本文对延长凤扇磨冲击板的使用寿命,概述了国内外的研究动态。在板面磨损过程中,认为存在着许多磨损因素,并在板面磨损作了探索性的分析和推导:提出了落煤速度、板面煤粒磨损加速度的分布、撞击角和冲刷角的区分,以及煤质坚硬和疏松对板面磨损等等的影响!并阐述了平面和形面两种冲击板面的差异及比较,为板材的选择提供了参考。
This paper extends the service life of the fan plate impact plate, outlines the research trends at home and abroad. In the process of plate surface wear, it is considered that there are many wear factors, and the plate surface wear made exploratory analysis and derivation: the rate of coal falling, the distribution of coal particle abrasion acceleration, the difference of impact angle and erosion angle , As well as the impact of hard and loose coal on the wear of the slab, etc. The differences and comparisons between the two kinds of impact slabs of the plane and the surface are expounded, which provides a reference for the choice of the slab.
