Embodiment Construction
[0010] Such as figure 1 Shown, the production technique of superfine fly ash of the present invention comprises the following steps:
[0011] (1) After the microcomputer metering and flow ratio control are carried out in the raw material warehouse 1, the raw material fly ash is put into the air chute 2 of the grinding head according to the set flow rate; (2) The material is conveyed by the air chute 2 of the grinding head into the grinding head The elevator 3 is lifted by the grinding head elevator 3 and enters the ball mill 4; (3) In the ball mill 4, the material first enters the coarse grinding chamber, and in the coarse grinding chamber, the material enters the separation chamber sieve after being impacted by the grinding body with a larger diameter. points, the material that is too coarse is the R of the material 32 If the sieve residue is greater than 8%, it will be sifted out and returned to the coarse grinding bin, R 32 The finer materials with less than 8% screened e...
