Origin:hsmmac    Date:2012-05-25    Size:Small Medium Big

1, coal gangue crusher without sieve bottom pulverizer hammer shaft are cover by six screws on the edge of the rotor disc, cover such as wear serious, which should be replaced, such as severe wear affects six screws, remove the hammer shaft will cause difficulties;
2, the hammer impact portion of the side is abraded, can replace the other side;
3, as a result of raw material factors, the lower terminal blowdown is not smooth, fine material in the cavity can be repeated grinding out, that the lower load is too large, suggested that the outlet direction of the abdomen below the block liner is removed, the outlet to expand from 50 to 80 cm in diameter, so that the smooth material lighter, lower load;
4, coal gangue crusher without sieve bottom pulverizer in long-term use, such as the need to replace the shaft, bearing, bearing seat and other components, the assembly must maintain a large shaft assembly tongxinfang, correction of bearing seat, hand wheel rotating shaft idling easily, can start test, always pay attention to bearing temperature rise condition;
5, coal gangue crusher non-sieve bottom hammer mill both wear, adjustable four hammer shaft in the rotor disc mounting position (to move outside the eye), continue to use;
6, coal gangue crusher as a result of raw material factors, the material into the feed inlet after unsmooth baiting (not included in colorectal wall case) recommendations can be superior each hammer cross removing one, try again;
7, the equipment assembly or replacement of the hammer head, must maintain the balance of the rotor, each row of the hammer shaft on the total weight of the hammer and hammer shaft corresponding to the total weight of the hammer, the total error not exceeding 100g, single hammer weight deviation not more than ± 0.5 kg;
8, coal gangue crusher without sieve bottom pulverizer without grate bottom, solves the problem of wet material paste, but hammer worn and lining plate between the gap is too large when the particle size becomes coarse, accordingly, is recommended in the outfeed conveyor installed at the end drum sieve, a small amount of coarse material returning to crush, in such a way that the reduction hammer repair times, prolong the service life of the hammer.
