In order to improve the working performance of jaw crusher,we insist on improving the equipment structure and performance,focus on the study of jaw crusher stroke feature,let's get to know jaw crusher stroke feature.
Single toggle jaw crusher moves around the locus of points on the jaw suspension point rotating arc, the arc length gradually increase along the inlet into the discharging mouth.Compound pendelium jaw crusher moves around the locus of plane motion, its motion is closed curve,its track is round around the inlet mouth,track becomes more and more flat and straight when it is close to outlet mouth.Horizontal stroke is the displacement of moving jaw along the horizontal direction and vertical stroke is the displacement of moving jaw along the vertical direction,stroke feature is the ratio of horizontal stroke and vertical stroke.
Effect on equipment performance
Horizontal stroke produces necessary amount of compression materials crushing needed, as bigger block requires more amount of compression,so the horizontal stroke should decrease from the inlet mouth to the outlet mouth.Because the materials fall free out from outlet mouth,so horizontal stroke of the outlet mouth should take the discharge height of layer nesting material into consideration.2.Vertical stroke comes from relative motion in vertical direction between the moving jaw plate and the fixed jaw plate,thus can crush and grind material,discharge material down to the bottom, but the cruhsing and grinding reduce the service life of moving and fixed jaw plate,stroke feature can be used to measure the performance of jaw crusher.
