Abstract
The invention discloses dry sand medium preparation process is used on a kind of air dry sand Recognition Applied in Coal Preparation System, step of preparation process is as follows: a, choosing raw material；B, it grinds；C, aqueous magnetic separation；D, it is dried；E, sieve classification；F, mixing is stirred；G, it encapsulates spare.Advantage is: the present invention can improve resource utilization, ore resource is avoided to waste.
Description
Technical field
The invention belongs to coal separation technical field, more particularly, to using dry sand medium on a kind of air dry sand Recognition Applied in Coal Preparation System
Preparation process.
Background technique
Currently, accounting of the iron ore in exploitated ore does not have out then when being lower than 3% or so in the exploitation of iron ore
Value is adopted, directly abandons, causes certain wasting of resources, and iron ore particle is then the important dry sand medium in dry coal preparation,
Therefore the utilization rate of resource can be greatly improved by the iron ore particle in rejected ore being refined processing.
Summary of the invention
It is used on a kind of air dry sand Recognition Applied in Coal Preparation System the purpose of the present invention is in view of the deficiency of the prior art, providing
Dry sand medium preparation process, it has the characteristics that resource utilization can be improved, ore resource is avoided to waste.
To achieve the goals above, the technical scheme adopted by the invention is that: with dry on a kind of air dry sand Recognition Applied in Coal Preparation System
Sand medium preparation process, step of preparation process are as follows:
A, it chooses raw material: choosing ore raw materials of the iron ore content less than 3%；
B, it grinds: ore raw materials being poured into ball mill and is ground, ore particles are obtained；
C, aqueous magnetic separation: ore particles are poured into wet magnetic separation equipment, adsorb mine by the roller on magnetic plant
Armco magnetic iron ore in stone particle, and Armco magnetic iron ore is collected；
D, it is dried: being dried by Armco magnetic iron ore of the ore in sand form dryer to collection, the magnetism after drying
Its moisture adulterated of iron ore is less than 3%；
E, sieve classification: sieve classification is carried out according to the granule size of Armco magnetic iron ore by screening plant, classification is altogether
It is divided into 5 grades, wherein A grades of granularities are 0.35-0.3mm, 0.3-0.25mm, C grades of granularity 0.25-0.2mm, D grade granularities of B grades of granularities
0.2-0.15mm, E grades of granularity 0.15-0.1mm；
F, be mixed: the ore particles after choosing screening are proportionally mixed and stirred for uniformly obtaining spare dry
Sand medium；
G, encapsulate spare: spare dry sand medium encapsulated, in case when coal separation carry out using.
The invention has the advantages that compared with the prior art: the present invention can be lower than 3% mine to iron ore content
Stone is recycled, and which raises the utilization rates of resource, avoids the waste of ore resource.
Specific embodiment
As described below is only presently preferred embodiments of the present invention, is not intended to limit the scope of the present invention.
Embodiment: using dry sand medium preparation process on a kind of air dry sand Recognition Applied in Coal Preparation System, step of preparation process is as follows:
A, it chooses raw material: choosing ore raw materials of the iron ore content less than 3%.
B, it grinds: ore raw materials being poured into ball mill and is ground, ore is ground by the steel ball in ball mill
Mill is crushed, and obtains short grained ore particles after the completion.
C, aqueous magnetic separation: ore particles are poured into wet magnetic separation equipment, and water source is sprayed to it, in wet magnetic separation equipment
It can be adsorbed by roller when roller rotates with magnetic iron ore with magnetic roller, and non-magnetic other ore meetings
It is discharged, when rollers being waited to go to its magnetic force most weak side, iron ore can fall and be collected.
D, it is dried: being dried by Armco magnetic iron ore of the ore in sand form dryer to collection, the magnetism after drying
Its moisture adulterated of iron ore is less than 3%.
E, sieve classification: sieve classification is carried out according to the granule size of Armco magnetic iron ore by screening plant, classification is altogether
It is divided into 5 grades, wherein A grades of granularities are 0.35-0.3mm, 0.3-0.25mm, C grades of granularity 0.25-0.2mm, D grade granularities of B grades of granularities
0.2-0.15mm, E grades of granularity 0.15-0.1mm.
F, be mixed: the ore particles after choosing screening are proportionally mixed and stirred for uniformly obtaining spare dry
Sand medium.
G, encapsulate spare: spare dry sand medium encapsulated, in case when coal separation carry out using.
