Jaw Crusher nesting population determine the minimum width
Discharge gate size the width of a direct impact on productivity, and power consumption of the crusher wear of broken plate.
Representation of discharge gate width is not uniform at home and abroad. At present, the domestic nesting population is defined as the width of discharge opening in a crusher bottom, when the fixed jaw plate and at the close to the fixed jaw plate (closed), a jaw and another jaw teeth tooth peak between the valleys of the shortest distance. Abroad are generally fixed jaw and jaw are farthest apart (the open edge) represents the width of discharge opening width. In the national standards of the Soviet Union in the Jaw Crusher, which stipulated unequivocally that the width of discharge opening width means the dimensions when open.
Minimum width of the nesting population must ensure that materials in the lower portion of the crushing Chamber does not produce compact, which is not to cause clogging of the nesting population. A reasonable minimum width of discharge opening width can be determined as follows.
Assume that moving jaw for translational motion, and ignored the moving jaw in the swinging of oomyzus sokolowskii angle during impact and material and friction effects on nesting of broken Board asked. Breaking product in free fall under gravity.
Material within the crushing cavity filling density from the gradually increasing, reaches its maximum value at the nesting population. Material within the crushing cavity filling characteristics of density as shown in Figure 2. Feed particle size or the crushing Chamber after being broken in the particle size is unequal. When you go back to the extreme position when moving jaw plate, different materials at the corresponding level of block is biting. Within the occlusal surface, voids between materials with fine material degree of filling may be.
