Description
Technical field
The utility model relates to ore deposit and selects field, is specifically related to a kind of magnetic iron ore picking equipment.
Background technology
The main feature of China's iron ore is " poor ", " carefully ", " mixing ", and Iron grade 32%-37% is about lower than world average grade 10 percentage points.Wherein the iron ore of 97% needs ore dressing process, and magnetic iron ore ore dressing is the main body of iron ore dressing always, in China's iron ore concentrate output, and mainly magnetite concentrate.Current magnetite separation technology adopts the other technique of the stage grinding of single low intensity magnetic separation-stage low intensity magnetic separation mostly, this Processes and apparatus is not suitable for the ore dressing of the chromium depleted zone stone of fine-grained disseminated grain, and the rate of recovery of iron is low in iron ore concentrate, be generally less than 70%, iron concentrate grade is low, impurity content is high, is not suitable for the requirement of metallurgical industry high quality burden and energy-conserving and environment-protective.
Utility model content
For above-mentioned weak point, the utility model provides that a kind of structure is simple, the low easy to operate magnetic iron ore picking equipment of energy consumption.
In order to achieve the above object, the utility model have employed following technical scheme: a kind of magnetic iron ore picking equipment, comprises frame, and described frame is provided with feeding warehouse, and feeding warehouse discharge nozzle is provided with the pay-off matched with discharge nozzle;
Described pay-off is by air-supply arrangement, some jet pipes of being connected with air-supply arrangement ajutage, and the mixing tube be connected with jet pipe is formed, and described discharge nozzle is connected with mixing tube;
Described frame is also provided with the conveyor-belt apparatus matched with pay-off;
Described conveyor-belt apparatus comprises and is located at strong magnet drum in frame and driven pulley, around there being conveyer belt on described strong magnet drum and driven pulley;
Described mixing tube port is provided with the fan nozzle matched with conveyer belt; This fan nozzle can mineral aggregate is uniform, dispersion, be injected on conveyer belt fast.
Described frame is also provided with a buncher matched with strong magnet drum, this buncher can regulate the rotating speed of strong magnet drum;
Described frame is also provided with the tailing storehouse and fine fodder storehouse of matching with conveyer belt.
Described strong magnet drum magnetic field intensity is 5000-15000 Gauss.
Described discharge nozzle inner circumferential is shape of threads, can reach spiral to the object in ore deposit, be convenient to breeze and disperse in mixing tube more fully.
Described mixing tube is also provided with load control valve.
Ore-dressing technique of the present utility model is: will pulverize rear magnetic iron ore or the sand iron ore (weathered sandstone of crossing 100 mesh sieves, in sand shape in mining process, containing a certain amount of fine grained magnetic iron ore) breeze feeding feeding warehouse, breeze enters in the mixing tube of pay-off by the discharge nozzle of feeding warehouse, then under the wind-force effect sprayed at the some jet pipes be connected with air-supply arrangement ajutage, again breeze is sprayed onto strong magnet drum front end from fan nozzle, containing magnetisable material (fine ore) by force by strong magnet drum magnetic-adsorption on a moving belt, and run together with conveyer belt, then do not continued to be separated with fine ore by force under the effect of wind-force or inertia by the impurity that adsorbs or granulated slag, until enter tailing storehouse, the fine ore being adsorbed on conveyer belt surface then continues, along with conveyer belt running, until fine ore departs from strong magnet drum magnetic-adsorption, to fall in fine fodder storehouse.
The beneficial effects of the utility model are:
1. the ore dressing pattern that breaks traditions (namely high-intensity magnetic field selects weak magnetic ore deposit, and low-intensity magnetic field selects strong magnetic ore deposit), this technique has overturned traditional ore-dressing technique, selects strong magnetic ore deposit with high-intensity magnetic field.
2. the rate of recovery is high, constant product quality: this technique will pulverize rear magnetic iron ore or the sand iron ore (weathered sandstone of crossing 100 mesh sieves, in sand shape in mining process, containing a certain amount of fine grained magnetic iron ore) breeze is under the action of the forces of the wind, organically combine with strong magnet drum, utilize wind-force to a kind of external force of breeze, non-magnetic impurity is allowed to be separated by force with Iron concentrate, because wind-force is larger, separating effect better (therefore Iron concentrate grade is higher), strong magnet drum magnetic field intensity is high, and absorption that can be fully effective is containing magnetic ferrous powder.
3. refining process is without water, energy-saving and environmental protection: the technique due to this equipment is a kind of blast enclosure dry powder, power consumption is low, without water, after selected Iron concentrate, remaining namagnetic substance can be used for cement plant additive, brickmaking, plantation etc., is convenient to transport, energy-saving and environmental protection.
