Drum Granulator
The optimal solution for large-scale continuous granulation

Drum Granulator Overview
Rotary drum granulator is a kind of mechanical equipment widely used in granule production. Its main body is a rotating drum, when working, the prepared material is fed into the drum. Under the continuous rotation of the drum, the materials are rolled and agglomerated with the help of their own viscosity or the added binder, and gradually form granules.

Features and Advantages of Drum Granulator
Features and Advantages
Continuous production
The rotary drum granulator enables continuous tumbling and granulation of materials in the drum, allowing uninterrupted production of granules as long as a continuous supply of raw materials is ensured.
Stable granule moulding
By reasonably setting the roll speed, tilt angle and other parameters, it can ensure the stable growth of particles in the process of rolling agglomeration, and maintain a relatively stable granulation effect.
Wide range of application
Extremely adaptable to materials, can handle many types of materials. Whether it is powder, small particles, or materials with a certain viscosity or humidity are suitable.
Simple structure, durable
Its structure is simple in design, mainly composed of roller, transmission device, support structure and so on. There are no complicated wearing parts, and the key components are durable.
Flexible adjustment
According to different material characteristics and product requirements, it is convenient to adjust parameters such as drum speed, feeding speed, binder dosage and so on.
Can be automated
Equipped with an automated control system, the speed of the drum, the feed volume and other relevant parameters can be precisely controlled.

Working Principle of Drum Granulator
Working Principle
When the drum granulator is working, the main motor drives the belt and pulley, which are then transmitted to the driving shaft through the reducer. The gear on the shaft meshes with the large gear ring of the machine body to rotate the drum. The material enters from the feed end and moves along the axial direction while rotating with the drum due to gravity, friction and the action of the lifting plate. Steam or water is sprayed into the drum to make the fine particles adhere to each other and agglomerate into granules, which are then discharged from the discharge port.
Drum Granulator Application Scenarios
Application Scenarios
Compound Fertiliser Production
In compound fertiliser production, it can mix many kinds of nutrient raw materials such as nitrogen, phosphorus, potassium and binder in proportion. Under the rotation of the drum, the materials are gradually agglomerated into granules.
Organic Fertiliser Production
The production of organic fertiliser starts with the processing of organic materials such as animal manure and crop residues, which are then placed in a drum. Granules are formed by rolling and adding the appropriate binder.
Potassium sulphate granulation
During the production of potassium sulphate, the materials are bonded to each other during the rotation of the drum. The rotary drum granulator processes the powdered potassium sulphate into granules.
Ammonium chloride granulation
Ammonium chloride after industrial production is mostly in powder form and can be granulated using a rotary drum granulator. In the rotary drum, ammonium chloride powder is granulated under the action of a binder.
Microbiological Fertiliser Granulation
In the production of microbial fertilisers, a drum granulator allows the mixing of a bacteriological agent containing beneficial microorganisms with a carrier material to be granulated during the rolling of the drum.
Water treatment agent granulation
In the production of water treatment chemicals, rotary drum granulators can granulate powdered flocculants, disinfectants and other water treatment chemicals into granules that are easier to dissolve and disperse when used.
Drum Granulator Buying Guide
Buying Guide
Clarify the production scale
Select the rotary drum granulator according to your production scale. Consider the expected output to avoid under or over capacity.
Focus on pelletising quality
Check the equipment’s drum design, speed stability, etc. Ensure that the rotary drum granulator you purchase produces uniformly sized pellets.
Material adaptability
A rotary drum granulator with strong adaptability to materials should be selected. It should be able to handle a variety of materials with different composition, particle size and humidity.
Granule screening mechanism
Understand the design of the screening mechanism inside the equipment, such as the precision of the screen aperture, screening efficiency, whether it is easy to clog.
Equipment material quality
The drum should be made of high-strength, wear-resistant, corrosion-resistant alloy steel, and other key components should also be made of high-quality materials.
Functions of the control system
The control system can realise automatic adjustment of drum speed, feeding quantity, and also automatic screening according to the granule size.
Frequently Asked Questions.
Our drum pelletising machine is of high pelletising quality. The scientific design of the drum can make the granules uniform in size, regular in shape and suitable in firmness. There is strict quality control in the production process to ensure that each pellet meets the high standard to meet your needs.
The drum is made of high quality alloy steel, which is wear-resistant and corrosion-resistant. Other key components also use high-strength materials to ensure that the equipment as a whole is sturdy and durable.
High-quality materials and advanced manufacturing process ensure stable operation for a long time. The rollers and other key components have been strictly tested and debugged for quality.
We have a perfect spare parts supply system, and we have sufficient stocks of common drums, screens and other wear parts.
The noise is reduced by optimising the structural design and transmission system. Normal operation will not cause obvious interference to the operator, can provide you with a relatively quiet working environment.
