Study of talcum charging status in parallel plate electrostatic separator based on particle trajectory analysis
|
摘要
Electrostatic separation has been extensively used in mineral processing,and has the potential to separate gangue minerals from raw talcum ore.As for electrostatic separation,the particle charging status is one of important influence factors.To describe the talcum particle charging status in a parallel plate electrostatic separator accurately,this paper proposes a modern images processing method.Based on the actual trajectories obtained from sequence images of particle movement and the analysis of physical forces applied on a charged particle,a numerical model is built,which could calculate the charge-to-mass ratios represented as the charging status of particle and simulate the particle trajectories.The simulated trajectories agree well with the experimental results obtained by images processing.In addition,chemical composition analysis is employed to reveal the relationship between ferrum gangue mineral content and charge-tomass ratios.Research results show that the proposed method is effective for describing the particle charging status in electrostatic separation.
