Abstract
The present invention relates to a kind of ferroalloy wet crushing grinding method.Operating procedure are as follows: iron alloy surface sprays upper sodium-chloride water solution, grinds to ferroalloy.Its mass percentage of sodium-chloride water solution is 5% ~ 10% in prioritization scheme, and sodium-chloride water solution is seawater.It is improved using the productivity of crushing grinding of the present invention；Sodium chloride composition can form passivation protection film on iron alloy powder surface, reduce the oxidization burning loss on material particles surface, improve yield rate；Reduce grinder wear liner rate, improves product purity；Dust is reduced in workshop where production line when broken, improves the working environment of Work places.
Description
Technical field
The present invention relates to ferroalloys to crush technology field, and in particular to a kind of ferroalloy wet crushing grinding method.
Background technique
The general production procedure of ferroalloy block material crushing grinding powder is as follows:
Step 1: coarse crushing, is exactly that ferroalloy block material is carried out first break, ferroalloy material block product is made to become smaller,
Convenient for next step grinding flour.
Step 2: grinding flour, equipment used herein is different, but principle be it is the same, exactly coarse crushing is got off
Small bits of iron alloy material is regrind, its granularity is made to reach production requirement.
It is had the following problems both at home and abroad when ferroalloy block material crushing grinding produces and processes at present:
(1) sound construction of ferroalloy block material, it is non-breakable；
(2) the small bits of iron alloy material density after coarse crushing is high, is less susceptible to further grind, causes production efficiency low；
(3) during smashing and grinding, pulverizer liner plate and tup serious wear, the powder that liner plate and tup surface abrasion get off exist
Impurity is formed in product, influences the purity of ferroalloy fines；
(4) dust is larger when dry milling attrition process, seriously pollutes environment, endangers the health of worker.
Summary of the invention
The purpose of the present invention is to solve the above problem, provides a kind of ferroalloy wet crushing grinding method, utilizes the party
Method carries out crushing grinding to ferroalloy, and crushing grinding is high-efficient.
To solve the above-mentioned problems, The technical solution adopted by the invention is as follows:
A kind of ferroalloy wet crushing grinding method, which is characterized in that including following operating procedure:
(1) iron alloy surface adheres to sodium-chloride water solution；
(2) ferroalloy is ground.
Optimization, its mass percentage of the sodium-chloride water solution are 5% ~ 10%.
It advanced optimizes, the sodium-chloride water solution is seawater.
The working principle of the invention:
The present invention is to use sodium-chloride water solution pair mainly before crushing grinding ferroalloy material using physical and chemical principle
Ferroalloy material is infiltrated, and the sodium ion and chloride ion to dissociate in sodium-chloride water solution can be attached to surface of material, broken to grind
When mill, under the hot high temperature action of disintegrating apparatus and material friction generation, the sodium ion and chlorine that are attached in ferroalloy surface of material
Ion pair ferroalloy surface of material generates certain corrosiveness, reduces the structural strength of ferroalloy material to a certain extent,
To effectively improve the efficiency of crushing grinding.
The invention has the following beneficial effects:
It can be improved 6% ~ 20% using the productivity of crushing grinding of the present invention.
The iron alloy powder produced using present invention crushing, due to high temperature action, sodium chloride composition can be in iron alloy powder table
Face forms passivation protection film, reduces the oxidization burning loss on material particles surface, improves yield rate.In the production of extrusion welding rod, this
Layer passivation protection film prevents fever foaming from causing to give up it is possible to prevente effectively from iron alloy powder and water glass of binder generation chemical reaction
Product.

Ferroalloy is crushed with crusher first, is then ground with flour mill.
Specific embodiment three:
The seawater 60kg that 500 kilograms of manganeisen surface sprinkling mass contents are 8%, is crushed with crusher first, is then used
Flour mill is ground.
Comparative example:
It is directly crushed respectively with crusher with 500 kilograms of high carbon ferro-chrome, molybdenum-iron, silicomanganese, manganeisen, then with milling
Machine is ground.
Specific embodiment one, two, three and comparative example comparing result:
After actual production, the present invention is compared with comparative example:
(1) output of unit time of the invention improves 6% ~ 20%, and the powder power consumption of unit mass is substantially reduced；
(2) yield rate of powder improves 5 ~ 10% after crushing grinding of the present invention, increases economic benefit；
(3) used grinder wear liner rate reduces by 3.5% during crushing grinding of the present invention, and wear liner particle enters
Material ratio significantly reduces, and alloy powder purity is increased to 99.8% by 98.5%；
(4) dust reduces 90% in workshop where production line when being crushed, and improves the working environment of Work places.
In conclusion the present invention is either in production efficiency, product quality and production environment, all than existing production
Technology is significantly improved.
The basic principles, main features and advantages of the present invention have been shown and described above.The technology of the industry
