1.“V” type of crushing chamber, effective opening size is equal to the nominal opening size (common jaw crusher adopts the traditional asymmetric crushing chamber structure, and effective opening size is smaller than nominal opening size)and the throughput capacity will be increased by15-20% compared with the normal crushing chamber.

2.The discharge opening of ASJ-E jaw crusher applies the hydraulic adjusting unit, the optimized chamber and motion parameter make the product have greater through capacity for same clearance.

3.Smaller discharge clearance for same through capacity. The main components of frame adopt high- quality manganese steel, thickening steel plate, and finite element analysis method is used to evaluate mechanical strength in the process of design to improve the load resistance and impact during using. Cold installation process for bearing and thin oil lubrication make service life prolonged and efficiency of the rotation improved.

4.Four humanized maintenance operation units adopted for easily damaged parts of ASJ - E: bolt fastening and spring removal unit, moving jaw maintenance unit, side guard plate removal unit, adjusting seat replacement unit, so maintenance personnel can easily have inspection, maintenance and care with the four units.
