FIELD: performing operations.
SUBSTANCE: invention relates to a method of making a concentrator bowl of a centrifugal concentrator. Result is achieved by the method of making a concentrator bowl of a centrifugal concentrator, which includes a frame, protrusions and cavities between the protrusions. According to the method, the bowl element is attached to the inner surface of the bowl workpiece so that at least one mould is attached, the profile of which follows the profile of the bowl element, polymer composition is supplied to the inner surface of the bowl workpiece into the above mould, the bowl element is moulded from the polymer composition and the mould is removed. wherein ledge is attached to the bowl workpiece inner surface while the bowl workpiece including carcass is preliminary made from polymer composition.
EFFECT: increased resistance to abrasive and impact wear of the centrifugal concentrator concentration bowl and improvement of its repairability.
