Dryer machine: Dryer machine is suitable for a wide variety of products, ranging from granular, powdery and crystalline materials to filter cakes and sludges for the food, chemical and mineral industries.
Application fields: dryer machine is widely used in the field of building materials, metallurgies, chemical industry, cement and so on. It can dry slag, coal powder, mining powder, clay, sand, limestone and so on. It is composed of rotary body, lifting blade, driving device, supporting device etc. The dryer has advantages of reasonable structure, high efficiency, low energy consumption and so on.
Types of China dryer machine: Rotary dryer(Rotary dryers), Limestone dryer, China dryer(China dryers), Cement rotating dryer, Drum dryer 。
Rotary dryer: Rotary dryers are used to remove moisture from material by using hot gases to heat the material and to evaporate the water. Rotary dryers are suitable for drying wide range of materials continuously because it has considerable variation in size and composition.
Rotary dryer is mainly used for dealing with material in large quantities. Due to the reliable operation, operating flexibility, adaptability and large capacity, this dryer is widely used in metallurgy, building materials, food, light industry, chemical industry, coal, medicine and mining industries.
Application of rotary dryer machine:
Rotary dryer machine is used to dry slag, clay, limestone, rotary dryer machine in cement, chemical, metallurgical, building materials industries.
Introduction of rotary dryer machine:
Dryer is also named the drying machine and rotary dryer. Dryer machine mainly consists of rotary body, raw material feeding plate, driving and supporting device, etc
Limestone dryer: This machine can dry many kinds of materials which contain moisture, such as coal, coal slurry, slag, industrial waste and clay stone. They are widely used in building materials, metallurgy and chemical industry.
Cement rotating dryer: Cement rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industry and coal in coal mine, etc. Cement rotary dryer can be widely used to dry various materials and it is simple to be operated.
Cement rotary dryer characteristics: 1 high drying capacity. 2 smooth rotation. 3 low energy consumption. 4 easy operation.
Drum dryer: Drum drying is a method used for drying out liquids; compared to spray drying, drum drying is the more intense heat treatment. The drum dryer is one of our matural products. We have sold many sets of this dryer to Canada, Tunisia, Vietnam and we have gotten the praise from our customers.
China dryers characteristics
China dryer machine has been optimized a lot, which possesses the following characteristics:
1. It adopts assembled structure, which has improved the accuracy of the equipment. It is easy for transport and installation.
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 improve performance and productivity efficiently .
5. The assorted combustion furnace is a type of energy-efficient device and it has the characteristics of smaller area, easy regulation and it is equipped with greenhouse.
Working theory of limestone dryer
Material to be dried enters the dryer, 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 move toward the discharging end from the feeding end (known as co-current flow), or toward the feeding end from the discharging 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 this case, the dryer is called the 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 dryer is known as the indirect-heated type. Usually, indirect heated dryers are used when product contamination is a concern.
Working Theory of rotary dryer:
Rotary dryers consist of a horizontally inclined rotating cylinder. Material is fed at one end and discharged at the other end. In direct-type rotary dryers, hot gases move through the cylinder in direct contact with the material. The cylinder is equipped with flights, which lift the material and spray it down through the hot gas stream.
The indirect heat transfer dryer made by our company is used in building materials, metallurgy, chemical industry, cement plant for drying of limestone slag, coal powder, slag, clay stone. This dryer is made of rotary body, lifting blade, driving device, supporting device and sealing ring.
