Description
Technical field
The utility model relates to a kind of preparation equipment, especially a kind of sorting mechanism with the big centrifugal ore separator of ore dressing function and 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.
For example, disclose a kind of multistage circle in China Patent No. " 94222503.1 " and shaken ore separators, head motion is arranged, frame, bolster, multistage circular separator plate, parts such as mine-carrying groove, the multipass sort dish is a plurality of coaxial discs that tapering is arranged, curve-like reflex bar and sorting groove are arranged on the dish, separator plate is installed on the bolster, does back and forth circular motion synchronously by rocking arm and head motion, when mineral aggregate and flushing water from Pan Ding to fashionable, shaking under the effects such as current and spring vibration, continuous loose sink-float, heavy mineral is shifted to the concentrate district along the sorting groove, and light mineral flows into tail-box under flow action.
