Our company has built a coal sludge drying system in Shanxi. According to the characteristics of high moisture, high viscosity, high water holding capacity and low calorific value of coal slime, a new generation of coal slime drying system has been carefully created. This set of equipment can dry and recycle a large amount of wet coal slime. The heat sources of the equipment are various and multi-level. Dust removal configuration, environmental protection and low consumption, the cost of drying a ton of coal slime is lower.
