Description
Technical field
The present invention relates to a kind of preparation equipment, especially a kind of have ore dressing function and a big continuous wind-force centrifugal ore separator of disposal ability.
Background technology
The various mineral reserve of occurring in nature have gangue and impurity owing to mixing, thereby, after ore is dug out, all to sort.In the prior art, preparation equipment mainly contains jigging machine, shaking table, spiral concentrator, magnetic ore separators and centrifugal ore separator etc.
Jigging machine is to utilize diaphragm of rubber to pump, cause agitating of water with the ore gravity segregation, utilize current that the gangue and the impurity on its upper strata are washed away again, reach and separate the purpose that sorts, this kind equipment is mainly used in and sorts the less thin ore deposit of particle, and its water consumption is very big, and disposal ability is little.The ore dressing principle of shaking table is to make inertia that reciprocal assymmetric motion produces and frictional force and laterally under the effect of flushing water at the inclination bed surface with reflex bar, mine particle group on it is pressed proportion and granularity layering, and travel longitudinally and do transverse movement along the inclination bed surface along bed surface, discharge by concentrate end and mine tailing side gradually, the same jigging machine of this kind equipment, also be mainly used in and sort the less thin ore deposit of particle, and its water consumption is also very big, disposal ability is too little.Spiral concentrator is to utilize the slope variation of spiral chute cross-section curve to sort ore particle, has advantages such as movement parts simple in structure, no, in light weight, noiselessness, configuration be easy to installation and maintenance, but is mainly used in sorting of fine particles material.The magnetic ore separators is mainly used in that sort can be by the ore of magnetic attraction.Centrifugal ore separator is to produce differential settlement when utilizing the rotation of pond degree to lead, the ore particle layering that proportion is different wash away light specific gravity realize sorting, also be the production equipment of a kind of noncontinuity of gravity treatment, the recovery that is fit to fine mineral particle sorts, disposal ability is also little.
In the prior art, be applied to more and more and utilize pneumatic separation.For example, a kind of equipment of pneumatic separation is disclosed in China Patent No. " 200710006053.4 ", its applying date is on January 24th, 2007, open day is on July 25th, 2007, by the mineral materials case, the mineral materials outlet, selection by winnowing is simplified, dustproof cloth bag, compositions such as blower fan, its mineral materials case is positioned at the side of selection by winnowing cylindrical shell top by blower fan, mineral materials exports the top that an end is positioned at the selection by winnowing cylindrical shell, the other end links to each other with mineral materials case bottom, blower fan is positioned at an end of selection by winnowing cylindrical shell, blower fan is connected by the fairing air channel with the selection by winnowing cylindrical shell, and another termination of selection by winnowing cylindrical shell links to each other with dustproof cloth bag.For another example, China Patent No. " 200910043118.1 " discloses a kind of novel ore separators, the applying date is on April 13rd, 2009, open day is on September 30th, 2009, comprise flour mill and ore dressing storehouse, the ore dressing storehouse is a hollow container, feeding port and feed pipe are arranged at its top, there are funnel-form discharging opening and fresh air inlet in its underpart, ore dressing is provided with tripper in the storehouse, connects by feed pipe between flour mill and the ore dressing storehouse, all is provided with air-introduced machine on all feed pipes, feed pipe discharging opening in the ore dressing storehouse be in tripper directly over, be serially connected with second ore dressing storehouse on the feed pipe at top, ore dressing storehouse.And for example, the disclosed pneumatic separator of China Patent No. " 200920066117.4 " comprises the ore dressing storehouse, feeding port is arranged at the top in ore dressing storehouse, and funnel-form discharging opening and fresh air inlet are arranged at the bottom, and sidepiece has charging aperture, the charging aperture place is provided with feed pipe, and the feed pipe below is provided with agitator.
But also there is following deficiency in actual applications in existing pneumatic cleaner: one, have only by one-level primary election, cause beneficiating efficiency lower, and treat that ore dressing and impurity are not easily separated, the ore dressing effect is undesirable, and what have passes through multipass sort, but material need utilize wind-force to be transported to the next stage storehouse of selecting materials from one-level ore dressing storehouse, cause material to be selected can not normally enter the next stage storehouse of selecting materials, stop up easily transfer passage, easily sorting not, and have the low shortcoming of beneficiating efficiency equally.Two, ore-dressing technique is long, has increased the ore dressing time, and the device processes ability is little, causes beneficiating efficiency extremely low.Three,, thereby can not realize continuous ore dressing because each grade ore dressing storehouse all needs certain processing time.
