Description
Affiliated technical field
The invention belongs to Wet-type centrifugal class compound force field preparation equipment, more particularly, it relates to a kind of centrifugal ore separator that carries out sorting by the alternating force-field type effect.
Background technology
The wet type gravity separation method is meant through the ore pulverized in the ore pulp system that with water is medium, rely on different densities the suffered gravity of particle difference and have different sinking speed, thereby realize the beneficiation method that the weight mineral separate.Traditional gravity separation method is because the main effect that relies on gravitational field, thereby it is lower to sort efficient, and treating capacity is little, restricted application.Particularly, for example less than 19 microns particle, only depend on gravity can't make its effective sedimentation, thereby also can't make its effective sorting for subparticle.Therefore, since the sixties in last century, people have introduced centrifugal force in the gravity separation process, have formed the compound force field beneficiation method.After having added powerful centrifugal force, just quickened the sedimentation of micro-size fraction mineral, make the micro-size fraction mineral also can carry out sorting effectively by density variation.The capital equipment that is used for such compound force field ore dressing is a centrifugal ore separator.The centrifugal ore separator that has used on producing all is to utilize the conical butt rotary drum of rotation at a high speed to carry out ore dressing at present.
All drum-type centrifugal ore separators, mine tailing can successfully be discharged automatically, does not have problems substantially.Concentrate can't be discharged automatically owing to powerful action of centrifugal force is close on the drum inner wall only.Thereby the automatically continuous ore discharge problem of solution concentrate, always be the key of successfully developing the drum-type centrifugal ore separator.
According to drum rotating axis and horizontal relation of plane, centrifugal ore separator can be divided into horizontal and vertical two types: be called horizontal centrifugal ore separator if the axis of rotary drum is parallel with horizontal plane; Be called the vertical centrifugal ore separators if the axis of rotary drum is vertical with horizontal plane.The representative of horizontal centrifugal ore separator, domestic have cloud tin formula centrifugal ore separator, SL type jet and centrifugal ore separators and an adverse current platoon centrifugal ore separator etc.The external many times of gravity concentrators (MGS) that Britain is then arranged etc.; The vertical centrifugal ore separators is mainly by external development, and its representative has Nelson's (Knelson) centrifugal ore separator and Kelsey (Kelsey) centrifugal ore separator etc.Although the invention of all kinds of centrifugal ore separators and use for traditional gravity beneficiation equipment, can both more effectively be reclaimed the mineral grain of micro-size fraction, its shortcoming is arranged respectively also.Cloud tin formula centrifugal ore separator can not turn round continuously, can only be interrupted to ore deposit and ore discharge, and energy consumption and water consumption are all high, stop using substantially now.Jet and centrifugal ore separators and adverse current platoon centrifugal ore separator all are to utilize plus high-pressure water spray on the basis of cloud tin formula centrifugal ore separator, and the concentrate that will be deposited on drum inner wall by the impulse force of water is gone out rotary drum and realized continuous ore discharge.Though they have solved the continuous ore discharge problem of concentrate, and have the sorting index advantage of higher, but still, fail so far extensively to promote the use of owing to water consumption, energy consumption height, must add shortcomings such as water purification installation and mechanical stability be relatively poor.Many times of gravity concentrators (MGS) are although sorting result is better, and its concentrate ore discharge mode is to adopt mechanical type scraper plate ore discharge, and it is bigger to make that device structure complexity, scraper plate wear and tear, and costs an arm and a leg.End is got up, and the major defect of existing horizontal centrifugal beneficiating equipment is or can only be interrupted to ore deposit and ore discharge, can not move continuously; Though can move continuously, the continuous ore discharge problem of concentrate is also come fine solution.Therefore, develop and a kind ofly can give ore discharge continuously, simple in structure and novel centrifugal ore separators that the water power energy consumption is low is the target that dresser author pursued always.
Up to the present, with flexible belt replace centrifugal ore separator rigidity rotary drum, ore discharge is not discharged by high-pressure washing water and scraper plate, concentrate and mainly not yet there are no report by rotary drum revolution centrifugal force and the little centrifugal ore separator of water consumption continuously.
