Combined three cylinder drying machine (also known as a Triple-Pass Dryer or Three-Cylinder Dryer) is a highly efficient and energy-saving drying system. Its unique nested triple-drum design enables widespread application across various industries. The drying process is primarily achieved through the rotation of the drums and the action of internal lifting flights, which ensure thorough contact and heat exchange between the material and the hot air.
Application Field
| Application field | Specific material examples | Advantage |
| Building Materials Industry | Sands (Yellow Sand, River Sand, Quartz Sand, Manufactured Sand), Slag (Blast Furnace Slag, Granulated Slag), Fly Ash, Clay | High processing capacity, low final moisture requirement (typically can be reduced to 0.5%-1% or lower) |
| Power/Metallurgy Industry | Metal Powders, Mineral Powder, Coal Slime, Coal (Anthracite, Bituminous Coal), Coal Gangue | Often utilizes waste heat, requires equipment wear resistance |
| Agriculture and Environmental Protection | Organic Fertilizer (Chicken Manure, Pig Manure, etc.), Sewage Sludge | Handles high-moisture materials with distinctive odors, requires certain equipment sealing performance and corrosion resistance |
| Chemical and Other Industries | Inorganic Minerals (Kaolin, Diatomite, Perlite), Gypsum (Phosphogypsum, Desulfogypsum), Calcium Carbonate, Heat-Resistant Chemical Pellets | Requires no chemical changes in materials during drying, tolerance of high temperatures and flue dust contamination |
