Abstract:
In view of the low production efficiency of the current crushing station, the feeding frequency judged by the actual experience of the manual experience, the factors affecting the crushing efficiency are comprehensively analyzed.The feed frequency, the material level of the receiving bin, the particle size of the feed and the coal quality on crushing efficiency of crushing station are analyzed.A multivariate regression equation between feed frequency, material level, feed size, coal quality and crushing efficiency is established by single factor analysis and multiple regression analysis.Error analysis is performed using regression equation.The results show that the multiple linear regression equation can effectively predict the crushing efficiency.In order to improve the reliability of the crushing station, the statistical analysis of the crushing station operation process is further carried out.Through the analysis of the influencing factors of the operation efficiency of the open pit coal mine crushing station, it provides a theoretical basis for the intelligent control and unattended operation of the crushing process of the crushing station.
