Problems solved by technology
However, because the hardness of the crushing roller itself is generally high, it is time-consuming and labor-intensive no matter whether turning, electric grinding or gas cutting is used to treat the poorly worn bosses at both ends, which seriously delays the crushing work and is disposed of at the same time. Some of them not only did not have any crushing effect, but also caused a great waste of materials for the expensive crushing roll material. The above problems became a technical problem for crushing roll manufacturers and users

Embodiment Construction
[0017] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, exemplary embodiments of the present invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0018] Such as figure 1 , figure 2 and image 3 As shown, the crushing roll for easy maintenance includes a main crushing roll section 1, side crushing roll sections 2 are detachably installed at both ends of the main crushing roll section 1, the outer peripheral surface of the main crushing roll section 1 and the side The outer peripheral surface of the crushing roll section 2 constitutes a crushing surface, and th...

The invention discloses a breaking roll convenient to maintain. The breaking roll comprises a main breaking roll section, wherein lateral breaking roll sections are detachably arranged at the two ends of the main breaking roll section, a breaking face is formed by a peripheral face of the main breaking roll section and peripheral faces of the lateral breaking roll sections, and the hardness of the main breaking roll section is larger than that of the lateral breaking roll section. According to the breaking roll disclosed by the invention, minimum abraded positions at the two ends of the breaking roll are replaced by the lateral breaking roll sections with the lower hardness; when the breaking roll is abraded, the lateral breaking roll sections can be independently disassembled to be maintained, a requirement maintenance amount of the residual main breaking roll section is greatly reduced, and time and labor are saved in maintaining the lateral breaking roll sections; meanwhile, the lateral breaking roll sections are made of materials with lower price, so that material cost is reduced; after maintenance, the lateral breaking roll sections are installed again to be used continuously; thus, not only are maintenance time and maintenance strength greatly reduced after the surface of the breaking roll is abraded, but also material waste is reduced, and material cost is reduced; thus, the breaking roll disclosed by the invention has very high popularization value.
Description
technical field [0001] The invention relates to a crushing roller, in particular to a crushing roller which is convenient for maintenance. Background technique [0002] The crushing roller is the main crushing part of the roller crusher. It usually relies on the extrusion force between the two crushing rollers to crush the material. Therefore, the surface hardness of the crushing roller is generally high, and the surface hardness of some crushing rollers can even reach HRC60~ 70. But no matter the surface hardness is high or low, the surface of the crushing roller must be worn after being used for a certain period of time. Because when the crushing roller is working, the particle size of the crushing roller is large and it is easy to pile up and fall to the middle part of the crushing roller to be crushed when feeding. It is more serious and the two ends are lighter, the crushing surface of the crushing roller is relatively flat in the middle, and the bosses are left at th...
