The spigot of described spiral classifier higher than described overfall, and is 18 ° of-20 ° of inclination angles.
A wet screening arrangement technology for mine tailing undersize, is characterized in that comprising the steps:
(1) mine tailing ore pulp is fed the vibratory sieve being arranged in factory building eminence;
(2) after shaker vibration screening, the oversize that vibratory sieve sifts out is by sieving upper chute discharging to the upper ribbon conveyer of sieve;
(3) undersize that vibratory sieve sifts out feeds spiral classifier and carries out grading, and high concentration coarse fraction product feeds sand setting ribbon conveyer by sand setting chute, and fine fraction overflow product from flowing into particulate pump pond by overflow pipe, is raised by Pulp pump and sent.
Advantage of the present invention:
The wet screening device of mine tailing undersize of the present invention merely add a spiral classifier, grading can be carried out to the undersize of wet screening, high concentration coarse fraction product is by sand setting Leather Belt Conveyance, fine fraction overflow product is from flowing into particulate pump pond, and raised by Pulp pump pump and give, thus avoid the adverse effect that the running of coarse fraction material to pump bring, reduce pipe wear.Wet screening arrangement technology arrangement of the present invention is simple, and reliable operation, saves production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1 of the present invention.
Detailed description of the invention
The specific embodiment of the present invention is further illustrated below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, the wet screening device of a kind of mine tailing undersize of the present invention, it is characterized in that comprising the vibratory sieve 1 being located at factory building eminence, chute 5 and the lower chute 7 of sieve on the sieve that is connected of the upper and lower of vibratory sieve 1 therewith respectively, ribbon conveyer 6 on the sieve be connected with chute 5 on described sieve, the ore collecting box 8 be connected with chute 7 under described sieve, be located at the particulate pump pond 3 of described ore collecting box 8 bottom, the Pulp pump 4 that is connected of particulate pump pond 3 therewith, be located at the spiral classifier 2 of side, described particulate pump pond 3, be located at the sand setting chute 9 of this spiral classifier 2 side, the sand setting ribbon conveyer 10 that is connected of sand setting chute 9 therewith, described spiral classifier 2 one end is provided with downflow weir, the other end is provided with spigot 14, described downflow weir is provided with overfall 12, and this overfall 12 is connected with described particulate pump pond 3 by overflow pipe 13, described spigot 14 is connected with described sand setting chute 9, described ore collecting box 8 is connected with described spiral classifier 2 by the lower pipeline 11 of sieve.
The spigot 14 of described spiral classifier 2 higher than described overfall 12, and is 18 ° of-20 ° of inclination angles.
A wet screening arrangement technology for mine tailing undersize, is characterized in that comprising the steps:
(1) mine tailing ore pulp is fed the vibratory sieve 1 being arranged in factory building eminence;
(2) after vibratory sieve 1 vibrosieve, the oversize that vibratory sieve 1 sifts out is by sieving the discharging of upper chute 5 to the upper ribbon conveyer 6 of sieve;
(3) undersize that vibratory sieve 1 sifts out feeds spiral classifier 2 and carries out grading, and high concentration coarse fraction product feeds sand setting ribbon conveyer 10 by sand setting chute 9, and fine fraction overflow product from flowing into particulate pump pond 3 by overflow pipe 13, is raised by Pulp pump 4 and sent.
The wet screening device of mine tailing undersize of the present invention and arrangement technology utilize the undersize of spiral classifier 2 pairs of wet screenings to carry out grading, due to varying in size of mineral solids particle, proportion is different, thus sinking speed is in a liquid also different, so after spiral classifier 2 classification, thin ore particle swims and becomes overflow to flow out in water, and rough grain is sunken to bottom land, and released to spigot by spiral classifier 2, be discharged into sand setting ribbon conveyer 10 by sand setting chute 9 and carry.The fine fraction overflow product overflowed from flowing into particulate pump pond 3 by overflow pipe 13, is raised by Pulp pump 4 and is sent, avoid the adverse effect that the running of coarse fraction material to pump brings, reduce pipe wear.For the lower product of Vibration Screen, can carry out effective classification by spiral classifier 2 to ore pulp, sand setting concentration, higher than 80%, meets the concentration requirement that sand setting ribbon conveyer defeated 10 send material.Wet screening arrangement technology arrangement of the present invention is simple, and reliable operation, saves production cost.
