mekar jaya technic - rotary dryer
Mesin rotary dryer merupakan suatu alat pengering dengan bentuk drum yang berputar. Drum yang berputar tersebut secara terus menerus dipanaskan dengan tungku atau sumber panas yang lainnya. Alat pengering ini bekerja dengan memasukkan aliran udara panas kedalam drum beserta dengan material yang akan dikeringkan, temperatur udara antara 150 hingga 700 derajat celcius.
Mesin rotary dryer ini sudah sangat popular di dunia industry karena proses pengeringan dari mesin ini jarang mengalami kegagalan baik dari segi kualitas akhir atapun kuantitasnya. Namun sejak terjadi kelangkaan bahan bakar minyak dan gas, teknologi rotary dryer ini mulai dikembangkan agar bisa seiringan dengan teknologi bahan bakar lain yang LEBIH EFESIEN, seperti batubara, kayu, sekam padi, dan lain sebagainya.
Mesin pengering rotary dryer ini sering digunakan untuk melakukan pengeringan terhadap pupuk, gumpalan partikel, granula, dan gumpalan padat yang kesemuanya dalam ukuran besar. Pemasukan dan pengeluaran bahan bahan tersebut dilakukan secara otomatis dan berkelanjutan akibat dari gerakan berputar, gaya gravitasi. Sumber panas pada mesin ini berasal dari uap panas, gas , batu bara dan minyak tanah. Debu hasil rotary dryer ini dikumpulkan dengan alat cyclone dan wet scrubber.

Weve built a reputation on building the best rotary dryers in the industry. All of our dryers are custom designed to suit the unique processing needs of your material. Whether you require low or high inlet temperatures, short or long residence times, counter current or co-current flow, FEECOs design team can design a rotary drum dryer for your application.
Rotary dryers are a highly efficient industrial drying option for bulk solids. They are often chosen for their robust processing capabilities and their ability to produce uniform results despite variance in feedstock.
The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum. As the drum rotates, lifting flights pick up the material and drop it through the air stream in order to maximize heat transfer efficiency. When working with agglomerates, the tumbling action imparted by the dryer offers the added benefit of further rounding and polishing the granules.
All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.
Rotary dryers are known as the workhorse of industrial dryers. They are able to process a wide variety of materials, and can lend a hand in nearly any industry requiring industrial drying solutions. Some of the most common industries and materials in which rotary dryers are employed include:
Unlike direct dryers, indirect dryers do not rely on direct contact between the material and process gas to dry the material. Instead, the rotating drum is enclosed in a furnace, which is externally heated. Contact with the heated drum shell is what dries the material.

rotary dryer | henan deya machinery co., ltd
Rotary dryer is suitable to dry metallic and nonmetallic mineral, clay in cement industrial and coal slime in coal mine,etc. Rotary dryer can be widely used to dry various materials, and it is simple to be operated.
The 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 dryer known as an indirect-heated type. Often, indirect heated dryers are used when product contamination is a concern. In some cases, a combination of direct-indirect heated rotary dryers are also available to improve the overall efficiency(via wikipedia).
rotary drum drying machine | reduce moisture | temperature resistance
Rotary drum drying machine is widely used in organic fertilizer making plants. Its main function is drying different kinds of fertilizer raw materials or final pellets into appropriate moisture content. The rotating drum dryer equipment is a kind of necessary equipment for all kind of organic fertilizer and compound fertilizer producing factories. Using it, the post management of fertilizer products can be much easier and efficient.
Our rotary drum drying machine consists of a rotary drum, lifting plates, transmission, support device and sealing ring.
The dryer mainly is a slightly sloping drum. The fertilizer materials are added from the higher end, the hot flue gas and the material flow into the drum at the same time.
With the rotating of the drum, the organic fertilizer materials will move to the lower end of the rotary drum.
There are many lifting plates on the inner wall of the drum, which can pick up and sprinkle the fertilizer materials down, so that the contact area between the materials and the airflow is enlarged to improve the drying efficiency.
At last, the dried product flows from the bottom outlet to the next procedure.
1. High degree of mechanization brings it larger working capacity. Meanwhile, it consumes lower fuel and when working, it doesnt need people to operate. That can greatly reduce your cost on hiring operators.
2. Our rotary drum drying machine has good characteristics of high temperature resistance, that ensures the high temperature hot air can dry fertilizer materials quickly. And this kind of drying machine is much more efficient than the traditional dryers.
3. The distribution and angle design of the lifting plates are very reasonable, making the performance of the machine more reliable and the operation more stable. Therefore, it greatly improve the heat energy utilization rate and reduce the frequency of material cleaning.
4. It has excellent application to different fertilizer materials such as poultry manure, livestock, mushrooms, straw powder, saw dust and so on. No matter which kind of materials, our rotating drying machine can work well for you.
5. While the fertilizer materials are drying, our drying machine can also sterilize and deodorize them. That not only makes fertilizers with suitable moisture, but also makes them have better quality.
In wet granulation method fertilizer making line, the drying machine is very helpful to dry fertilizer granules. As we know, the raw materials granulated by wet granulation equipment always have high moisture. Before granulating, the materials always need to be dehydrated with about 30% moisture content by the solid-liquid separator machine. But this value is not suitable to the final granules. To bring granules more compact structure and improve their hardness, the drying machine is needed. After drying, its much easier to transport and store the fertilizer granules.
Fresh chicken manure always has high moisture content. Before making them into fertilizer, its very necessary to reduce the moisture content. If you have a small scale factory of making chicken manure fertilizer pellets, you can choose our small drying machine. It can dry 1-5 tons of chicken manure per hour, the power consumption is 7.5 kw/h. Unlike the solid-liquid separator machine reducing the manure moisture content to about 30%, it can dry chicken manure to a very low moisture content at one time. You can make the dried chicken dung into pellets directly by using dry fertilizer granulating machine. With it, the process of your small chicken litter fertilizer plant will be more simple, which can save you a lot of money.
For 5-12t/h complex fertilizer production line, we have medium capacity drying machine can work for you. Its can dry the final compound fertilizer granules. Our customers always use them for limestone, sulphur or npk fertilizer plants. With high working efficiency, it can bring the pellets better hardness, prevent the compound balls from caking. The fertility can be more stable.
We also have large size fertilizer dryer with capacity of 14-18t/h. Excellent working ability makes it only costs 45 kw power per hour. Moreover, our large drying machine is almost suitable for all kinds of fertilizer plants. Using high performance parts and metallic materials, it has stable structure and the revolutionary design prolongs its working life greatly.
