What is the working principle of the rotary drum granulator

fertilizer granulator Aug 8, 2024

Drum granulator is a granulation equipment widely used in the fertilizer, chemical, food and other industries. Its working principle is based on the combination of physical and chemical processes, mainly completed through the following steps:

Raw material mixing and pretreatment:

Firstly, various raw materials (such as nitrogen, phosphorus, and potassium compounds in NPK fertilizers) are mixed in a certain proportion. The raw materials may need to be crushed, sieved, or pre dried to ensure their uniform dispersion during the granulation process.

Granulation process:

The raw materials enter the cylindrical granulation chamber of the rotary drum granulator, which is composed of a tilted and slowly rotating cylinder. The raw material forms a spiral motion under the action of the rotational force and centrifugal force of the cylinder.

In the granulation room, the raw materials are evenly sprayed with appropriate amount of water or binder through the spray system. The function of water or binder is to enhance the cohesion between particles and promote the aggregation of small particles into larger ones. This process is called “drum granulation” or “rotary granulation”.

Particle growth and solidification:

As the cylinder rotates, small particles gradually grow through rolling and collision. Moisture or binders allow the components in the raw materials to adhere at the contact points, forming a more stable structure.

During the granulation process, the size and shape of the particles can be controlled by adjusting the rotation speed of the cylinder, the water spray system, and the feeding rate of the raw materials. The longer the particles roll inside the cylinder, the larger the particle size will generally be.

Particle screening and post-processing:

After granulation is completed, the particles are passed through a sieve or screening device at the end of the cylinder to remove oversized or undersized particles, ensuring uniform particle size in the final product.

The particles may also need to be dried to remove excess moisture and prevent clumping during storage and transportation. In some cases, cooling, polishing, or coating treatment may also be necessary to improve the hardness and stability of the particles.

The working principle of a rotary drum granulator is to use the combination of physical motion (such as rotation and rolling) and chemical action (such as the addition of moisture or binders) to form uniform and stable particles of raw materials. This process can not only improve the efficiency of raw material utilization, but also customize the size, shape, and hardness of particles according to specific needs to meet the needs of different industries and applications.

How does the rotary drum granulator work in the fertilizer production line

fertilizer granulator Aug 8, 2024

Drum granulator is a device that utilizes physical and chemical principles to process powder or fine granular materials into larger and more uniform particles. Its working principle mainly includes the following steps:

Raw material preparation:

The raw materials are first sent to the granulator, which can be dry powder, wet powder, or pre treated materials. The initial state and composition of the raw materials will affect the parameter settings of the subsequent granulation process.

Entering the drum:

The raw materials enter the cylindrical granulation chamber of the rotary drum granulator through the feeding port. The granulation chamber is usually a tilted cylinder, which may be equipped with lifting plates, blades, or other structures inside to promote the rolling and mixing of materials.

Humidification and bonding:

In the granulation room, evenly spray appropriate amount of water or binder to the raw materials through the spray system. The addition of water or binder is crucial in the granulation process, as their function is to bond the particles in the raw material together and form larger particles. The amount of humidification and the type of binder need to be precisely controlled based on the characteristics of the raw materials and the properties of the target particles.

Rolling granulation:

As the granulation chamber rotates, the material rolls inside, and small particles aggregate into larger particles under the action of moisture or binder. The inclination angle and rotation speed of the cylinder can be adjusted to control the size and shape of the particles. By combining physical rolling and chemical bonding, the material gradually forms the required particles.

Particle screening:

After granulation is completed, the particles are discharged through the discharge port of the granulation chamber. These particles are usually subjected to a screening device, such as a vibrating screen or a rotary screen, to remove particles that are too small or too large, ensuring uniform particle size in the final product.

Post processing:

The screened particles may require further processing, such as drying, to remove excess moisture added during the granulation process and avoid clumping during storage or transportation. In some cases, cooling, polishing, or surface treatment may also be necessary to improve the physical properties of the particles.

The workflow of a rotary drum granulator is a continuous process, which can produce granular products with specific physical and chemical properties by precisely controlling parameters such as raw material mixing, humidification amount, cylinder rotation speed, and tilt angle. This process is not only applicable to industries such as fertilizers, chemicals, and food, but also has a wide range of applications in agriculture, pharmaceuticals, and environmental protection.

Application of Drum Granulator in NPK Fertilizer Production Line

fertilizer granulator Aug 8, 2024

The rotary drum granulator is widely used in the production line of NPK fertilizers (nitrogen phosphorus potassium compound fertilizers) and plays a key role in the production process of NPK fertilizers. The following are several important aspects of the application of rotary drum granulators in NPK fertilizer production lines:

Raw material mixing and granulation:

The rotary drum granulator can effectively mix raw materials through its rotating cylindrical structure. The raw materials for NPK fertilizers usually include different proportions of nitrogen, phosphorus, potassium, and possibly trace elements. After these raw materials are mixed evenly in a drum, stable particles are formed by adding an appropriate amount of water or binder. The mixing and granulation process of the rotary drum granulator can ensure the uniform distribution of various components in NPK fertilizer, which is crucial for improving the efficiency of fertilizer use and crop absorption.

Control particle size and shape:

The rotary drum granulator can precisely control the size and shape of particles by adjusting its rotation speed and the parameters of the water spray system. This is very important for NPK fertilizers, as different crops and planting environments may require different specifications of granular fertilizers. For example, larger particles may be suitable for field crops, while smaller particles may be more suitable for fine planting or greenhouse environments.

Improve the stability of particles:

The components in NPK fertilizers, especially nitrogen and potassium, are prone to volatilization or decomposition. The rotary drum granulator can improve the stability of particles, reduce the loss of fertilizer components, extend storage time, and improve transportation safety through physical and chemical reactions during the granulation process.

Improve production efficiency:

The continuous operation mode and high processing capacity of the rotary drum granulator greatly improve the production efficiency of NPK fertilizers. For large fertilizer production enterprises, this can significantly increase production capacity and meet market demand.

Reduce energy consumption:

Although the operation of the rotary drum granulator requires a certain amount of power, compared to other granulation methods such as high-pressure extrusion granulation, its overall energy consumption is relatively low. This is because the rotary drum granulator utilizes the physical properties and chemical forces of the material itself, reducing the dependence on additional energy.

Strong adaptability:

The rotary drum granulator can process raw materials with different humidity and viscosity levels, which is a huge advantage for NPK fertilizer production, as the properties of fertilizer raw materials may vary depending on the season, source, and processing method. The flexibility and adaptability of the rotary drum granulator ensure the stable operation of the production line and the consistency of product quality.

In summary, the application of rotary drum granulators in NPK fertilizer production lines can not only improve the uniformity of fertilizer components and the stability of particles, but also bring significant economic benefits to fertilizer manufacturers by optimizing production efficiency and reducing energy consumption. At the same time, its adaptability to raw material characteristics and controllability of particle size and shape enable NPK fertilizers to better meet different agricultural needs and improve crop yield and quality.

Process and Technology of Processing Fertilizer on Straw Organic Fertilizer Production Line

fertilizer granulator Aug 8, 2024

 Straw is one of the raw materials in the production of organic fertilizer, which is different from the manufacturing of NPK fertilizer and the treatment of livestock manure. There are special requirements and characteristics when straw is treated by organic fertilizer manufacturing process, which needs composting processing.

Production technology of organic fertilizer for processing straw
1. Traditional straw composting

The traditional straw composting technology has the advantages of long fermentation time, poor fermentation effect and simple equipment, which is suitable for small-scale application. The method of straw fermentation is as follows: firstly, the straw is crushed with a pulverizer, but not excessively crushed, and the factors such as moisture, carbon nitrogen ratio and pH value are adjusted. The optimum ratio of carbon to nitrogen is 25:1. Therefore, adjusting the ratio of carbon and nitrogen in composting materials is an effective measure to accelerate the maturity and improve the humus coefficient.

Generally, the preparation methods of fermentation compost include adding phosphate fertilizer, adding lime, adding manure and urine, etc. Straw should be soaked with enough water to make the moisture content of straw reach 60% – 70%, which is the key to success or failure of composting. The compost piles without decomposition agent are usually stored for about 40 days in summer, and the temperature in the compost can rise to 50 ~ 60. After the high temperature stage, the compost can be dumped inside and outside. The standard of rotten is: black, rotten and smelly, that is, straw turns brown or black brown. When wet, it is soft and elastic, and when dry, it is brittle and easy to be broken.

2. New-type straw organic fertilizer manufacturing process

Use large-scale, high-efficiency organic fertilizer fermentation equipment and biochemical technology to accelerate crop straw rot. That is, the method of mixing with fast decomposing agent and using compost turning machine to increase the temperature and speed of compost and shorten the period of compost. Generally, the straw is mixed with livestock manure (or urea) to meet the nitrogen required for microbial fermentation. Use a complete set of organic fertilizer turning machine for trough turning and throwing fermentation to improve fermentation efficiency, shorten fermentation cycle, and increase production capacity.
