▌What is a single-drum dryer?

Single-drum dryer, also known as a rotary dryer or drum dryer, is a widely used equipment for drying various materials. It uses a rotating cylinder as the drying body, and the material is dried by hot air in the cylinder to remove moisture or solvents in the material.

The working principle of the single-drum dryer is mainly to use hot air (or other heat media) to directly contact the wet material, vaporize the moisture in the wet material by heat conduction, convection, and radiation, and then use the induced draft equipment to discharge the water vapor, so as to achieve the purpose of drying the material.

▌What is the purpose of the single-drum dryer?

Mineral drying: Drying of mineral raw materials such as gypsum, clay, sand, and stone to provide qualified raw materials for subsequent processing and manufacturing.

Sludge drying: In the field of environmental protection, it is used to dry industrial sludge, domestic sludge, etc., reduce the volume, and facilitate subsequent processing and disposal.

Biomass drying: In the field of biomass energy, biomass raw materials (such as straw, wood chips, etc.) are dried to improve their calorific value and combustion efficiency.
