Taking a coal washing plant in Indonesia as an example, the coking coal preparation plant with an annual processing capacity of 4 million tons can increase the processing capacity per hour to more than 700 tons, and the power consumption, media consumption, fuel consumption, and water consumption are all reduced. At present, the whole plant ...

The plant will satisfy Ethiopia's coal consumption. Many cement factories complain of local coal impurities having a negative effect on their machinery and inflating their spare parts' expense. Does the coal washing plant solve this problem? Our coal washing plant and the technology employed will solve the quality issue once and for all.
