Method of purification mainly uses machine treadle-operated tilt hammer for hulling rice hydraulic beneficiation method（1. Chen Wen is auspicious, the exploitation of porcelain stone under the Eastern Palace of Guo A Ming nonmetallic ore Longyan
Utilize [J] 2001,24 (2):44-45.）With permanent-magnet concentration purifying technique（2. the bright nonmetallic ores porcelain stones refinement purifications of Cao Ze
Experimental study [J] 2017 (1):62-63.）Also all it is to be arrived porcelain stone ball milling using the method for ball milling Deng, the most producer of in the market
Certain fineness（Control is tailed over below 1%）After carry out magnetic separation removal, which results in porcelain stone some colour developing mineral such as black clouds
Mothers etc. are also mixed into product by ball milling refinement together, and some colour developing mineral are probably non magnetic or weak magnetic mineral, use
Magnetic separation process, which is handled, can not also be separated, so that the quality of product reduces.Therefore, how using each in porcelain stone
A kind of characteristic of kind mineral, method that separation colour developing mineral improve product quality from porcelain stone of research, was producing for producer
Product quality increase company benefit is improved in journey to be of great significance.
There is part of the manufacturer by porcelain stone, water and high aluminium ball by 14 currently on the market:7:In 15 mass ratios input 20t ball mills
When ball milling 12 is small, wherein ball-milling medium mass ratio is φ 60mm:φ50mm:φ40mm：φ30mm =1:1.5:2:10；Porcelain stone ball
Ball milling slurry is from flowing to slurry pool after levigateization, is diluted with water the control of ball milling slurry concentration 25 ~ 30%, ball milling refines 200 mesh sieves
Remaining control is below 1%；Then magnetic separation removal processing, result of the test twice is carried out to show：The porcelain stone 1280 after this method is handled
DEG C firing whiteness（Piece）69.1%, porcelain stone sample observation is less than obvious stain, but the technique processing loss is 15% ~ 20%.
Document 2（Bright nonmetallic ores porcelain stones refinement purification experimental study [J] 2017 (1) of Cao Ze:62-63.）Middle use
Technique only carry out screening process with 250 mesh sieve nets and cannot remove biotite completely, product still can be seen obvious black after processing
Point, although the good processing loss of effect is handled as 8 ~ 10% with magnetic separation process, and magnetic separation cost needs about 40 yuan/ton, it is required
Cost is higher.
The content of the invention
It is an object of the invention to provide a kind of method that separation colour developing mineral improve product quality from porcelain stone, in ball milling
Ball-milling medium uses rational grading during refinement, by controlling rational Ball-milling Time in conjunction with rational sieving technology, effectively
Ground improves the quality of product.
Technical problem solved by the invention can be realized using following technical scheme：
A kind of method that separation colour developing mineral improve product quality from porcelain stone, it is characterized in that：Comprise the following steps：
Step 1：Porcelain stone is fitted into ball mill after crushing, carries out ball milling micronization processes；
Step 2：Porcelain stone is diluted with water ball milling slurry after ball milling refines, and then carries out screening process using sieve.
Preferably, in step 1, the ball-milling medium proportioning being equipped with the ball mill is φ 70mm：25 ~ 50%, φ
50mm：25 ~ 30%, φ 30mm：25~50%.
Preferably, in step 1, the time of the ball milling micronization processes is 18 ~ 22h.
Preferably, in step 2, the concentration for being diluted with water ball milling slurry is 10 ~ 20%；Sieve used by screening
Mesh number is the mesh of 325 mesh ~ 500.
The present invention had main steps that using traditional ball-milling technology, and producer only need to be according to the needs of itself product quality, rationally
The grading and control Ball-milling Time of ground adjustment ball-milling medium can meet production needs, and newly-increased input is small, can largely fit
Answer the application demand of different manufacturers；Handled after ball milling refinement by simple sieve sieving technology, you can reach separation colour developing thing
Matter improves the purpose of product quality, largely alleviates the difficulty of later stage magnetic separation removal technique, or after screened processing
Product quality can reach producer's requirement, then the later stage can save the input of magnetic separation removal, method is simple and convenient effectively.
