Description

An anti-clogging stone crusher

technical field

The utility model relates to the technical field of stone crushing equipment, in particular to an anti-clogging stone crusher.

Background technique

Crushed stone is made of natural rock, pebbles or ore by mechanical crushing and screening, and the particle size is larger than 4.75mm. During the construction of civil engineering, it is necessary to crush stones of different sizes to the required specifications, but the existing crushing equipment has some shortcomings that need to be improved: 1. The distance between the two crushing rollers is small, and the large stones are easy to make the two crushing rollers. Stuck, thus reducing the work efficiency and the service life of the equipment; when the distance between the two crushing rollers is large, the size of the crushed stone is too large, which does not meet the requirements for use, and requires secondary crushing, resulting in low work efficiency. 2. The existing equipment is difficult to crush stones of different sizes, and the scope of application is too small, that is, the existing equipment can only crush gravel of a single specification, and it is difficult to crush stones of different sizes according to actual needs; 3.
