Further, in order to adapt to the magnetic Ore Transportation in the mine that span is comparatively large or landform is comparatively complicated, magnetic Ore Transportation system also comprises the second ribbon conveyer 3 for carrying obliquely, second lower end cylinder 31 of the second ribbon conveyer 3 is connected with generator 4, and the second ribbon conveyer 3 is for being transported to ore dressing plant by being removed the magnetic ore 5 after gangue mineral by dry-type magnetic extractor 2.Second ribbon conveyer 3 potential energy is electric energy is that mine electric network is powered, and makes mine can economize energy further, thus obtains larger economic benefit.
In addition, the first ribbon conveyer 1 and the second ribbon conveyer 3 can start in a variety of forms, and preferably the first upper end cylinder 12 of the first ribbon conveyer 1 and the second upper end cylinder 32 of the second ribbon conveyer 3 are driven by motor in the present embodiment.The first descending ribbon conveyer 1 and the potential energy of the second ribbon conveyer 3 make generator 4 generate electricity, and generator 4 electricity power supply motor or electrical network.
Wherein, motor is connected with upper end cylinder 12 preferably by such as CST drive unit.The No Load Start characteristic of CST drive unit can reduce the starting current of system effectively, shortens start-up time, reduces the impact to electrical network.
Further, the magnetic ore 5 after removing gangue mineral is transported to the second ribbon conveyer 3 again after receiving and coming from magnetic ore 5 that the first ribbon conveyer 1 carries by dry-type magnetic extractor 2.Carry out throwing tail by dry-type magnetic extractor 2 pairs of magnetic ores 5 to sort and can improve milling ore grade, entering broken amount or entering mill amount of magnetic ore 5 can be reduced, thus reduce the energy consumption in ore dressing plant.The first descending ribbon conveyer 1, second ribbon conveyer 3 coordinates with dry-type magnetic extractor 2 and makes mine can economize energy and improve milling ore grade significantly, thus obtains very large economic benefit.
Particularly, dry-type magnetic extractor 2 comprises drive roll 22, magnetic drum 21 and is around in drive roll 22 and the belt on magnetic drum 21, and the installation site of magnetic drum 21 is higher than the installation site of drive roll 22 and the throughput direction of dry-type magnetic extractor 2 is obliquely.By magnetic drum 21, to magnetic ore 5, sorting is carried out to the suction-operated of high magnetic ore 51.Wherein, the cylinder wall of magnetic drum 21 is distributed with the electromagnetic field or permanent magnetic field that produce magnetic force, according to magnetic force producing cause, magnetic drum 21 can be divided into permanent-magnet cylinder and electromagnetic force cylinder, and magnetic drum 21 is preferably permanent-magnet cylinder in the present embodiment.
Dry-type magnetic extractor 2 also comprises cutting plate 23, and cutting plate 23 is arranged at the back lower place of magnetic drum 21 and receives the gangue mineral sub-elected from magnetic drum 21.Cutting plate 23 coordinates with magnetic drum 21 and carries out sorting to magnetic ore 5 and the gangue mineral 52 removed in magnetic ore 5.Wherein, " afterwards " of " back lower place " refers to for the throughput direction of dry-type magnetic extractor 2, the upstream of throughput direction is " front ", and the downstream of throughput direction is " afterwards ", and the back lower place of magnetic drum 21 is the lower position of the side, downstream of the throughput direction of magnetic drum.High magnetic ore 51 in magnetic drum 21 pairs of magnetic ores 5 has suction-operated.Magnetic ore 5 on the belt of dry-type magnetic extractor 2 is when rotating along with magnetic drum 21, first gangue mineral 52 is thrown the side away from magnetic drum 21 of cutting plate 23, and high magnetic ore 51 is adsorbed the bottom continuing to rotate to magnetic drum 21 with magnetic drum 21 by magnetic drum 21, and lose the absorption affinity of magnetic drum 21, high magnetic ore 51 falls the side of the close magnetic drum 21 of cutting plate 23, thus completes the sorting to magnetic ore 5.
Below the embodiment by Baima Iron Mine is described further the utility model.Baima Iron Mine comprises multiple magnetic Ore Transportation system of the present utility model, and wherein No. two magnetic Ore Transportation systems are the longest, the most important magnetic Ore Transportation systems of Baima Iron Mine, its be arranged on and and tunnel, stope, level ground in, means of transportation is lower line mode.First ribbon conveyer 1 of No. two magnetic Ore Transportation systems and the overall length of the second ribbon conveyer 3 are 3400m, bandwidth is 1400mm, belt speed is 4m/s, transport capacity is 2800t/h, by iron ore from absolute altitude be 1903m mountain transfer station, being transported to absolute altitude is transfer station under the mountain of 1568m, and drop is 335m.
And the first ribbon conveyer 1 and the second ribbon conveyer 3 all in the descending process of transport iron ore by potential energy by changing into electric energy, and magnetic ore 5 is when through dry-type magnetic extractor 2, under magnetic field force effect, realize sorting and remove the gangue mineral 52 in magnetic ore, improving the grade of ore.Wherein, the belt bandwidth of dry-type magnetic extractor 2 is 2.0m, and horizontal length is 41m, hoisting depth is 8m, belt speed is 1.8-2.0m/s, and transport capacity is 2800t/h, and the magnetic field intensity in the cylinder table point constituency of magnetic drum 21 is greater than and equals 430mT (milli tesla).
According to statistics, 2-12 month in 2013, No. two magnetic Ore Transportation systems amount to generating 182 × 10
4kWh, calculates by 0.55 yuan/kWh, saves the electricity charge 1,000,000 yuan.1-4 month in 2014, the throwing tail productive rate of dry-type magnetic extractor 2 reaches 8.68%, gangue mineral 27.14 ten thousand tons of dishing out altogether, and throw tail gangue mineral Grade Control 7.82%, the grade of ore improves 0.9-1.0 percentage point.
In summary, the utility model makes mine can economize energy and improve milling ore grade significantly by be coordinated with dry-type magnetic extractor 2 by the first descending ribbon conveyer 1, second ribbon conveyer 3, thus obtains very large economic benefit.
Below preferred embodiment of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
