FIELD: mineral processing equipment.
SUBSTANCE: invention can be used to separate solid particles by density, for example, it can be used to process gold ores and fine sands, as well as copper-nickel ores that are not amenable to magnetic separation. The concentration cup consists of an upper section connected to each other, a lined section and a bottom. The upper section of the bowl includes an inner frame covered with the material of the working surface of the upper section with the formation of protrusions and cavities between the protrusions. The lined section includes an inner frame provided with a wear-resistant material lining to form the working surface of the lined section. Wear-resistant material lining is made with the possibility of independent replacement and includes at least two lining elements. At least one lining element is provided with a plate.
EFFECT: increase in the service life of the concentration bowl, its maintainability, reliability of the device and ease of manufacture.
