Abstract：To increase the mixture concentration of char,the coal water mixture for gasification was prepared using char and lignite as raw materials.The slurry characteristics were tested by means of traditional process,classified grinding and gap-graded process.The results show that the highest concentration of char and lignite are 55.58％ and 47.38％ respectively prepared by traditional process.The highest concentration of char and lignite are 58.13％ and 51.59％ respectively of slurry prepared by classified grinding process with a thickness ratio of 85 to 15.As well,the highest concentration is 61.36％ prepared by gap-graded process with mass ratio of char and lignite of 7 to 3 and char thickness ratio of 6 to 4.It meets the design requirements that improves fluidity and stability obviously.
