Description
Technical field:
The present invention relates to a kind of slag copper separation equipment, belong to the slag copper separation technology field in grinding process.
Background technology:
At present, existing mineral processing circuit be two sections of open circuit crushings, two sections of Continuous Grindings, thick two essences three sweep sort flow process.Affected by smelting process, blowing slag magnetic is strong, and is mingled with the bright copper of more bulky grain.Because the ductility of metallic copper is better, be difficult for levigate, cause the constantly circulation accumulation in primary grinding technique of the bright copper of bulky grain, cause the constantly circulation accumulation in primary grinding system of the bright copper of bulky grain, the problems such as grinding efficiency reduction, floating agent dosage increase and tailings grade rising, to production, bring adverse effect, major embodiment in the following areas:
(1) along with the carrying out producing, the wearing and tearing increasing of pump, service efficiency decline, and the time between overhauls(TBO) became 90 days from original 120 days, and when serious, pump stops up, necessary temporary parking maintenance, restriction time in grinding production;
(2) continuous circulation and the accumulation of the bright copper of bulky grain in ball mill causes grinding efficiency to reduce, and Mill Unit treating capacity drops to 4.85t/h by 5t/h, not enough 4.7t/h when serious;
(3) due to the continuous circulation of bright copper, make the bright copper that part is ground meticulously enter flotation operation with ore pulp, the use amount of floating agent rises to 180g/t by 150g/t, and is unfavorable for the recovery of object mineral, causes flotation tailing index to raise approximately 0.04%.
For addressing the above problem, adopt magnetic separation principle to carry out separation to slag copper in raw ore.At present, existing a large amount of ore dressing plants adopt the magnetic plants such as magnetic pulleys to carry out separation to former slag copper both at home and abroad, and as Japanese Bi company adopts dry-type magnetic selection apparatus to carry out separation to former slag copper before ore grinding, the magnetic concentrate grade of acquisition is 40%.But as added magnetic plant before ore grinding, higher to place space requirement, difficulty of construction is large, expense is high, will affect existing technological process and technical parameter simultaneously, therefore adopt magnetic plant unreasonable before ore grinding.
Summary of the invention:
The object of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of simple in structure, cost is low, the set-up time is short, volume can be decided in its sole discretion by need of production, on-the-spot easy for installation, the slag copper separation equipment suiting large area to popularize.
Object of the present invention can reach by following measure: a kind of slag copper separation equipment, it comprises base, it is characterized in that base connects ball mill by support respectively, motor-vibro screen, slag copper separator, send barrow band, the two ends of ball mill connect respectively charging aperture, drum sieve, drum sieve connects motor-vibro screen, slag copper separator is located at the top of motor-vibro screen, electric vibrating screen is located at the top of sending barrow band, send barrow band to connect charging aperture, slag copper separator comprises triangular supports, three angles of triangular supports connect respectively 3 rollers, 3 rollers are provided with vee belt, triangular supports is provided with pallet, pallet is provided with strong magnets, wherein 1 roller connects motor.
The present invention can produce following good effect compared with the prior art: the present invention is provided with electric vibrating screen and slag copper separator after ball mill and drum sieve.Grinding machine ore discharge sieves through drum sieve, undersized product feeds one section of cyclone classification, on sieve, product enters slag copper separator by electric vibrating screen, realize slag copper separated, efficiently solve the problem existing in magnetic plant and production is installed, and cost is low, the set-up time is short, volume can be decided in its sole discretion by need of production, on-the-spot easy for installation, suit large area to popularize, its tool has the following advantages:
1, improve grinding efficiency, increase the ore handling capacity in the production cycle, through the statistics of a production cycle, adopt after slag copper separation equipment of the present invention, ore handling capacity increases by 5% on the original basis; Meanwhile, the time between overhauls(TBO) of pump was increased to 130 days by 90 days before transforming.
2, improve metal recovery rate, according to assay, use after slag copper separation equipment of the present invention, in slag copper mixture, the separation rate of copper is up to 95-98%; According to the statistics of a production cycle, metal recovery rate more originally improved 0.31-0.47% simultaneously, and floating tail index reduces 0.03--0.05%; Floating agent dosage is reduced to 150g/t by 180g/t.
3, rationally utilize space, place, workshop, keep original technical parameter and installation dimension constant.
4, this principle of device and making are simple, and raw material are easy to obtain, and cost is lower, and the set-up time is short, and volume can be decided in its sole discretion by need of production, and during installation, without the former grinding machine of dismounting, scene is easy for installation simply.
5, safety and environmental protection, during work, noise is less, and site environment is clearly better.In use procedure, do not produce any pollution.
6, reduce maintenance of equipment frequency, save standby redundancy.
