However, the surface of the crushing roller must be worn out after the crushing roller is used for a certain period of time, regardless of the surface hardness. Because the crushing roller during operation, the material granularity is great and easily piles up the crushing roller mid portion and is broken when the feeding, the crushing roller's both ends do not bear crushing work basically, so the surface abrasion of crushing roller can take place the edge effect, the characteristics that the centre is comparatively serious and both ends are lighter appear, the crushing face of crushing roller just also shows the middle relatively level and smooth, both ends remain the condition of boss (as shown in fig. 4), because both ends boss makes the counter roller interval unable to adjust for a short time like this, so the serious part of intermediate abrasion can't realize the crushing effect before any more for crushing work can't go on. In this case, reference to the most worn point, i.e., the lowest point, is often adopted, and the portions with lighter wear at both ends, i.e., the boss portions at both ends, are subjected to turning, electric grinding, gas cutting or the like (as shown in fig. 5), so that the crushing surface of the crushing roller tends to be flat, and then the crushing work is continued by reducing the roller-to-roller distance. However, since the hardness of the crushing roller is generally high, the processing modes of turning, electric grinding, gas cutting and the like are adopted for the boss parts at the two ends with poor wear, the time and the labor are wasted, the crushing work is seriously delayed, the processed part does not have any crushing effect, and the high crushing roller material also causes great material waste, so that the problems become the technical problems of crushing roller manufacturers and users.
