Study on Coarse Slime Separation in Sanjiaohe Coal Preparation Plant

In order to solve the production environment getting worse problems of the heave medium system occurred by the coal quality variation in the coal preparation plant,a plan to have more coarse slime separation systems was provided.Base on the comprehensive comparison on each separation features of the spiral separator,heavy medium cyclones and TBS,in a combination with the actual production conditions of the coal preparation plant,the TBS separation technique was finally selected.The separation results showed that the TBS would have good separation effect on the slime with a particle size of +0.125mm,the ash content was 11.53% and the production rate was 85.10%.
