What kind of fertilizer pellets can rotary drum granulator machine produce?
If you plan to start the industrial fertilizer pellet making for commercial purpose, the rotary drum granulator is an ideal choice. It can fully meet your various requirements for industrial granular fertilizer manufacturing. Such as,
1-30 TPH granular fertilizer making
Whether you start a fertilizer granulation plant in a small or large scale, the drum pelletizer can fully meet your requirements. Because, the equipment is capable of producing fertilizer pellets at an output rate ranging from 1 to 30 tons per hour (TPH), with 5 models.
3-6 mm size fertilizer granulation
In addition, for final size of fertilizer pellets making, the rotary granulation machine can offer you particles of 3-6 mm. This is ideal for both agricultural and industrial applications. How to regulate the particle size from the drum granulation? Only by adjustment of moisture and drum rotation speed.
Round ball fertilizer pelleting
Then, the rotary drum granulator will prepare uniform, round fertilizer pellets for you. This has a that better performance in mechanical spreading in a large scale, and longer storage, slower release, etc. So, your fertilizer making business is more competitive in commercial market.
Organic and compound fertilizer production
As for feeding materials, you can freely choose organic waste, agricultural waste and chemical powder. Namely, the drum granulation equipment can granulate powder of cow dung, chicken manure, biogas making waste, straw, rice hull, NPK, bentonite, mineral waste, etc. Therefore, it is an key equipment for both industrial organic fertilizers granulation and compound fertilizer pellets manufacturing.

How much does a rotary granulation equipment cost?
The cost of rotary granulation equipment varies widely depending on production capacity, material configuration, and automation level. In general, the price ranges from $8,000 to $90,000, making it accessible for both small and large fertilizer plants. You can choose the best one according to your budget.
How does a drum granulator work for fertilizer pellet production?
In general, the rotary drum granulation machine working process is closed related to the design and granulation method employment. This is a wet granulation fertilizer equipment, which mainly makes use of liquid cohesion to facilitate the granulation of powder. Also, the drum rotation plays an important role. Therefore, this process contains the following 3 steps:
- First, the belt conveyor send the powder materials to the drum.
- Then, through a certain amount of liquid, the power material will has excellent cohesion after being wet in the drum body.
- Next, the main motor drives the shaft mesh with the large gear ring, which is key for drum rotation.
- Under the action of drum rotation, the wet powder material will combine with each other and roll into required fertilizer pellets.

Is there automatic liquid spray device for rotary drum granulator machine?
Of course. YUSHUNXIN can offer you customized rotary drum granulation machine with automatic liquid spray machine.
It crosses the rotary drum to atomize water, liquid binders, or even concentrated solutions directly. This controlled addition of liquid increases the surface adhesion of particles, which accelerates seed formation and growth into uniform fertilizer granules.
By adjusting spray pressure, droplet size, and position, you can control the material moisture in the drum pellet making process. So, you can control the granular fertilizer size you produce freely.
Can rotary drum pelletizer operation with fertilizer steam granulation?
In general, for a 1-10 TPH fertilizer pellet making, it is economical to adopts the cold granulation method. Which relies on the material moisture and drum rotation to granulte the powder fertilizer, as mentioned above. It is a simple process with low energy consumption.
However, if you want to start a large scale production of fertilizer in 10-30 T/H faster, inject the steam into the rotating cylinder is an ideal choice. This hot granulation of fertilizer raises the temperature and moisture of materials. Therefore, the powdered fertilizer is softer and easier to agglomerate, which make materials form into rounder and stronger fertilizer granules.
In addition, there are both professional steam inject boiler for drum granulation of fertilizer. Like the liquid spray system, it can help you control the adding of hot granulation steam precisely.
Top 2 rotary drum granulator designs to reduce erosion in fertilizer pellet making
When producing commercial fertilizer pellets in a large scale, equipment durability is one of the biggest concerns. How about the rotary drum granulator machine? Here, YUSHUNXIN developed the drum pelletizer with innovative designs to reduce erosion. Such as,
Dual layer drum body design
The first is the dual layer design of the drum body. Typically, the outer shell of the rotary granulation machine is made from Q235 carbon steel, which provides high mechanical strength and durability. Inside, a rubber lining acts as a buffer against chemical erosion and mechanical impact from continuous material movement. As a result, you will benefit from longer equipment lifespan and fewer maintenance interruptions.
Granulation sticking knocker holes
The second design feature is the use of granulation sticking knocker holes. Because of powder granule making with liquid, some sticky materials may adhere to the drum wall. This will leads to uneven granules and accelerates surface damage. So, we especially design the rotary pellet machine with knocker holes. This mechanical devices can help you dislodge the buildup, keeping the inner surface clean and reducing wear.
What is the layout of organic and compound fertilizer production plants with rotary pelleting machine?
For this, you can choose to using the rotary drum granulator machine only, or combine with other equipment to setup a drum granulation line. With batching machine, compost equipment, mixer, crusher, dryer, cooler and other auxiliary equipment, you can produce quality compound and organic fertilizer for self use or commercial sale. There are customized drum fertilizer pellet plant layout for you.
100,000 tons/year compound fertilizer production line with rotary drum granulator machine
When you plan to setup a 100,000 tons/year compound fertilizer production plant, a SXZGZ-3210 drum pelleting equipment is the best choice. It can granulate complex powder of 15-30 tons per hour. Combing with dynamic batching machine, 22m dryer, 20m cooler, 1800*1700 granule screener, 800 chain crusher, 1800*1700 coater, double bucket packing equipment and other accessories. In this way, you can make complex fertilizer from powder mixture of urea, ammonium chloride, ammonium sulfate, monoammonium phosphate (MAP), diammonium phosphate (DAP), potassium chloride (MOP), potassium sulfate (SOP), etc.
30,000 tons/years organic fertilizer production line with drum granulating equipment
When it comes to 30,000 tons annual organic fertilizer granule making, the SXZGZ-1870 is advisable equipment. Additionally, you need to configuration it with 8030 mixer, 1818 rotary dryer, 1616 cooler, 1560 sieving equipment, 1240 coating machine, 600 chain crusher, and single bucket bagging scale. Besides, because organic fertilizer granule making from composted industrial residue, agricultural waste, animal manure, etc, which has high moisture and sticking together, you need to treat organic waste by compost machine, crusher and powder screening before granule manufacturing.
Except the two production lines, we also provide other lines with different capacity, such as 20,000 t/y or 50,000 t/y, complete sets of equipment for organic or compound fertilizer production can procure from us.
