Abstract：Taking two kinds of antimony impregnated graphite and one pure graphite seal rings used in medium speed coal mill as samples, the fractal dimensions were calculated by a Matlab program and friction and wear experiments were carried out. The results show that the relative wear rate and friction factors of the non-antimony impregnated graphite are about 10-30 times and 2 times that of the antimony impregnated graphite, respectively. The fractal dimension of antimony impregnated graphite ( about 1.5-1.7) is lower than the non-antimony impregnated graphite (about 1.8). The friction factors and wear loss increase along with the increasing of fractal dimension.
