How to choose between a rotary drum granulator and a disc granulator?

In the fertilizer, feed and other industries, disc granulators and rotary drum granulators are both common granulation equipment, playing a key role in fertilizer production lines. Understanding their differences can help companies choose the right equipment and achieve efficient production.  From the working principle, when the disc granulator tilts the disc and rotates, the material continues to roll and agglomerate under the action of gravity, centrifugal force and friction. First, small particles are formed at the bottom of the disc, and then they continue to roll, absorbing the surrounding powder and gradually become larger. After reaching a certain size, they overflow from the edge of the disc to complete the granulation. The material of the rotary drum granulator rolls continuously in the rotating drum, and through water or steam, the basic fertilizer and other materials are fully reacted chemically in a wet environment, and the particles are agglomerated into balls under the extrusion force generated by the rotation of the cylinder. ​

In terms of equipment structure, the disc granulator is relatively simple. The core component is the tilted granulation disc, which is driven to rotate by the drive device. There are also disc inclination adjustment mechanisms, racks, feeding pipes, liquid sprayers, hanging plates, etc. The rotary drum granulator has a complex structure. The main body is a huge rotating cylinder, which is driven by a drive device. In addition, there are feeding systems, steam or gas supply systems, discharging systems, and complex control systems and auxiliary equipment such as temperature and humidity sensors. ​

The two have different focuses in their application areas. The disc granulator has a small investment and is easy to operate. It is a powerful assistant for small production plants and is widely used in small compound fertilizer plants, feed processing plants and small biomass fuel enterprises. The rotary drum granulator is like an industrial giant with high output and is suitable for large-scale production. It performs well in large-scale compound fertilizer and feed production enterprises and industrial raw material granulation processing. ​​

Disc granulators and rotary drum granulators have their own advantages and disadvantages. Enterprises must make comprehensive considerations and careful choices based on their own production scale, material characteristics, product quality requirements and budgets to win development opportunities in the fierce market competition.

How chicken manure is turned into fertilizer and the equipment used

The large amount of chicken manure produced by chicken farms every day was once a headache for farmers – it piled up and occupied land, the odor disturbed people, and polluted the environment. Today, with the upgrading of environmental protection technology, chicken manure has transformed into high-quality organic fertilizer, and this “gorgeous transformation” is inseparable from the help of professional processing equipment.

The core of chicken manure turning into fertilizer is composting and fermentation. Fresh chicken manure contains a lot of pathogens, insect eggs, and a strong smell of ammonia nitrogen. Direct use will burn the roots of crops and attract pests and diseases. Therefore, the first step is to “disinfect and improve the quality” of chicken manure.

First, send the chicken manure to the dewatering machine to remove excess water. The dehydrated chicken manure cannot be fermented directly, but must be matched with straw and sawdust to adjust the air permeability and make the fermentation more complete.

The mixed materials are sent to the fermentation area, and the turning machine (such as the compost turning machine) is on the scene to turn the materials regularly to ensure sufficient air, so that the upper and lower layers are heated evenly to ensure the fermentation effect.

The fermented materials are crushed and agglomerated by a pulverizer, and the impurities are removed by a drum screener machine. The powdered organic fertilizer obtained can be used directly. If you want to improve storage stability and application convenience, you can perform granulation.

Granulation requires an organic fertilizer granulator to condense the powdered material into uniform particles. Granular fertilizer is not easy to absorb moisture and agglomerate, and it is resistant to loss during transportation and storage. When applied, the amount can be controlled to prevent waste. It can also slowly release fertilizer in the soil, prolong fertilizer effect, and improve crop absorption efficiency.

This system not only solves environmental problems, but also creates profits. Chicken manure organic fertilizer improves soil, improves the quality of fruits and vegetables, and is very popular.

From waste to “hot cakes”, the counterattack of chicken manure is clear. Choose professional equipment to turn chicken manure into treasure, protect green waters and green mountains, and collect gold and silver mountains. This is a wise choice for the circular development of modern agriculture.

The Core Value of Granulators in Fertilizer Production Lines

Among the numerous pieces of equipment in a fertilizer production line, granulators are a key link in transforming raw materials into finished products, directly determining the fertilizer’s physical form and performance.

The primary function of a granulator is to process evenly mixed raw materials into granules of a specific size. Direct application of crushed and blended powdered raw materials can easily lead to problems such as clumping and flying. Granulators, however, use processes such as extrusion, rolling, or spraying to agglomerate the raw materials into 3-5 mm granules. This form facilitates transportation and storage, reduces waste, and controls the rate of nutrient release into the soil, preventing nutrient loss and improving nutrient utilization. For example, in compound fertilizer production, granulators precisely encapsulate elements such as nitrogen, phosphorus, and potassium, ensuring balanced nutrient release.

Granulators play an irreplaceable role in improving fertilizer quality. High-quality granulation equipment ensures uniform granules with a moderate hardness, neither too hard to break down nor too soft to cause pulverization. Take organic fertilizer as an example. In organic fertilizer production lines, the continuous temperature and pressure during the granulation process further kill pathogens and insect eggs in the raw materials, reducing the risk of crop disease. It also allows the organic matter to more tightly bind with the auxiliary materials, extending the fertilizer’s effectiveness.

Granulators are equally important for improving production efficiency. Modern equipment enables continuous operation, processing several tons of raw materials per hour. Combined with screening machines, they can separate unqualified granules in real time for secondary processing, reducing waste. Compared to traditional manual granulation, mechanical granulation reduces labor intensity and can be controlled through parameter adjustments to maintain stable quality, meeting the needs of large-scale production.

From an ecological perspective, granulators contribute to environmentally friendly fertilization. Granulated fertilizers reduce dust pollution and prevent powder drift. The slow-release granule design reduces the risk of soil compaction and water eutrophication caused by over-fertilization, supporting green agriculture.

Thus, granulators not only shape the fertilizer form but also safeguard its quality, occupying an unshakable core position in the fertilizer production line.

The difference between organic fertilizer and chemical fertilizer

Difference between organic fertilizer and chemical fertilizer
Chemical fertilizer, manufactured by chemical or physical methods, containing one or more nutrient elements for crop growth. Also known as inorganic fertilizers, including nitrogen, phosphate, potash, micronutrients, compound fertilizers, etc. It has strong pertinence and quick effect. There are many kinds of chemical fertilizers, the most common ones are urea.

Organic fertilizer is formed by a variety of animal, plant residues or metabolites after a certain processing technology. Mainly including agricultural wastes, livestock manure, industrial wastes, municipal Sludge,etc. Organic fertilizer is rich in nutrients and can improve soil.

Cow manure organic fertilizer production line

The cow manure organic fertilizer production line uses crops such as straw and rice bran as fillers, and then sprinkle the biological strains through the turner. It is turned over once every 1-2 days. It can be completely decomposed in 7-10 days and made into a national standard organic fertilizer.

cow manure organic fertilizer production line

The technical route for the production of organic manure from cow dung includes two major steps: raw material aerobic composting process and commercial organic fertilizer fertilizing process.

Among them, the aerobic composting process is used in the fermentation process. Modern aerobic composting is a method in which the manure is used to stabilize and harm the cow dung under aerobic conditions by using aerobic microorganisms, and then converted into high-quality fertilizer. Before the composting, the cow manure raw material is pretreated to meet the fermentation conditions such as water and carbon-nitrogen ratio.

In the fermentation process, the compost turning machine is used to turn over and accelerate the fermentation speed. After composting, the cow manure can be fermented and then enter the fattening process. According to the need, it can be further processed into powdery organic fertilizer and granular organic fertilizer products, or mixed with chemical fertilizer to make various organic and inorganic compound fertilizer products to realize commercial production. .
