The coal slime dryer dries the coal slime by using the ambient air to dry the coal slime. The coal slime dryer relies on the heat source to transfer the wet coal slime, so the coal slime drying is inseparable from the heat source. The main heat sources of mud drying equipment are: coal, fuel oil, natural gas, steam, biomass particles, etc., and the cost of using different heat sources is also different.

The selection of a suitable heat source for the slime dryer can greatly affect the cost of the overall production line and the quality of the finished product. Therefore, the choice of heat source is very important. Generally, the commonly used heat sources are coal and natural gas. Coal, due to the consumption cost Low temperature is commonly used in heat source materials; while natural gas has the advantages of high heat, stability, and no flue gas pollution, but it is mostly used in places rich in natural gas. Therefore, it is necessary to select the heat source according to the resources of the customer's own area. In areas with rich coal resources, coal can be selected as the heat source, but attention must be paid to environmental protection. Natural gas is more environmentally friendly than coal, so the heat source of the slime dryer should still be adapted to local conditions.
