DEVICE FOR DENSE MEDIUM SEPARATION OF MATERIAL Russian patent published in 2017 - IPC B03B5/30 

FIELD: technological processes.

SUBSTANCE: device comprises a bath tapering downwardly, having a loading device in the upper part and an overflow board on the opposite side of the bath for unloading the float product and an opening in the lower part connected to a discharge pipe for unloading the drowned product. The device is equipped with oscillating screens for float and drowned fractions, a drowned product level sensor and a control unit. The outlet of the discharge pipe is located above the mesh of the oscillating screen for the drowned product. The control unit is connected to the level sensor and to the oscillating screen for the drowned product with the possibility of adjusting the frequency of oscillations of the screen mesh, thereby regulating the discharge speed of the drowned product and maintaining the level of the drowned product at the bottom of the bath. The bath has the shape of a pyramid turned upside down, while the bath wall on the side of the loading device has an arc shape concave into the bath in its vertical section. The bath wall on the side of the tail board and the adjacent side walls are flat and located at an angle of 45-60° to the horizon. A valve is installed at the outlet of the discharge pipe. A magnetic lock connected to the control unit is installed on the discharge pipe with the possibility of regulating the flow velocity of the magnetite slurry and the drowned product. The discharge pipe is located with an inclination angle of the axis to the horizon from 90 to 45°. On the side of the tail board of the bath there are revolving arms.

EFFECT: increasing the efficiency of material separation, reducing the consumption of the suspension.
