双腔颚式破碎机有效破碎空间的研究

Study to Effective Crushing Room of Double-Cavity Jaw Crusher

破碎力的大小及其在破碎腔内的分布情况是破碎机设计的重要依据。本文通过对机构的运动分析找出了动颚速度瞬心的变化规律,阐述了动颚齿板的运动状态,并提出了有效破碎空间的概念,揭示了破碎力的变化规律。

Strength of crushing force and its distribution in crushing room are important basisfor designing double-cavity jaw crusher. The paper finds out variation rule of movingjaw's velocity instantaneous center by analysis to motion of mechanism, expoundsmotion status of jaw board, and offers concept of effective crushing room and disclosesvariation rule of crushing force
