Ore dressing processing and application and classification of Chute:


Chute processing was conducted by using the method of slope flow sorting process. Ore grain mixture to the small Angle of oblique groove, general is 3 ° ~ 4 °, no more than 6 °. Momentum, mineral grains in water flow under the action of gravity and centrifugal force and friction force to make particles by density stratification. Because the flow velocity distribution in the slot is upper lower small, so the density of larger particles concentration in the lower, smaller water momentum and larger tank bottom friction, move forward slowly along the groove bottom, density of small particles is concentrated in the upper, carried by water from escaping from the tank at a rapid speed. Then, according to the layer, respectively, the closure can be density is different two products concentrates and tailings.


Chute is a lot of more phyletic, according to the ore grain of reaction can be divided into the chute of gravity, centrifugal force chute; According to the selected granularity can be divided into coarse chute, ore chute and slime chute. Coarse grain chute due to need a lot of artificial operation, often replaced by jig. Common chute are shown in table.
