, as well as copper-nickel ores that are not amenable to magnetic separation. The modular concentration bowl of a centrifugal concentrator consists of interconnected upper and lower parts, as well as a working surface attached to them. At the same time, the upper part of the bowl has an internal frame. The working surface of the modular concentration bowl covers the inner surface of the upper part of the concentration bowl with the formation of protrusions and cavities between the protrusions. At the same time, at least one insert is attached to the inner frame of the upper part of the bowl to form at least one protrusion. The invention contains a method for manufacturing a modular concentration bowl of a centrifugal concentrator (options).

EFFECT: increase in the service life of the concentration bowl, its maintainability, reliability of the device and ease of its manufacture.
