This paper is aimed at the research and design of PG type double toothed roll crusher. This paper firstly illustrates the existing in the development of the industry of our country and crusher, crusher at home and abroad of the development process is introduced; and then the overall scheme design, to demonstrate the program to choose reasonable scheme; after confirming the scheme, on the important parameters calculated, and design of the deceleration device of shaft design, of the main parts of the design, calculation and check; then, collation and analysis of design parameters, see whether meet the requirements of the production. Finally, crushing machine and various structural design and on the subject were summarized in this paper. Key Words: Crusher, double toothed roll crusher, structure design III 目录摘要...............................................................................................................................
