Definitions
- the claimed invention relates to devices designed for mineral processing, and can be used to separate solid particles by density.
- the claimed 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 known device contains a cone-shaped concentration bowl.
- the inner frame of the concentration bowl is made of a monolith and consists of a base and a side wall.
- the side wall of the frame contains a number of metal frame ribs.
- the working surface of the concentration bowl is formed by the inner surface of the concentration bowl and contains a number of protrusions formed by the frame ribs and cavities located between them.
- the known device has a number of disadvantages, namely, the fact that the inner frame of the concentration bowl is made monolithic, which excludes the possibility of replacing the upper and lower parts of the concentration bowl independently of each other, and also excludes the possibility of vertical division of the concentration bowl into interchangeable segments.
- the working surface of the inner frame of the concentration bowl there are no wear-resistant elements, such as inserts made of wear-resistant material, which significantly reduces the service life of the concentration bowl.
- the working surface of the concentration bowl is made of non-elastic material, which significantly reduces the service life of the concentration bowl of the known device.
- a well-known concentration bowl consists of vertical segments hollow inside, each of which consists of two vertical pieces. In the design of the segments, protrusions and cavities located between the protrusions are made on the inner side. In the cavities there are nozzles for injection of the fluidizing liquid. On the surface of at least one protrusion, at least one insert made of wear-resistant material is fixed. As one possible implementation of the known concentration bowl, inserts of wear-resistant material can be located inside the protrusions of the vertical segments of the concentration bowl.
- the known invention has a number of significant disadvantages, namely, the lack of a known concentration bowl of a rigid inner frame with a side wall containing metal ribs.
- inserts made of wear-resistant material are fixed on the surface of the protrusions of the segment, that is, on the working surface of an elastic material, which increases the risk of separation of the insert from the working surface during operation of the claimed invention due to abrasive wear of the working surface. If the inserts of wear-resistant material are located inside the projections of the segment, the disadvantage is that the base of the insert is not attached to a rigid inner frame, for example, to a metal rib of the inner frame.
- this type of construction does not provide reliable fastening of inserts made of wear-resistant material, and therefore does not provide an increase in the service life of the known invention.
- there is no external frame of the concentration bowl which significantly reduces its reliability and reduces the duration of its service life.
- the metal ribs of the inner frame are attached to the modular side wall of the inner frame of the concentration cup with fasteners forming the inner support structure.
- the metal ribs of the inner frame of the concentration bowl in turn, covered with an elastic material forming a replaceable working surface.
- inserts of wear-resistant material are attached from the outside.

- Known device works as follows.
- the mixture is fed into the cone-shaped concentration cup using a raw material feeder. After that, the concentration bowl is rotated. Then, the fluidizing liquid is supplied through the nozzles, and the components of the mixture, which have a higher density, are collected in the cavities of the working surface, after which they are removed using the concentrate discharge device. Also, with the help of a tailings removal device, light fractions obtained as a result of the gravity separation process are removed.
- the known technical solution has a number of significant drawbacks, which consist in the fact that inserts made of wear-resistant material are placed on top of the working surface of the concentration cup and fixed to it with glue. This significantly reduces the service life of the concentration bowl, since there is no reliable fastening of inserts made of wear-resistant material. Accordingly, during operation, the working surface is destroyed in the area of contact with inserts made of wear-resistant material and their subsequent separation from the working surface of the concentration bowl.
- inserts of wear-resistant material are fixed between frame ribs in cavities, then inserts of wear-resistant material are designed to prevent abrasive wear of annular cavities during operation of a known device, and not annular protrusions on the working surface. In turn, this feature does not allow extending the service life of the known concentration bowl, since it is the annular protrusions of the working surface that are subject to maximum wear during operation.
- the concentration cup is made as follows. First, the inner frame of the cone-shaped concentration cup is assembled by attaching to the base of the side wall of the inner frame made of nickel. The side wall is also provided with nozzles for injecting the waiting liquid.
- the side wall is covered with a layer of TiN with a thickness of 0.1 ⁇ m to 10 ⁇ m, thereby creating a coating of wear-resistant material, after which the protrusions are fixed on the inner surface of the side wall of the inner frame.
- the known method for manufacturing a concentration bowl of a centrifugal concentrator has a significant drawback, which is that the described method does not allow creating a concentration bowl, the working surface and protrusions of which were protected by wear-resistant material, ensuring a long service life of the resulting concentration bowl.
- a well-known invention discloses a method for manufacturing a concentration bowl of a centrifugal concentrator. First, internally hollow vertical segments are made, consisting of two vertical parts. Protrusions and cavities located between the protrusions are made from the inner side of the vertical segments. After that, nozzles are made in the cavities for injection of the fluidizing liquid. Next, on the surface of at least one protrusion, at least one insert made of wear-resistant material is fixed. As one of the possible implementations of the method of manufacturing a known concentration bowl, inserts of wear-resistant material can be placed inside the protrusions of the vertical segments of the concentration bowl. After that, the vertical segments are interconnected to form a concentration bowl.
- the known method of manufacturing a concentration bowl has a number of significant drawbacks, namely, the absence of a concentration bowl obtained according to this method of manufacture, a rigid inner frame with a side wall containing metal ribs.
- inserts made of wear-resistant material are fixed on the surface of the protrusions of the segment, that is, on the working surface of an elastic material, which increases the risk of separation of the insert from the working surface during operation of the resulting concentration bowl due to abrasive wear of the working surface. If the inserts from wear-resistant material is placed inside the protrusions of the segment, the disadvantage is the lack of attachment of the insert base to the rigid inner frame, namely, to the metal rib of the inner frame.
- this type of construction of the concentration cup obtained according to the known manufacturing method does not securely fasten the inserts of wear-resistant material, and therefore does not provide a concentration cup having a long service life.
- this type of construction of the concentration bowl, obtained according to the known method of manufacture does not provide reliable fixation of the segments of the concentration bowl relative to each other due to the lack of an external frame of the concentration bowl, which also significantly affects the maintainability of the device obtained according to the known method.
- fasteners are first mounted on the side wall at the locations of the metal ribs of the inner frame, and then, the metal ribs of the inner frame are placed on the fasteners. After that, an elastic material is applied to the surface of the metal ribs of the inner frame, with the formation of a working surface. Then the cavities located between the metal ribs of the inner frame are provided with nozzles for injection of the fluidizing liquid. After that, to the protrusions on the working surface, formed by the metal ribs of the inner frame, with the help of glue, inserts of wear-resistant material are attached over the working surface.
- inserts of wear-resistant material in the implementation of the known invention can be fixed in the cavities between the ribs of the inner frame.
- the inserts of wear-resistant material are fixed in the cavities between the ribs of the inner frame, then the inserts of wear-resistant material are designed to prevent abrasive wear of the cavities during operation of the known device, not protrusions on the work surface. In turn, this feature does not allow extending the service life of the known concentration bowl, since it is the protrusions of the working surface that are subject to maximum wear during operation.
- the known method of manufacturing a concentration bowl of a centrifugal concentrator has a significant drawback due to the fact that the installation of inserts made of wear-resistant material is carried out on top of the working surface. Thus, during operation, the elastic material of the working surface under the inserts wears out and the inserts detach from it.
- only the upper part of the concentration cup obtained according to the known method will be independently replaceable, while the lower part remains rigidly fixed.
- this type of construction of the concentration bowl, obtained according to the known manufacturing method does not provide the possibility of vertical separation of the upper part of the concentration bowl into interchangeable segments, fixed, including, by the outer frame of the upper part of the concentration bowl, due to its absence, which significantly affects the maintainability known device.
