Application of Rotary Dryer

Rotary dryers can be widely used to dry various materials, such as metallic and nonmetallic mineral, clay in cement industry and coal in coal mine, etc, and it is quite easy to master the process measures. China is one of the major countries manufacturing dryer and is also the best producer in the world. Especially Henan Hongxing Mining Machinery Co. , Ltd. is one of the best sellers in those companies manufacturing dryer in China. As a professional manufacturer with many years experiences on mining machinery, Henan Hongxing Mining Machinery Co. , Ltd. can produce and supply all kinds of dryer machines, such as Rotary dryer, Limestone dryer, Drum dryer, Cement rotating dryer and so on.

Advantages and Benefits of Rotary Dryer

Reasonable design; high-efficiency; low consumption, energy consumption; easy maintenance; easy operation; quick delivery; solid construction; proven design; customized for every application; best price on the market.

Operating Principle

Materials are sent to hopper of rotary dryer by belt conveyor or bucket elevator, materials enter the barrel installed with slope to horizontal line from the higher side, and hot air enters the barrel from the lower side, and then materials and hot air mix together. Materials go to the lower side by gravity when the barrel is rotating. Lifters on the inner side of barrel lift materials up and down in order to make materials and hot air mix completely, which is designed to improve the producing efficiency of rotary dryer.

Conclusion:

Rotary dryer is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryers can be used for drying many kinds of materials with convenient and reliable operation; therefore, it has been widely used in those industries above.
