The drying capacity of coal slime dryer is not only related with the humidity of raw material, but also the kinds of heating source. For raw materials with high water content inside, they will be processed into quite wet pellets if not being effectively dried by coal slime dryer. It is of key importance to select the heating source of sludge dryer. There are many kinds of heating source. In general, fuels for heating the coal slime dryer are coal, oil, natural gas and electricity, etc.

According to the situation of heat-exchange, we can classify it into direct heating and indirect heating. For indirect heating, it is quite low in the thermal efficiency. While, for some plants, this way is quite convenient for central heating. Water steam, generated by heating water in boiler, heats the drying medium through the radiator. While, for the way of direct heating, it is effective in heat utilization and great in thermal efficiency. This way is preferential for making finished products that are not easy to be influenced by dust.

At present, the oil burner is more and more used. Featured in the easy operation, convenient control and low using cost, the oil burner is quite rapid in temperature rise. The selection of heating source for sludge dryer has great relationships with the following factors like investment cost, temperature of hot air, drying quality of raw materials, drying cost, environmental protection, labor strength and level of automatic control, etc. Fote Machinery sincerely welcomes you to come for site visit and inspection.
