摘要
粒度筛分在矿石的加工利用中具有重要意义.本研究设计了一种变频往复式矿石粒度筛分仪,该设备主要由不锈钢支架、变频齿轮减速电机总成、变频器、滑动底座总成、不锈钢粒度筛等系统构成.为验证该筛分仪的性能,运用F检验、t检验与国家标准中手工筛分法测定的结果进行比较,得出F值在1.12～3.80之间、t值在0.27～1.31之间,当置信度P=95%时,F＜F0.05,6=4.28、t＜t0.05,6=2.45.实验结果表明,变频往复式矿石粒度筛分仪与手工筛分的精密度和准确度不存在显著性差异.该设备可操作性强,能大幅度减少人力投入,降低劳动强度,提高检验效率,满足矿石筛分的检测需求.
Abstract
Particle size sieving is of great significance in the processing and utilization of ores.This study designs a frequency-converted reciprocating ore particle size sieve,which mainly consists of a stainless steel bracket,a frequency-converted gear reduction motor assembly,a frequency converter,a sliding base assembly,and a stainless steel particle size sieve.To verify the performance of the sieve,F-test,t-test,and the results of manual sieving according to national standards were compared.The F-values were found to be between 1.12-3.80,and the t-values were between 0.27-1.31.At a confidence level of P=95%,F＜F0.05,6=4.28 and t＜t0.05,6=2.45.The experimental results show that there is no significant difference in precision and accuracy between the frequency-converted reciprocating ore particle size sieving and manual sieving.This instrument is easy to operate,can effectively reduce labor input and intensity,and meet the detection needs of ore sieving.
