Coal Self Combustion In Mill

To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness.Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300c.

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
