一、概述螺旋滚筒装煤问题的理论探讨与实验分析,在国内外已有相当深入的研究,螺旋滚筒结构形式的变化,结构参数和工作参数优化的探讨,对滚筒装煤能力的改善已收到了较好的效果,目前对滚筒装煤能力的研究,仍是实验多于理论,由于螺旋滚筒装煤机理非常复杂,影响因素多,理论上很难以数学表达式的计算来评价滚筒装煤能力的高低,如实测可得出某一滚筒的装煤效率,机道浮煤高度与装煤的能耗等,这些性能参数很难从理论计算上确定,因此滚筒的结构参数和工作参数往往是由实验分析来确定合理的取值范围。理论上试图寻求最优参数的种种尝试,限
First, an overview of the spiral drum coal theory and experimental analysis of the problem, at home and abroad have been quite a deep study of spiral roller structure changes, structural parameters and optimization of working parameters of the drum capacity of the coal has been improved To a better effect, the current capacity of the drum coal loading, the experiment is still more than theory, due to the spiral drum coal handling mechanism is very complex, many factors, it is difficult to theoretically mathematical calculations to evaluate drum loading capacity Of the actual measurement can be drawn on a drum of coal charging efficiency, mechanical floatation height and the energy consumption of coal loading, these performance parameters are difficult to determine from the theoretical calculations, the drum structure parameters and working parameters are often The experimental analysis to determine the reasonable range of values. Attempts to seek the optimal parameters in theory attempts, limits
