ABSTRACT
Currently ，the type of the crusher is multitudinous in domestic, mainly including jaw crusher, hammer crusher, cone crusher, impact breaker and roll crusher. Compared with fine impact crusher ，SBM（swinging jaw break machine）′s advantage is: quality is lighter, less compact structure component, broken lumen filled with degree is good, with materials by uniform broken, to block bottom mandatory move jaw is unloading, launch finished higher, than with specifications productivity of fine impact crusher 20-30% higher than the productivity; Material blocks in the lower have bigger jaws move up and down movement, a cube tumbling to the shape of, reducing the discharged as Jane tilting products that flake composition, product quality is better.
This design is done for：the feeding port size is 1200 x 1600mm; Maximum feeding granularity is 1100mm; Production efficiency is 400-800t/ h; Eccentric shaft speed is 160r/min; Discharging mouth adjustment range 300mm to 400mm; Motor power is 132KW. This design analysis of the current development of the crushier,the meanings of researching the crusher,how the dimensions of jaw crusher effect on the performance of the broken, calculate and determine the PE1200 x 1600 structure parameters, the design content mainly includes swing jaw, eccentric shaft, pulley, seing jaw gear plate, and settled jaw gear plate and frame and some other important components; In addition, jaw crusher principle and characteristics and main component function is introduced, including insurance device, adjusting devices and frame structure, lubrication device, etc.; Also on the machine parameters (spindle speed, production capacity, crushing strength, power) calculate as well. In addition, the significance of broken, crushing process and calculation of crushing ratio, jaw crusher main component installation, operation and maintenance are introduced.
