Production Technology of new type coal water slurry with environmental protection and energy saving characteristics

To enhance adaptability of production technology of coal water slurry( CWS) to the feed coal and reduce energy consumption and pollution,the existing problems of production technology in terms of a large amount of delivered dust,low equipment efficiency,high energy consumption and so on were analyzed. Therefore,a new type processing technology of CWS was proposed after years of investigation and experiments. Three specialized equipments were employed to conduct evenly feeding,belt measurement and coal water mixture for different coal types including mixed coal,coal slime,coal blending on a production line of material preparation. In addition,the lump coal breaking and coal slime breaking could be implemented by these equipments. The results showed that the procedure of material preparation had significant advantages such as simple process,less equipments,small land occupation,environmental protection and energy saving.
