According to the principle of the dressing equipment and function different, gravity separation can be divided into the following categories. Symons cone crusher
(1) ore washing by mechanical force, water conservancy scour scrub, by clay bond/cemented the ore, broken, dissociation of fine clay and break in the process. It is gravity separation shop help role. In the crude ore containing mud (0.074 mm)-higher (more than 10%), often need to wash the ore.
(2) hydraulic classification according to different particle size and density of ore particles in medium (general) for water in the different rates of precipitation, ore particle group is divided into two or more than two particle levels of the process. It is also gravity separation shop help ball mill homework.
(3) jig dressing using vertical pulse medium flow make mine, and particle swarm loose density stratified according to, so that the different density mineral separated from the process.
(4) chute dressing use of water to flow along the inclined plane for mineral separation process.
(5) wave bed in a sloping dressing is wide on the bed, bed with asymmetric reciprocating motion and thin layer cant role mineral water supply in the process. General to ore size 3 ~ 0.037 mm.
(6) heavy medium dressing use as well as the principle that the different density of mineral in heavy liquid or heavy suspension of separated from each other. Sometimes in choose don't work with this method to remove a lot before (40% ~ 50%) of the gangue to increase production capacity. General feeding size in the 75 mm below.
The above all kinds of mineral processing, are a different density for the main basis. But it must be pointed out that in other conditions being at the same time, along with granular degrees, according to reduce crazy the density of separation difficulty will be increased. Therefore, in order to enable the mineral grains by as much as possible, and the material in the chosen separation density should be fine particle removal don't before, or grade level into a narrow size range of level.
Fine grain by particles of the material level quality, and so are less in the gravity field according to the density of granularity separation or speed and accuracy reduced greatly, fine particle metal loss caused by level. To improve the microgranular level technology can be used, the recovery in centrifugal field for principle of gravity separation equipment and various kinds of force of the combined action of gravity separation equipment, such as processing machine, centrifugal heavy medium hydrocyclones, washing machine and spiral ore spiral chute, rotating spiral chute, etc .Impact stone crusher
