What Is Rotary Dryer?
During ore beneficiation, a Rotary Dryer should always be available. Rotary dryer, also called drum dryer or dryer drum, is such a machine which is in need. It is a kind of device for heating and drying the material.
During ore beneficiation, a dryer machine should always be available. The rotary dryer, manufactured by our company, is in hot sale. The Cement Rotating Dryer or cement rotary dryer, mainly used in mine beneficiation, building material, metallurgy, chemical industry and other sectors, dries material with a certain humidity and size.
How Does Rotary Dryer Work?
The rotary dryer is made up of a large, rotating cylindrical tube, usually supported by concrete columns or steel beams. The dryer slopes slightly so that the discharge end is lower than the material feed end in order to convey the material through the dryer under gravity. Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer. When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.
This gas stream can either be moving 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 made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated. When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the cement rotating dryer is known as an indirect-heated type.
What Are the Characteristics of Cement Rotating Dryer?
1. The internal adopts assembled structure which has improved the accuracy of the equipment and it is easy to transport and install.
2. According to the characteristics of different fertilizers, we have arranged the second granulation zone reasonably so as to improve the granulation effect.
3. Adopts assembled hoist board so as to exchange heat fully and lower the energy consumption.
4. Temperature induction monitor, uniform vibration and airproof setting, which improves performance and productivity efficiently.
5. The assorted combustion furnace is energy-efficient and has the characteristics of smaller area, easy regulation and it is equipped with greenhouse.
Features of Drum Dryer
As a large drying machine with fine drying effects, drum dryer is mainly used for drying the sand, river sand, quartz sand and artificial sand. Drum dryer features strong productivity, stable operation, strong adaptability and large processing capacity. In addition, it also can be used for drying the mineral powder and coal slag and is the commonly used mining drying equipment in modern industry.
