Description
Technical field
The utility model belongs to enrichment plant field of configuration, particularly a kind of semi-autogenous mill hard rock device for self-returning.
Background technology
Along with the development that iron ore beneficiating factory maximizes, Semi-Autogenous, autogenous grinding technology is widely used.Autogenous grinding/Semi-Autogenous technology maturation that becomes better and approaching perfection day by day, it is advanced reliable that autogenous grinding/Semi-autogenous Grinding Technology flow process has flow process, equipment Large Efficient, reduced investment instant effect, no dust pollution, the feature such as grinding flow process is short.The Semi-Autogenous flow process of wet type is greatly simplified than conventional comminution flow process, can save the comminution comprehensive method of investment and producing cost, and can improve working environment, and production technology is to containing mud, ore strong adaptability that water content is large.And the capital construction cycle is short, production operation personnel are less.According to ore soft or hard degree and autogenous grinding work index height, domestic Semi-autogenous Grinding Technology flow process can be divided into Semi-Autogenous (SAG) flow process, Semi-Autogenous+ball milling (SAB) flow process, Semi-Autogenous+ball milling+fragmentation (SABC) flow process at present.Wherein Semi-Autogenous+ball milling (SAB) technological process is simple, and equipment configuration is simple compact, and the investment advantage such as province is extensively adopted by each large ore dressing plant.
Semi-Autogenous+ball milling (SAB) technological process is broken without hard rock, and semi-autogenous mill uses straight line shaker as one section of classifying equipoment conventionally, and straight line shaker is configured in Semi-Autogenous ore discharge section.On sieve, the coarsegrain particle such as hard rock adopts common tape machine to transport main building and after having bad luck, returns semi-autogenous mill on the sealing-tape machine of ore deposit.This configuration hard rock returns to technique and need adopt many sealing-tape machines to have bad luck, and sealing-tape machine need to be promoted to certain altitude simultaneously, has increased sealing-tape machine length, and link is complicated, increases production operation operation and operating cost.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide semi-autogenous mill hard rock device for self-returning, adopts a high inclination-angle rubber conveyer to replace the mode of original many sealing-tape machines, to reduce operation link, reduces investment and operating cost, improves equipment operation rate.
The purpose of this utility model realizes by following technical proposals:
Semi-autogenous mill hard rock device for self-returning, comprise coming ore deposit sealing-tape machine, semi-autogenous mill, add ball bucket, linear vibrating screen and each equipment room be to, ore discharge funnel chute, it is characterized in that described linear vibrating screen is positioned at a side of semi-autogenous mill, giving between the platform of ore deposit of linear vibrating screen sieve upper hopper and semi-autogenous mill configures high inclination-angle sealing-tape machine.
Described high inclination-angle sealing-tape machine adopts the conveyer belt with wave baffle board at its edge and diaphragm plate, and carrying inclination angle is 0-90 degree.Semi-Autogenous ore discharge oversize granularity is greatly about 50mm ~ 12mm, and water content 10% left and right, meets high inclination-angle adhesive tape convey materials technological requirement completely.
Described linear vibrating screen is configured in semi-autogenous mill without motor one side.The upper coarsegrain material of straight line shaker sieve feeds high inclination-angle adhesive tape afterbody horizontal segment, then by high inclination-angle means of transportation, feeds semi-autogenous mill to ore deposit platform, directly returns to semi-autogenous mill.
Certainly the skill of doing over again of the utility model semi-autogenous mill hard rock device for self-returning is as follows: feed the ore of main building by coming ore deposit sealing-tape machine to feed in semi-autogenous mill, add steel ball simultaneously by adding ball bucket.Ore is fed in linear vibrating screen by mine-discharging terminal semi-autogenous mill ore discharge funnel after semi-autogenous mill ore grinding, undersize material is fed in next step operation by the lower chute of straight line shaker sieve, on sieve, bulky grain hard rock feeds high inclination-angle adhesive tape afterbody horizontal segment by straight line shaker sieve upper hopper, then by high inclination-angle means of transportation, feed semi-autogenous mill to ore deposit platform, together by head funnel, return in semi-autogenous mill with carrying out ore deposit sealing-tape machine, complete hard rock and return to autogenous tumbling mill flow process.Can be according to different ore properties in design, the technical data such as screening efficiency and on-the-sieve material water content, the inclination angle number of degrees of choose reasonable high inclination-angle sealing-tape machine (0 ~ 90 °), the relevant parameters such as sealing-tape machine rib type, make it meet technological requirement.
The utility model, by adopting a high inclination-angle rubber conveyer to replace the mode of original many sealing-tape machines, has reduced operation link, has reduced investment and operating cost, has improved equipment operation rate.There is configuration rationally compact simultaneously, take up an area the advantages such as little, stable.
