Abstract
The present invention relates to a combined processing system for super fine powder of steel slag, which is composed of more than one preprocessing system for super fine powder of steel slag and one post processing system for super fine powder of steel slag, wherein the preprocessing system is composed of a super fine pulverizing grading mill, a grader, an auxiliary blower, a main blower, a wind pipe and a cyclone collector, and the post processing system is composed of an HRM type vertical super fine powder mill, a blower, a wind pipe and a cyclone collector. The combined processing system can pulverize, mill and select steel slag integrally and can obtain 325 to 1250 meshes of fine powder and super fine powder. The combined processing system can fully use waste materials to protect ecological environment and is suitable for processing various kinds of metal and nonmetal minerals.
Description
Slag is the waste material that produces during steel production enterprise is produced, bulk deposition gets off, take a large amount of soils on the one hand, serious environment pollution again on the other hand, comprehensive utilization to this waste material, carried out a large amount of research and development both at home and abroad, but all belong to extensive and low value-added utilization, China utility model patent CN2327445Y is in a kind of new texture of vertical centrifugal autogenous mill crushing chamber of bulletin on July 7th, 1999, but it provides a kind of equipment of special disposal slag, and slag is through pulverizing, after grinding and the stage treatment, can form three kinds of products, 325-1250 order fine powder and ultrafine powder, rich iron tailings, meal.And meal can not fully get utilization the slag of treated mistake because its added value is low.
The purpose of this invention is to provide a kind ofly can pulverize the renewable resource slag, grinding, sorting integrated processing, and can form the combined system for processing superfine steel slag powder of suitability for industrialized production.Solve the invar slag muck and put the environmental pollution that causes, improve the slag added value of product, can make slag obtain sufficient recycling simultaneously.
To achieve these goals, technical scheme of the present invention is to realize like this.
Combined system for processing superfine steel slag powder, it is by the ultra-fine preprocessing system of slag, the ultra-fine after-treatment system of slag is formed, form by the steel slag super fine powder preprocessing system more than 1 and a steel slag super fine powder after-treatment system, between preprocessing system and after-treatment system, be provided with worm conveyor and lift.
Owing to adopted above technical scheme; combined system for processing superfine steel slag powder provided by the invention can be pulverized in two closed cycle systems the processing of slag and processing, grinding, the sorting integrated fine powder that obtains and ultrafine powder can reach the 325-1250 order; it is the product that can be used as cement additive and concrete admixture on a large scale; it can make full use of waste material again; preserve the ecological environment, and be applicable to various metals and the processing of non-metallic material ore deposit.
Below in conjunction with drawings and Examples the present invention is described in further detail.
Fig. 1 is a combined system for processing superfine steel slag powder synoptic diagram of the present invention.
Fig. 2 is a structural representation of the present invention.
Fig. 3 is a schema of the present invention.
See Fig. 1, Fig. 2, Fig. 3.
Combined system for processing superfine steel slag powder is by locating behind steel slag super fine powder preprocessing system and the steel slag super fine powder The reason system forms, the steel slag super fine powder preprocessing system by superfine powder graded mill 7, airduct 25, main air blower 9, Pay blower fan 8, grader 10, cyclone collector 11 formations, airduct 25 connects respectively the superfine powder graded mill 7, main air blower 9, pair blower fan 8, grader 10, cyclone collector 11, slag-drip opening 20, steel slag super fine powder After-treatment system is by HRM type vertical type superfine flour mill 19, airduct 25, cyclone collector 11, blower fan 24 Consist of, airduct 25 connects respectively HRM type vertical type superfine flour mill 19, cyclone collector 11, blower fan 24, Between preprocessing system and after-treatment system, be provided with conveying worm 16 and elevator 17. Steel slag super fine powder After-treatment system is by HRM type vertical type superfine flour mill 19, blower fan 24, cyclone collector 11, airduct 25 Consist of, airduct 25 connects HRM type vertical type superfine flour mill 19, blower fan 24 and cyclone collector 11.
Embodiment:
Select 2 steel slag super fine powder preprocessing systems and 1 steel slag super fine powder after-treatment system for use, at first diameter is sent into total hopper 1 less than the slag raw material of 50mm granularity, vibratory feeder 2 through the feed opening place, raw material is sent into lift 3, lift 3 is promoted to 7 meters and raw material is sent to rotary conveyor 4 again, under the effect of scraper plate, raw material is sent into branch hopper 5, again in the superfine grinding classification grinding machine 7 of each steel slag super fine powder preprocessing system sent into raw material respectively by vibratory feeder 6, the crushing chamber of this machine adopts the new texture of Chinese utility model patent CN2327445Y in a kind of vertical centrifugal autogenous mill crushing chamber of on July 7th, 1999 bulletin, in the crushing chamber of this machine by four tups that run up, with the material fragmentation, grinding, material also obtains lot of energy in this process, clash into mutually, friction is ground, air-flow effect in addition, the little eddy current that produces is also to the powder fine grinding, thereby produce a large amount of fine powders and ultrafine powder, then by the static selection by winnowing classification of ultrafine powder classification grinding machine, can material branch after the fine grinding two kinds of products of hanking will be pulverized, a kind of rich iron tailings, a kind of fine powder, rich iron tailings is discharged by the bottom discharge mouth 20 of grinding machine, send into helical feed 20 and deliver to lift 22 again, send into aggregate bin 23 again, fine powder is under draft (negative pressure) effect of paying blower fan 8 main air blowers 9, be evacuated to grading machine 10 through airduct 25, once more by grading machine 10 inner static selection by winnowing and dynamic selection by winnowing, isolate meal and fine powder again, fine powder is delivered to cyclone 11 at main air blower 9 suction functions through airduct 25, meal through close wind cut down to worm conveyor 16 again the 19 pairs of meal of HRM type vertical type superfine pulverizer through deliver to the steel slag super fine powder after-treatment system to lift 17 carry out secondary grinding, obtain fine powder behind the secondary grinding, under blower fan 24 effects, deliver to rotoclone collector 11 through airduct 25 and enter stockyard or vehicle-mounted packing storehouse.This system forms closed cycle system and forms, and environmentally safe also is applicable to the processing of various metals and nonmetalliferous ore.
