Abstract
The invention discloses an ore grinding process. The ore grinding process comprises the following steps: coarsely crushing raw ore through a crusher, performing two-stage separation on the coarsely ground ore through a vibration sorting machine to divide into big crushed ores and small crushed ores, returning the big crushed ores into the crusher, and feeding the small crushed ores into a grinder, collecting dust level ore by using an air machine connected with the grinder, screening the large-particle ground mineral by using a screener connected with the grinder, returning the coarse powder ore to a grinder for grinding, and collecting the fine powder ore. The mineral is concentrated and ground for performing the multi-stage grinding step, so that the good crushing effect of the mineral can be achieved to obtain mineral raw materials with different specifications according to different demands, the aims of crushing for a plurality of times and reducing wearing times are achieved, the energy consumption is reduced, and the efficiency is improved.
Description
Technical field
The invention belongs to technique of preparing field, especially relate to a kind of ore grinding technique.
Technical background
In traditional ore-dressing technique, conventionally to pass through multiple tracks fragmentation from the raw ore of mine extraction, then carry out ore grinding and sorting.Traditional ore crushing technique is divided into several operations conventionally, in different factory buildings, carry out respectively, for example raw ore carries out coarse crushing by boulder crusher in coarse crushing workshop, then being transported to screen house sieves, in the time that the qualified grain size content in coarse crushing ore deposit is more, be typically provided with two kinds of operations of prescreening and check screening, prescreening adopts different screening machines conventionally with check screening.Prescreening is carried out in coarse crushing ore deposit first, during on the sieve of sieve, ore deposit is transported in advance, workshop in small, broken bits is broken in being undertaken by intermediate crusher, middle muck returns to screening factory building and carries out check screening, during on the sieve of test sieve, ore deposit is transported to, workshop in small, broken bits undertaken in small, broken bitsly by fine crusher, ore deposit in small, broken bits and middle muck merge the test sieve extension set that turns back to screen house.Under the sieve that sieve and test sieve separate in advance, ore deposit is transported to fine ore bin.
Tradition ore crushing technique coarse smash equipment, screening plant and in, equipment in small, broken bits need to be arranged on different workshops, therefore each stage product need be had bad luck as required between each workshop, has reduced efficiency, has wasted man power and material.And equipment number of units is many, take up an area space large, power consumption is large, invests highly, and cost increases.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of ore crushing technique of saving space, energy-conservation, investment and cost is provided.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of ore grinding technique, comprising: tcrude ore is carried out to disintegrating machine and carry out coarse crushing; Utilize vibrations separator that two-stage sorting is carried out in coarse crushing ore deposit, be divided into large muck and little muck; Large fragment returns to disintegrating machine, and little muck enters pulverizer; Utilize the air engine being connected with pulverizer that dust level ore deposit is collected; Utilize the screening machine being connected with pulverizer that bulky grain comminution of minerals is screened, meal ore deposit is returned to pulverizer and is being pulverized, and collect in fine powder ore deposit.
It is all to utilize circulating conveyer to carry that described large muck and bulky grain are pulverized ore deposit.
Described screening machine is drum-type screen cloth screening machine.
Described little muck weight is less than 1 kilogram.
Described fine powder ore deposit diameter is less than 5mm.
Described dust ore deposit diameter is less than 0.01mm.
Compared with prior art, the beneficial effect having is: mineral are concentrated to pulverization process, carry out multistage pulverising step, make mineral can reach better crushing effect, require to obtain the raw mineral materials of different size according to difference, to realize how broken few mill, reduce energy consumption, improved efficiency.
Accompanying drawing explanation
Fig. 1 is described ore grinding process chart.
The specific embodiment
Embodiment, disintegrating machine is used for raw ore to carry out coarse crushing, thereby obtains coarse crushing ore deposit.In an example of the present invention, boulder crusher can be arranged on the mineral place of production, thereby minimizing is large than the transportation of heavy mineral, will after the rough classification after fragmentation, need to carry by cyclic conveyor.Carry out sorting by jarring machine by rough, weight is greater than the ore of 1 kilogram and will falls into the conveyer belt that returns to disintegrating machine, and satisfactory little muck is sent to next joint by cyclic conveyor; Little muck enters pulverizer, and pulverizer is pulverized little muck, and pulverizer connects air engine, and the dust level ore deposit in pulverizer is collected by air engine, and dust grade particles diameter is less than 0.01mm; And falling into the screening machine of connection, larger particle ore deposit screens; Screening machine is drum-type screen cloth screening machine, and mesh diameter is 5mm; The mineral that are greater than mesh return to pulverizer to be continued to pulverize, and collect in the thin ore deposit filtering out.
