Abstract
The invention relates to a slag grinding system which comprises a vertical grinder and a bag dust collector. According to the vertical grinder, slag is fed from a feeding port by a feeding device. Hot air is introduced into the vertical grinder from the lower portion by a hot air furnace, and ground powder is blown up and enters the bag dust collector. The slag powder is separated from air through the bag dust collector. The air is exhausted through a chimney. The feeding device comprises a slag bin and a conveying belt. The slag in the slag bin is conveyed into a proportioning bin connected with the vertical grinder by the conveying belt. A metal selector is arranged on the conveying belt. An induced draft fan is arranged between the bag dust collector and the chimney. Part of the air exhausted by the bag dust collector returns back to the vertical grinder along with the hot air furnace. The slag grinding system is used for slag grinding, so that recycling of the slag is achieved, and the slag is prevented from polluting the environment.
Description
Technical field
The present invention relates to slag process field, particularly relate to a kind of slag mill powder system.
Background technology
Ore residue after ore dressing or smelting is referred to as slag.In commercial production, slag plays
Important effect, especially some weight integrated mills.Utilize slag to make refinement and be processed as slag water
Mud, slag micropowder, slag powders, portland slag cement, mineral wool, blast-furnace cinder, granulated blast-furnace
Slag powders, Copper Slag, slag vertical-mill.Save energy consumption.It addition, also due to substantial amounts of open a mine, no
Only result in underground and lack sky, be easily caused earthquake, and slag has certain pollution for air, many
Year is also easily caused respiratory tract disease by slag in mine staff.Resourcization of Mining Solid Waste means to be adopted
Ore deposit and wash, the barren rock that produces during ore dressing stone and mine tailing.Its store up in a large number necessarily cause to air,
Soil, the pollution of water system and harm.Additionally, blast-furnace cinder is alternatively arranged as cast stone, devitrified glass, fertilizer
The raw material of material, enamel, pottery etc..The utilization ways of slag includes being ground into powder, with convenient
The building materials such as brick are become with other materials mixed sintering.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, it is provided that a kind of slag mill powder system, this
Bright for slag pulverizing, thus realize the recycling of slag, prevent slag from polluting environment.
The present invention is to be achieved through the following technical solutions:
A kind of slag mill powder system, described vertical grinder, bag dust collector, described vertical grinder is by throwing
Material device feeds intake from charging aperture, and air stove is passed through hot blast, the powder that will grind from below in vertical grinder
End is blown afloat, and enters bag dust collector, slag powders is separated with air by bag dust collector, and air leads to
Crossing chimney to discharge, described charging device includes slag storehouse, conveyer belt, by conveyer belt by slag storehouse
Slag send into the batch bin that is connected with vertical grinder.
As the preferred technical solution of the present invention, described conveyer belt is provided with metal selector.
As the preferred technical solution of the present invention, between described bag dust collector and chimney, it is provided with air inducing
Machine.
As the preferred technical solution of the present invention, the air that described bag dust collector is discharged, some
Vertical grinder is returned with air stove.
Compared with prior art, the invention has the beneficial effects as follows: the invention provides a kind of slag mill
Powder system, the present invention is used for slag pulverizing, thus realizes the recycling of slag, prevents slag from polluting
Environment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, air stove；2, conveyer belt；3, slag storehouse；4, metal selector；5, dispensing
Storehouse；6, vertical grinder；7, bag dust collector；8, chimney.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing
And embodiment, the present invention is further elaborated.Should be appreciated that described herein specifically
Embodiment only in order to explain the present invention, is not intended to limit the present invention.

Machine 6 is fed intake from charging aperture by charging device, and air stove 1 is passed through hot blast from below in vertical grinder 6,
Mill pulverized powder is blown afloat, enters bag dust collector 7, by bag dust collector 7 by slag powders and air
Separating, air is discharged by chimney 8, and described charging device includes slag storehouse 3, conveyer belt 2, passes through
Slag in slag storehouse 3 is sent into the batch bin 5 being connected with vertical grinder 6 by conveyer belt 2.
As a preferred embodiment of the present invention, described conveyer belt 2 is provided with metal selector 4.
As a preferred embodiment of the present invention, arrange between described bag dust collector 7 and chimney 8
There is air-introduced machine.
As a preferred embodiment of the present invention, the air that described bag dust collector 7 is discharged, have one
Part returns vertical grinder 6 with air stove 1, containing certain heat from the air that cleaner unit 7 is discharged,
Return in vertical grinder 6 with air stove 1, make full use of the heat of remnants, save the energy.
The invention provides a kind of slag mill powder system, the present invention is used for slag pulverizing, thus realizes ore deposit
The recycling of slag, prevents slag from polluting environment.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all
Any amendment, equivalent and the improvement etc. made within the spirit and principles in the present invention, all should comprise
Within protection scope of the present invention.
