Drum Granulation Process in Fertilizer
When you want to build a large-scale organic fertilizer or compound fertilizer production line, in addition to the compost turners, the first consideration is the granulator. So which pelletizer is suitable for a high-volume manufacturer? The answer is the rotary drum granulator. The rotary drum granulator can achieve the maximum output of 30 t/h. It sounds incredible. In fact, the drum granulator is one of our best-selling granulators. What makes the rotary drum granulators so hot?

Where is the Main Structure Design of Our Fertilizer Rotary Granulator Machine?
The drive system of the rotary drum granulator mainly includes a motor, a reducer and a drive roller. The motor powers the rotation of the drum. The motor output is decelerated through the reduction gear, and the drum is driven to rotate through the reduction gear.
The drum is a pelletizing container. It is a cylindrical shape and its material is steel plate. It has a rubber plate attached to the inside to prevent highly viscous materials from sticking to the cylinder wall. The length and diameter of the drum depend on the quality requirements of the granulated material and the quality requirements of the granulated particles.
The gear teeth mainly include two parts, large gear guard and riding ring. The large gear guard is fixed on the rotary drum. Its main function is to maintain the position of the rotary drum. The riding ring is connected to the riding ring support, symmetrical on both sides of the drum. Its main function is to rotate the drum.
The drum granulator has a stable rectangular base. You should put it on a flat concrete floor. The machine base connects to the riding ring support on both sides to ensure the stable operation of the machine.
Innovative Design of Our Rotary Drum Granulator
Like most rotary drum granulators, our granulator also consists of a rotary drum, two riding rings and their bases, a large gear guard, the driving device and the machine base. It doesn’t sound like much, but these are the basic components of a rotary drum granulator. In fact, our rotary drum granulator has some special designs. It is these special designs that make our rotary drum granulators the choice of many fertilizer manufacturers. Whether it is an organic fertilizer production line or a compound fertilizer production line, you can use the drum granulator for fertilizer making. So what is the highlight of our rotary drum granulator?
Granulator Drum’s Hammering System
Given that the rotary drum granulator is wet granulation, the raw material after adding water will inevitably stick to the inner wall of the rotating drum easily. This not only wastes raw materials, but also corrodes the inner wall over time. So we set up round holes on the outside of the drum, and put hammers on these round holes. During fertilizer production, as the drum rotates, these hammers fall due to gravity and hit the round holes. The raw material sticking to the inner wall will peel off by vibration. The hammering system of the rotary drum granulator, on the one hand, can clean the inner wall like a cleaning device and keep the inside of the drum clean; On the other hand, it reduces the consumption of raw materials.
Stainless Steel Pressure Line
There is a rubber plate inside the rotary drum granulator to prevent it from sticking to the wall. And our rubber plate is covered with stainless steel pressure lines, which effectively fixes the rubber plate. Because it is stainless steel, it will not corrode. Overall, it makes the machine last longer.
One Molding Spiral Tube
The most important part of a rotary drum granulator is its drum. So what is the unique design of our rotary drum granulator? The answer lies in the one molding spiral tube used for our drums. The thickness of each place is the same, so there is no need to worry about cutting corners. When the drum is running at high speed, the quality of the drum is particularly important. The rotary drum material is Q235B boiler steel, which has high strength and not easily deformed characteristics.
Why are Drum Granulators Favored in Large Fertilizer Production Lines?
Large Output: the minimum output of the drum granulator is 1-3 t/h, and the maximum output can reach 15-30 t/h. It can fully meet the large-scale granulation production line. The output of a small drum granulator can equal the output of a large disc granulator. This is why many large-scale fertilizer production lines choose rotary drum granulators.
Enclosed Granulation: The whole process of rotary drum granulation is carried out in the drum, so there is no need to worry about the problem of powder sedimentation. It also means that in closed environments, raw materials are less prone to waste.
Low Energy Consumption: When choosing a granulator, energy consumption is also an important factor to consider. The motor and reducer of our drum granulator are from domestic brands with low energy consumption, which can help you save costs.
3 Hot-Selling Rotary Drum Granulator
NPK compound fertilizer rotary drum granulator
NPK fertilizers contain nutrients needed for healthy crop development. Its main ingredients are nitrogen, phosphorus and potassium. And named after the abbreviations for these substances. So how to granulate npk compound fertilizer? Drum granulator is the best machine for npk fertilizer production. First, you need to mix the raw powder containing NPK and other nutrients well. Second, you should add water or steam to provide bonding conditions. Finally, it is agglomerated into granules through the high-speed rotation of the drum granulator. Generally speaking, the production line for making npk fertilizer has a large processing capacity, and a high-yield drum granulator is the best choice.
Organic fertilizer rotary granulator machine
What do you do when you have a pile of animal waste? Maybe you have the idea of making organic fertilizers in your head. In addition to composting, granulation is an important step in making organic fertilizers. Whether it is cow manure, pig manure, sheep manure, chicken manure or horse manure, etc, you can granulate with a drum granulator. Due to its high output, many manure organic fertilizer production lines have chosen the drum granulator. We have different output drum granulators for you to choose, you can choose the appropriate type of drum granulator according to the scale of your production line.
High output rotary granulator machine
The production capacity of our rotary drum granulator is between 1-30t/h. Whether you are a small fertilizer producer or a large fertilizer producer, our drum granulator can meet your production needs. Compared with disc granulators, drum granulators have higher output. It is more suitable for the production of large-scale organic fertilizers, compound fertilizers and compound fertilizers.
