Jaw crusher movement characteristics analysis

Jaw crusher for crushing the materials mainly through dynamic jaw plate and the realization of the relative movement of the jaw plate, which mainly depends on the movement rule of moving jaw, so the study of dynamic jaw movement characteristics is very necessary, and by changing some parameters to make the moving jaw movement more accord with the actual needs, it is very important also, these variable parameters can be hung, such as height, crank length, dynamic Angle to adjust one or several parameters of these parameters, can provide a design space, can point to the region were analyzed, and through the analysis to get a can break the design area In fact, the compound pendulum jaw crusher is structurally matters rod mechanism, and it is a crank rocker mechanism, can be seen from the trajectory of the crank rocker mandibles crusher, jaw crusher there are both horizontal stroke and vertical travel, its trajectory is essentially closed similar oval shape, and the more near the discharging mouth, the flat

Jaw crusher broken good or bad depends on the performance of an important factor, that is moving jaw schedule feature values, if use S for the level of the moving jaw, with the h to represent the dynamic vertical travel, m to show its characteristic value, then stroke feature values can use formula m = h/S Usually at the top of the moving jaw broken is single grain materials, grain is compared commonly big, and large particles materials when its broken need large amount of compression, which would require the horizontal stroke, the stroke feature values, beneficial to the broken material A broken space at the bottom of the moving jaw is compared commonly small, if the material is not discharge in time, may cause material blockage, which requires the moving jaw discharging mouth vertical travel, because of the large vertical stroke to material discharge, namely the stroke feature values, the discharging mouth of the vertical stroke is bigger than trip into the material mouth But whether it’s in the material mouth or the discharging mouth of the moving jaw stroke shoulds not be too little and too much into the material mouth its value is too small, the horizontal stroke will exceed that required by the material crushing compression, cause unnecessary energy consumption At the discharging port its value is too large, will cause the led board too fast grinding, reduce its service life We mainly discuss the multiparameter adjustable jaw crusher, through the above analysis we can see out of the jaw of the stroke feature value is more important, this is the type of crusher provides basis for the design, namely: the design of the crusher, by regulating some or some parameters can make the moving jaw stroke feature values to achieve the ideal value So understand the hubei type broken mobile jaw movement features of design parameters can be adjusted more jaw crusher is particularly important
