All major mines are showing a large-scale trend. The crushing operation of coal mining faces a severe situation. There is an urgent need for a crushing device with large processing capacity, high crushing strength, high reliability and strict guarantee of the output particle size to meet the current operational requirements. In the process of high output and heavy crushing, the roller crusher has better external structure and working characteristics, so its performance is superior to other crushers. With the continuous development of the times, the requirements for the roller crusher are also increasing. In recent years, new roller crushers have been continuously introduced, with their small size, large processing capacity, long service life and wide range of use. Favored, compared with other crushers, it has a broad market space and development potential. The purpose of this paper is to design a double-tooth roller crusher, design its overall structure, select transmission components and key parts, analyze the stress and calculate and verify it. Finally, draw assembly drawings, component drawings and component drawings. There are 32 figures, 0 tables and 20 references in this paper.
