Feeding Particle Size and Bedding Density Affected to Separation Effect of Teeter Bed Separator

YANG Sheng-lin,ZHU Ai-min(Sino Coal Handan Design and Engineering Company Ltd.Handan 056031,China)  
The paper introduced the separation principle of the teeter bed separator and the problems existed in the actual application and had an analysis on the particle size scope of the separated material,the uprising water current role in the separator and the bedding density of the teeter bed affected to the separation effect.The paper pointed out when the teeter bed separator was applied to separate the fine particle coal,the particle up and low limit value of the feeding material should be controlled within four.During the low density separation,the bedding density should not be only reduced,or the separation effect of the coarse particle material would be poor.The suitable method is to reduce the up rising water current pressure and to improve the density of floatation bedding.
