Abstract
The utility model discloses a novel ore milling and classifying device. The device is characterized by comprising an ore pulp tank, a sand pump, a linear sieve classifier and a ball mill, wherein the ore pulp tank and the sand pump are arranged on a same platform, and the linear sieve classifier and the ball mill are arranged on another platform; an inlet and an outlet of the sand pump are respectively connected with the ore pulp tank and the linear sieve classifier by pipelines, the linear sieve classifier is connected with the ball mill by a sand return chute, and the lower part of the ball mill is connected with a magnetic separator by a hopper and a chute. With the device disclosed by the utility model, ore pulp which overflows when the ores are milled enters the linear sieve classifier by the ore pulp tank and the sand pump, materials on a sieve of the linear sieve classifier enter the ball mill by the sand return chute to be ball-milled, and materials below the sieve enter the magnetic separator by the hopper and the chute to be magnetically separated. With the device, granularity classification is realized, namely ores are differently processed according to the size of the granularity. The ores are no longer classified according to the ratio of solid granules. An excellent classifying effect is obtained, and factory selecting indexes are improved.
Description
Technical field
The utility model relates to the metal mine ore dressing field, relates in particular to the equipment that improves the grinding machine classification efficiency.
Background technology
What present domestic mine classifier for milling ore adopted substantially is spiral classifier, and its classification efficiency is low, and equipment energy consumption is higher, and maintenance labour intensity is large, production and maintenance cost are high.Particularly when the character of ore be strongly magnetic mineral and weak magnetic mineral mutually alternately or during parcel, weak magnetic mineral must could effectively reclaim with the form with the strongly magnetic mineral intergrowth, that therefore should not grind is meticulous, otherwise weak magnetic mineral can't reclaim.And because the spiral classifier classification efficiency is low, cause that the part mineral are overground even argillization is serious, be unfavorable for the recovery of magnetic mineral, not only cause metal loss, affect sorting index, and because the qualified ore of part granularity enters grinding machine by sand return again, take the dischargeable capacity of grinding machine, thereby cause the reduction of ball-milling treatment amount.
Summary of the invention
Problem to be solved in the utility model provides a kind of novel grind grading device, and it has replaced traditional spiral classifier, has improved the classification efficiency of grinding machine, has improved and has selected factory's sorting index.The recovery that it is conducive to magnetic mineral has improved metal recovery rate, and the treating capacity of ball milling is improved.
A kind of novel grind grading device of the utility model, it is characterized in that: it comprises slime dam, sand pump, straight line shaker grader, ball mill; Wherein, slime dam, sand pump are on the first platform, and straight line shaker grader, ball mill are on the second platform; The import and export of sand pump link to each other with slime dam, straight line shaker grader respectively by pipeline, and the straight line shaker grader links to each other with ball mill by the sand return skewed slot, and its underpart links to each other with magnetic separator by funnel, chute.
Use this novel device, make ore grinding overflow ore pulp enter the straight line shaker grader through slime dam, sand pump, the on-the-sieve material of straight line shaker grader enters ball mill through the sand return skewed slot and carries out ball milling, and undersize material enters the magnetic separator magnetic separation by funnel, chute.Originally novel device has been realized by grading, and namely carry out different processing according to the size of ore grain size, it has replaced by the different classification of mineral solids particle proportion, has obtained good grading effect, has improved and has selected factory's sorting index.Size according to ore grain size is carried out different processing, is conducive to the recovery of magnetic mineral, has improved metal recovery rate, selects factory's comprehensive recovery thereby improve.
Description of drawings
Fig. 1 is the front view of this novel grind grading device;
Fig. 2 is the top view of Fig. 1.
The specific embodiment
From Fig. 1, Fig. 2 as can be known, this novel a kind of novel grind grading device, it comprises slime dam 1, sand pump 2, straight line shaker grader 3, ball mill 4; Wherein, slime dam 1, sand pump 2 are on the first platform 6, and straight line shaker grader 3, ball mill 4 are on the second platform 7; The import and export of sand pump 2 link to each other with slime dam 1, straight line shaker grader 3 respectively by pipeline, and the straight line shaker grader links to each other with ball mill 4 by sand return skewed slot 5, and its underpart links to each other with magnetic separator 8 by funnel, chute.Wherein, the second platform 7 is higher than the first platform 6.
Carry out ball milling for the on-the-sieve material that makes straight line shaker grader 3 can successfully enter ball mill 4, sand return skewed slot 5 is the on-the-sieve material feed openings a little less than straight line shaker grader 3 in the position of straight line shaker grader 3.
Use this novel device, the on-the-sieve material of straight line shaker grader 3 enters ball mill 4 through the sand return skewed slot and carries out ball milling, and undersize material directly enters magnetic separator 8 by funnel, chute.Because the qualified ore of granularity directly enters magnetic separator, can again not enter ball mill by sand return, ore just can not ground very carefully like this, is conducive to the recovery of weak magnetic mineral, has reduced metal loss, has improved sorting index.Simultaneously, the ore that granularity is qualified does not enter ball mill, can not take the dischargeable capacity of ball mill, and the treating capacity of ball milling is improved.
During this was novel, the straight line shaker in the straight line shaker grader 3 was that sieving area is that individual layer linear vibrating screen, the screen size of 1800mm * 3600mm is 0.75 mm * 20mm.In order to satisfy the straight line shaker oversize from the requirement that flow back into grinding machine, need to raise the straight line shaker height, build the mounting platform 7 of straight line shaker grader.Simultaneously, at platform 6 slime dam is set, and a sand pump is installed is carried ore grinding overflow ore pulp.
This novel grind grading device has substituted traditional spiral classifier, improved the ore grinding treating capacity, 1), reduce annual about 50,000 yuan of cost of equipment maintenance improved and selected factory's sorting index, solved the low difficult problem of spiral classifier classification efficiency, concrete economic benefit is as follows:; 2), improve grinding efficiency 10%, more than 100,000 yuan of saving power consumptions; 3), improve and to select factory's rate of recovery 1.8%, reclaim 800 tons of fine powders more, year increase benefit 400,000 yuan;
Add up to: 550,000 yuan.
