Design and Comparative Analysis of a Frequency-Converted Reciprocating Ore Size Sieve
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.
