Compared with fine impact crusher ,SBM (swinging jaw break machine ) ′sadvantage is: quality islighter, pact ponent, broken lumen filled with degree isgood, with materials byuniform broken, toblock bottom mandatory move jaw isunloading, launch finished higher, than with specifications productivity offine impact crusher 20-30% higher than the productivity; Material blocks inthe lower have bigger jaws move upand down movement, acube tumbling tothe shape of, reducing the discharged asJane tilting products that position, product quality isbetter. This design isdone for :the feeding port size is250 ×400 mm; Maximum feeding granularity is210 mm; Production efficiency is3-13m 3/h;Eccentric shaft speed is300 r/min; Discharging mouth adjustment range 20mm to60mm; Motor power is 11-15 KW. This design analysis ofthe current development ofthe crushier,the meanings ofresearching the crusher,how the dimensions ofjaw crusher effect onthe performance ofthe broken, calculate and determine the PE250 x400 structure parameters, the design content mainly includes swing jaw,
