Abstract：The coal preparation plants currently tend to use large-sized equipment.To conform to the tendency,the large LWZ1600 ×2400B screen-bowl centrifuge is introduced for the first time at a coking coal preparation plant for coarse clean slime dewatering and recovery,and the dewatering and ash reduc-tion efficiencies of the centrifuge are assessed by testing with a stand-alone centrifuge on site.Test results show that the centrifuge can work with a highest capacity of 128 t/h with the product moisture,dewate-ring efficiency and ash reduction efficiency being 14.80％,70.46％and 9.99％,respectively,which are all up to the designed indicators.
