High energy ball milling experiments according to the principle of mechanical chemistry of the glass batch , and high-energy ball milling powder briquetting experiments . XRD, DSC-TG, images sintering instrument instrument different ball to powder ratio , milling time prepared glass material powder grain size , crystal structure, changes in activity were studied ; compressive strength of bulk variation and influencing factors are analyzed . Grain size , crystal structure , effective temperature coefficient , low temperature eutectic formation temperature , the the glass batch Powder mechano-chemical effect of high energy ball milling process . XRD analysis showed that high-energy ball milling processing glass batch powder particle size decreases , the grain refinement , the effective temperature coefficient increases , quartz crystal amorphous trend , and generate a new phase of gelation Ca2SiO4 . DSC-TG analysis results show that with the increase of ball to powder ratio and milling time , the low temperature eutectic formation temperature and carbonate decomposition temperature were significantly decreased in the experimental range , above the two temperatures were 747.2 ℃ reduced to 635.7 ℃, reduced from 797.8 ℃ to 676.2 ℃ . Block compressive strength of the test results of the experiment showed that the glass after the high energy ball milling with the material powder has a self-bonding ability , with increasing milling time , significantly increased the compressive strength of the block body , the compressive strength of 6.4 MPa maximum . Helps to improve the compressive strength of the blocks , and enhance the activity of the glass batch in the glass batch to add cullet . In this experimental range , the compressive strength of the block up to 7.5 MPa, the low temperature eutectic formation temperature and carbonate decomposition temperature were reduced from 725.7 ℃ to 615.4 ° C , reduced from 751.6 ℃ to 670.2 ℃ . Compared with no broken glass block , the compressive strength increased by 17.2% , the low temperature eutectic formation the biggest decline in the temperature difference of the temperature and carbonate decomposition temperature of 72.5 ℃ and 47.1 ℃ .
