通过对复摆颚式破碎机四杆机构的运动进行分析,建立了破碎机动颚速度瞬心的解析方程式,分析了其变化规律;并以此为依据研究分析了动颚齿板的运动状态,提出了破碎腔有效破碎空间的概念,建立了有效破碎空间系数的计算公式。该研究为复摆颚式破碎机最大破碎力计算公式的建立提供了理论依据。
By analyzing the movement of the four-bar mechanism of the compound pendulum jaw crusher, the analytical equation of the instantaneous center of jaw crushing speed was established and the variation rule was analyzed. Based on the analysis, the motion state of the movable jaw plate was analyzed, The concept of effective crushing space in crushing chamber was put forward and the formula of effective crushing space coefficient was established. This study provides a theoretical basis for the establishment of the formula for calculating the maximum crushing force of the compound pendulum jaw crusher.
