Technical field
The present invention is a kind of preparation equipment, shaking table formula crossing current belt ore separators.
Background technology
Shaking table and belt ore separators (claiming belt chute again), though direction and shaking table that the belt ore separators ore pulp that particularly flows over flows are roughly the same, the mode of the power that ore particle is suffered and direction have very big difference.Shaking table has been to use the gravity beneficiation equipment of last a century, and technology has been driven maturation, but the shortcoming of shaking table is: disposal ability is little when sorting the fine fraction mineral aggregate, and the rate of recovery is low, and treating capacity can be overflow bed again when increasing, and mineral aggregate is heaped, and separation index descends; Be consumption of wood big and the bed surface easy scale formation or the deformed damaged of shaking table in addition, need periodic maintenance, use cost is high.Particularly a large amount of raw lacquer of shaking table bed surface needs are coated with and rinse, and the raw lacquer allergic reaction often appears in the operator, has a strong impact on the healthy of workman.Simultaneously surrounding environment also there is bigger pollution, is unfavorable for environmental protection.Existing crossing current belt ore separators is high to ore deposit one end, ore discharge one end is low, and concentrate is discharged from the direction of belt movement.Give the direction of motion of ore deposit, mine tailing vertical with the direction of motion of concentrate.
The advantage of crossing current belt ore separators is that concentration ratio is high, is convenient to the multiple stratification setting, and is free from environmental pollution.Shortcoming is 1/3rd places that the vibration revolving gear is located at equipment, and active force is confined to the part, and the loose power of mineral is not enough, and treating capacity is very little; Belt does not have anti-deviation device, causes belt deviation to damage easily.Revolving gear especially for loose mineral has an eccentric hammer, and high speed spin safe hidden danger is big.
Moreover crossing current belt ore separators has only the motion of belt around two wheels, and is relatively more dull, should this motion be far from suitable for the bigger mineral aggregate material crowd of granularity, just much little than shaking table.If can find a kind of suitable method that the setting and the existing crossing current belt ore separators of the shaking of shaking table, reflex bar are organically combined, just might put forward the sorting capability of long equipment significantly, improve the recycling level of big proportion nonferrous metal ore.Such equipment is not reported so far.
