DEVICE FOR GRAVITY CONCENTRATION OF MINERAL RESOURCES Russian patent published in 2018 - IPC B03B5/62 

FIELD: mining.

SUBSTANCE: device for gravity concentration of mineral resources includes a hopper coupled to a distribution chamber, on both sides of which inclined ascending and descending separating transport channels are installed, in which overlapping plates are arranged with possibility of changing its spatial position, and an inclined discharge channel with a device for transportation of dispersed mineral material. The device is provided with pressure vessel for separating medium, connected by a pipe to the lower channel of the device through the inclined channel for unloading heavy product of coarse fraction, connecting device with dewatering elevator, and adjusting density of material separation by its specific weight by setting water level in pressure tank by means of movable gate device and maintaining the specified density of separation by lifting or lowering the gate device determining the level of water in the pressure tank. A pressure sensor is mounted on the upper part of lower channel and connected with the drive of the gate device, which keeps constant pressure automatic mode and specified density of separation in the lower channel of device. The descending transport channel is connected to the inclined discharge channel. A calibrating hole is installed in the lower part of the descending transport channel.

EFFECT: enhanced efficiency of material separation by density.
