Optimisation and Modification of Coarse and Fine Sludge Separation System in Coal Preparation Plant
The existing coarse slurry sorting system of the coal preparation plant has the problems of excessive ash content in the coal concentrate and running coal in the tailings to a certain extent,which affects the quality of the coal concentrate and restricts the production efficiency.Analyse the current situation of coarse coal slurry sorting system in the coal preparation plant,and determine the optimization and transformation scheme of coarse coal slurry sorting system from the aspects of reducing the content of high ash and fine sludge in the coarse coal slurry feed,improving the efficiency of the coarse coal slurry sorting system sorting and desliming,etc.The specific transformation scheme is as follows:adopt 1 set of FX1000 grading cyclone to replace the original 2 sets of φ500 mm sorting cyclone,replace the TBS sorter with TCS intelligent coarse coal slurry sorter,replace the TBS sorter with intelligent vibrating mesh arc sieve,and replace the TBS sorter with intelligent vibrating mesh arc sieve.TCS intelligent coarse coal slurry sorting machine is used to replace TBS sorting machine,and intelligent vibrating arc screen is used to replace striking arc screen.After the field application,the washing effect of the coarse coal slurry sorting system can be obviously improved,and the ash content of the fine coal and the fine coal yield can be effectively reduced,which achieves a better effect of optimisation and transformation.
