Energy Saving 8 tph Rotary Drum Dryer for sand, cement, gypsum
Rotary dryer is used for drying materials with humidity or granularity in the industries of mineral dressing, building material, metallurgy and chemical. Rotating dryer can be used for drying many kinds of materials and with convenient and reliable operation; Therefore, it has been widely used.
Rotary dryer is also called rotary drying machine. The main body is revolving cylinder with a small slope. It is composed of the revolving body, lifting board, driving device, supporting device, and seal rings etc, with the characteristics of reasonable structure, perfect in workmanship, high output, low energy consumption, and convenient operation. Our company can guarantees the quality of products, credibility first, make the free installation and debugging, do the agency for consignment, and complete by quality, service, and price with other factories. At present, it is still widely used in metallurgical, building materials, and chemical industry.
1. Structure of rotary drier
Drier also named as Drying Machine and Rotary Drier.Drier is mainly consist of rotary body, raw material feeding plate, driving and supporting device, etc
2. Application of rotary dryer
Rotary drier is used to dry slag, clay, limestone, It is mainly used for cement, chemical, metallurgical, building materials industries.
3. Working principle of rotary dryer
When rotary Dryer is operating, it shall be in direct contact with heated gas. The dryer consists of a large rotating cylindrical tube. In order to convey the material through the underside of dryer, the dryer should be slanted slightly to ensure that the discharge end is lower than the end of material feed .

Working Principle of Rotary Dryer: Material shall be dried to enter the dryer. When the dryer is rotating, a series of internal fins will lift the material by lining the inner wall of the dryer. When the material reaches certain height to roll the fins back, it will be fell back to the bottom of the dryer, then passing through the hot gas stream as it falls. This gas stream can either move toward the discharge end from the feed end (known as co-current flow), or toward the feed end from the discharge end (known as counter-current flow). The gas stream can be composed of a mixture of air and combustion gases from a burner, and in which case the dryer is known as a direct heated dryer. Alternatively, the gas stream may be made up of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases are not permitted to enter the dryer, the dryer shall be called an indirect-heated type. Indirect heated dryers are commonly used when product contamination becomes a concern.
