Description
Technical field
The present invention relates to the ultra-fine wet grinding method of high hardness mineral material, relate in particular to a kind of grinding technics of high purity sub-nano level superfine zirconium silicate powder.
Background technology
Superfine zirconium silicate powder is widely used in building, sanitary ceramics industry, plays milkiness and base substrate whitening effect.The equal import of the high-grade raw materials used zircon sand of superfine zirconium silicate powder, domestic exploitation zircon sand does not all become scale, and recovery process is very big to environmental disruption, and country is to the also strict restriction of the exploitation of zircon sand; And because zircon sand and radioactive substance such as thorium, uranium symbiosis on a small quantity exceed standard the radioactive indicator of zircon sand through regular meeting.So satisfying under the ceramic industry instructions for use prerequisite, reduce use amount, will make ceramic product more green, environmental protection.
The grinding technics of zirconium silicate powder mainly contains at present:
1. the traditional wet ball-milling technology is made mill ball with alumina balls or cobblestone, and specification is generally Φ 8-13mm, and device therefor is common ball mill at a slow speed, and rotating speed is generally 10-20 rev/min, and one is ground to the end until reaching the requirement fineness.This technology General Spherical time consuming is 50-70 hour, and the fineness of zirconium silicate powder product can reach 1.4-1.6 μ.As rethink and improve product fineness then milling time will be above more than 100 hours, and fineness improves limitedly, causes that slurry temperature rises to 100 ℃ in the ball mill, will greatly damage grinding machine, causes in the grinding machine pottery to serve as a contrast and comes off, energy consumption is high.And to cause in the products obtained therefrom oxidation of impurities aluminium to be sneaked into many because of alumina balls wear rate height, product ZrO
2Content drops to 60-63%.
2. dry pulverization process, micro-powder graded technology can be saved dry materials workshop section, but can't be milled to very low fineness, have only through classification, and meal returns mill and reaches the requirement fineness.But cause efficient low, classification is not thorough.In addition, because of zircon sand hardness is high, to the equipment part well damage, replacing, maintenance cost costliness.
3. adopt steel ball to carry out wet ball grinding as mill ball, sour again blanking iron, grinding efficiency is high, and material is levigate easily, but environmental pollution is serious.
4. wet ball grinding, wet classification technology to certain fineness, propose with the wet classification machine zircon sand wet ball grinding with the classification of fine powder slurry, meal slurry recirculation ball milling, so repeatedly.When powdery pulp is milled to 2 μ m when following, the grader classification efficiency is extremely low, and classification misses by a mile; During the slurry classification, must reduce slurry viscosity greatly, increase moisture content and could effectively reach the classification purpose, but after solid content significantly reduced, the coarse particles that needs back to grind was also wanted thickening, greatly influences production efficiency.
Summary of the invention
The objective of the invention is to overcome the deficiency that prior art exists, a kind of grinding technics of high purity sub-nano level superfine zirconium silicate powder is provided.
The object of the invention is realized through following technical scheme:
The grinding technics of high purity sub-nano level superfine zirconium silicate powder (remarks: zircon sand is exactly a zirconium silicate powder after grinding) may further comprise the steps---
1. roughly grind: adopt the wet ball grinding method, select for use Φ 10～Φ 15mm homogeneity zirconium silicate ball to make abrading-ball, zircon sand is milled to 3～5 μ m;
2. mill in: select for use the homogeneity zirconium silicate ball of Φ 1～3mm to make abrading-ball, in the stirring mill of rotating speed 100～300rpm, above-mentioned zircon sand is carried out twice grinding, be ground to 0.8～1.0 μ m;
3. ultra-fine mill: select for use the homogeneity zirconium silicate ball of Φ 0.5～1mm to make abrading-ball, in the stirring mill of rotating speed 500～1000rpm, above-mentioned zircon sand is carried out twice grinding again, be ground to 0.45～0.55 μ m.
Further, the grinding technics of above-mentioned high purity sub-nano level superfine zirconium silicate powder all adds composite polyacrylic acid dipersant in the process of corase grind, middle mill, ultra-fine mill.
Further, the grinding technics of above-mentioned high purity sub-nano level superfine zirconium silicate powder, the addition of composite polyacrylic acid dipersant is 0.5% in said corase grind, middle mill, each process of ultra-fine mill.
Substantive distinguishing features and obvious improvement that technical scheme of the present invention is outstanding are mainly reflected in:
1. carry out carse, medium and small mill respectively, greatly improve grinding efficiency, product energy consumption is significantly reduced;
2. all grinding stages all adopt homogeneity zirconium silicate ball to make abrading-ball, and cost is not high, guarantee that impurity is sneaked into few in the process of lapping;
3. adopt composite polypropylene hydrochlorate to make dispersant, prevent particle agglomeration, improve wet-milling material solid content, effectively improve grinding efficiency, reduce energy consumption for drying;
4. this product can reduce by 20～40% use amounts in the ceramic industry use amount than similar meal product (survey at same granularity instrument: imported product is 1.2～1.3 μ m, and homemade goods is 1.5～1.8 μ m).
