Rotary dryer is the most commonly used drying equipment among mining equipment, which is widely used to dry slag, limestone, coal, clay, grain, compound fertilizer, etc., in mining industry, metallurgy industry, chemical industry, building materials, compound fertilizer production and cement industry.
Rotary dryer has many names in the industry, which is often referred to as the rotary drum dryer and rotary dryer machine. It is suitable for drying metallic and non-metallic minerals, the magnetic, heavy and floating concentrate, clay of cement industry as well as coal slime in coal industry.
Comparison of Coal Slime Before Drying and After Drying
The Usage of Rotary Dryer:
Rotary dryer is a kind of drying machine which can handle a large number of materials. Because of its reliable performance, flexible operation, strong adaptability and large capacity, rotary dryer is widely used in metallurgy industry, building materials industry, light industry, chemical industry, coal, mining industry and medicine industry. Rotary drum dryer is generally adapted to granular materials, and it can also be used for drying sticky and paste materials or materials with high water content.
Rotary dryer has the advantages of large capacity, wide application ranges, small flow resistance, large operation ranges, convenient operation, etc. It is commonly used for drying sand, slag, sludge, coal slime, limestone, quartz stone, granular material, powder material, paste material, compound fertilizer, chicken manure and cow dung.
The Classification of Rotary Dryer:
According to the heat transfer between the drying medium and wet materials, rotary dryer can be divided into direct heat transfer rotary dryer (the direct contact and heat transfer between drying medium and wet materials) and indirect heat transfer rotary dryer (the heat required by the drying process is indirectly passed to the wet materials by the cylinder wall). Indirect heat transfer rotary dryer is rarely used due to its low transmission efficiency and complex structure.
