Rotary drum dryer is one of the traditional drying equipment, and it has reliable running, flexible operation, strong adaptability, and high production capacity. It is widely used in metallurgy, building materials, chemical industry, coal washing, fertilizer, ore, sand, clay, kaolin and sugar. Its diameter is 1000 4000, and the length is depended on the dry requirements. In the center of the rotary drum dryer, increasing the dispersion mechanism can be avoided; The wet material entering into the drying cylinder is repeatedly copied and left off by the copying plate on the cylinder wall, then in the process of falling, the material is broken into fine particles by dispersator. In this way, the contact area increases greatly, and the material fully contact with the hot air, thus the effect of drying is achieved.

The rotary drum dryer is mainly composed of rotary body, lifting blade, transmission device, supporting device and sealing ring. Dry wet materials are sent to hopper by belt conveyor or bucket elevator, and then by hopper feeder the material enters the feeding end through the feeding tube. The slant of the feeding pipe is larger than the natural inclination of the material, so that the material flows into the dryer smoothly. The cylinder of dryer is a rotating cylinder slightly tilted to the horizontal line. The material is added from the higher end, the heat carrier is entered at the low end with the material in reverse contact; there are also heat carriers and materials that flow into the tube together. With the rotation of the cylinder the material is operated by gravity to the lower end. In the process of moving forward, the wet materials can be directly or indirectly heated by the heat carriers, so that the wet materials can be dried and then be sent out by belt conveyor or spiral conveyor to the discharge end.

Gathering biodegradable raw materials in the working area.Lane turner(groove type fertilizer turner) is used for the fermentation and turning of livestock manure, sludge garbage, straw, sawdust and other organic wastes. Under the operation of vertically and horizontally walking gear, the high-speed disc harrows throw the fermentative materials up, then fall to the ground and the material shift. The fermented material is carried away and the space is cleared for the material requiring fermentation. Thus a complete fermentation process is formed.

2. Materials Crushing Semi-wet fertilizer crusher, also called high moisture crushing machine, has two smashing systems, which helps to thin material particles below 3mm. It has a low moisture requirement on raw materials, as the allowable water content could be 35%, especially suitable for fermented organic material. High moisture fertilizer crusher is widely used in organic & bio-organic fertilizer production. 3.Materials Granulating After crushing, materials are transported intorotary drum granulatorby belt conveyor. With the constant rotating of drum, the materials form a rolling bed, and moves along a certain path. Under the extrusion force produced, the materials agglomerate into small particles, which become the core, attaching the powder around to form the qualified spherical granules.

4.Fertilizer Drying Material shall be dried to enterthe 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. Independent air hating system, centralize waste discharge result in energy and cost saving.

5.Fertilizer Cooling Rotary drum coolerremoves fertilizer water and lowers temperature, used with rotary dryer in organic fertilizer and in-organic fertilizer production, which greatly increases cooling speed, and relieves work intensification. The rotary cooler also can be used to cool other powdered & granular materials.

6.Fertilizer sifting Fertilizers are conveyed into the cylinder through the feed end. With the rotating of the cylinder, organic fertilizers are sifted. Larger granules flowing along the slope of the cylinder to move forward, and the materials are screened through different screens for different purposes. The sub-standard fertilizer granules will be transported back to vertical fertilizer crusher for further process, while the finished products are conveyed to fertilizer coating machine, or directly transported toautomatic fertilizer packager.

When it comes to drying solid bulk materials, Baker-Rullman direct heat rotary drum dryer machines have been chosen for their rugged build, ultimate reliability and excellent ROI. Our direct heat rotary drum dryer machines rely on contact between the material and process gas to dehydrate a very broad variety of materials. The unique triple-pass dryer design is recognized for its efficiency, and ability to produce a consistent product output over extended operational periods. In the rotary drum dryer process, combusted gases mix with clean, heated air. The wet bulk material is propelled through the system via a hot gas air stream. The material is continuously lifted by the cylinder flights and showered through the concurrent stream of hot gases. The three full-length interlocked concentric cylinders rotate together to create the highest velocity possible in the inner-pass. As lighter particles quickly lose 60% of their moisture and move out of the cylinder, heavier/denser particles are retained until they also lose 60% of their moisture.

Fertilizer dryers are used to reduce moisture content of all kinds of powder and pellet materials. You can use a Shunxin drum fertilizer dryer in many industries. For your reference, you can use a large capacity fertilizer dryer to dry clay, coal, mineral waste residue, iron powder, and so on. Whats more, rotating drum dryers play an important role in organic and compound fertilizer production line to dry powder or pellet fertilizer.

In powder fertilizer production lines, a rotary fertilizer dryer machine is installed after a crusher machine or a mixing machine. In pellet fertilizer production lines, you should place Shunxin drying equipment after the fertilizer granulator. The main part of Shunxin drying machine is a horizontal cylindrical drum. In the cylindrical drum, there are lots of fins that can scatter materials in the rotating drum. All parts of Shunxin rotating dryer machine are durable, so the fertilizer dryer is high-quality . In addition, the rotary drum drier is a kind of energy-saving industrial drying facility.

Shunxin experts design our rotating drier equipment reasonably and it has lots of stunning features. In the following content, Shunxin will show you some details about the design of our rotary drying machine.

You can not dry your materials only with a cylinder dryer. Shunxin rotating fertilizer dryer need to work with some corollary equipment. These equipment include burner, hot-blast stove, induced draft fan, cyclone dust collector and dust setting chamber.

Burners are the heating devices. Shunxin has two types of burners: gas-burning burner and dual-purpose burner. Gas-burning burner just can burn gas while the dual-purpose can burn both gas and diesel oil.

Hot-blast stove is another heating facility. Unlike Shunxin burners, a hot-blast stove looks like a sealed cubic room. The inner wall of it is covered with fire-clay bricks and the out part is covered with manganese steel plates. Shunxin hot-blast stoves are movable and it is easy to install them. In addition, we can customize hot-blast stoves in different sizes for you.

Induced draft fan is installed at the discharge part of cylinder drum dryer. It can continuously exhaust hot air in the drum drying machine. This is an inevitable corollary machine for drying powder and pellet materials.

You can use a cyclone dust collector to collect fine dust in the drying process. Out of the purpose of protecting environment, youd better equip this machine for your rotary drier. The collected dust will enter into a dust setting chamber.

Shunxin drum driers are energy-saving. They consume less fuel than other kind of industrial driers. The outer part of the cylinder drier equals to an insulating layer. That means the heat in the drum will not radiate out. In this way, the heat loss is less. Thus, Shunxin rotary drying facility is energy-saving.

Among these component parts of Shunxin rotating dryer machines, there are several vulnerable parts. The quick-wear parts include pinions and belts. Generally speaking, you need to change the pinions and belts of your drum dryer machine every half a year. If you maintain them in a proper way, you can use them for a longer time. For your information, you can also communicate with our sales to ask if they can provide you a set of quick-wear parts for free or in quite low prices.

There is no doubt that you should start the heating facilities at the first step. The materials to be dried will be put into the drying cylinder through a conveyor. Under the function of a induced draft fan, the hot air generated by the hot-blast stove or the burner will move quickly in the drying drum. In this process, the material will lose moisture rapidly. During the drying process, some fine dust will appear. You should use a cyclone dust collector to collect it in order to protect the environment. The collected dust will be centralized in the dust setting chamber. Finally, the dried materials will come out of the rotary drier from the discharge port. And the exhaust fan will exhaust air and water vapor out of the drum part.

Shunxin is a professional industrial machinery manufacturer in China. We are capable to supply high-quality fertilizer dryers to you. Apart from rotary drying machines, we also manufacture fertilizer granulating machines, compost turners, fermentation pots, fertilizer mixing machines, automatic packing machines,etc. Want to know more information, you can contact us right now!

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.
