Experimental Research Of Kinematic Regularity Of Mediums In Ball Mill

Because of the irreplaceable action,a tumbling ball mill is widely used in material comminution of many fundamental fields from 1893 to now.Even if the ball mail is having shortcomings such as large energy consumption,useful to use low-power, severe wear of grinding media, Furthermore, it will be a kind of predominant material comminution devices for a rather long time.The ball mill of process of crushed materials have to achieve,energy and media consumption is impacting by media campaign.So,the research of media campaign is important to improve the efficiency of the grinding,reduce energy consumption and reduce wear and tear of the media.This paper introduces the mail factors of kinematic regularity of mediums,such as medium size,medium charge fraction, the ratio of the rotate speed and medium stage matching.The trajectories of ball is deduction in theory to be connected.The methods of research is introduced simple.Based on this,I design experimental prototype for kinematic regularity of mediums of two-dimensional space and made experimental program specific and feasible for this experimental, the experimental Including Single-diameter steel ball exercise experiment and ball motion experimental ratio.In the experimental of the observer and record,the photo take down the experimental results specific and detailed.Based on the theoretical study of kinematic regularity of mediums and the photoes,this paper takes an ulterior study on the charge motion of a tumbling ball mill.The outstanding work of this paper is as follows:1.By the photos of kinematic regularity of mediums,we can find the regular pattern between media campaign form and medium size,medium charge fraction, the ratio of the rotate speed, article upgrade;2.By research of the different diameter ball in medium stage matching,the paper made the different of ball movement and reason of how to lead to the phenomenon;3.The paper discuss the best motion of kinematic regularity of mediums and how to impact of the law.From the angle of the most important of the impact of media role,the paper also study changes of the angle.The experimental research of kinematic regularity of mediums discuss the affect of grinding law with medium size,medium charge fraction, the ratio of the rotate speed and medium stage matching.The experimental research is important substance such as guiding production,improving efficiency and ameliorating technology indicators.
