About Urea 46

Urea is a high-concentration nitrogen fertilizer with a nitrogen, phosphorus, and potassium ratio of 46-0-0. Usually, the nitrogen content of urea fertilizer is divided into different purity levels, and the common urea fertilizers are 46% and 52%. Urea fertilizer is suitable for fertilizing various agricultural crops. Nitrogen is one of the main nutrients required for plant growth. It has an important impact on the growth and development of plants and the formation of yield. When using urea 46%, it is necessary to apply fertilizer scientifically according to the needs of crop growth and soil fertility to avoid fertilizer waste and soil pollution caused by excessive fertilization.

Urea Fertilizer Granulation Production Process

Urea fertilizer granulator can efficiently process powdered or granular urea raw materials into spherical urea granules through extrusion, rotation, kneading, etc., which is beneficial to the absorption and utilization of crops during the fertilization process.

▶  Dry Granulation

Urea fertilizer can be used in the dry granulation process, and a double roller extrusion granulator is a commonly used dry granulation equipment. Urea has a low water content, which is conducive to the dry granulation process.The double roller extrusion granulator can obtain urea granules in one extrusion, and the finished urea granules do not need to be dried. The double roller extrusion granulator has the characteristics of high production capacity, uniform finished granules, low energy consumption, and a wide range of applications. It is widely used in the granulation production of powdered materials.

  Double Roller Extrusion Press Granulator for Sale  

The dry granulator is a granulator for preparing granular urea or other granulated products, among which the double roller extrusion granulator is one of the commonly used and hot-selling dry granulation machine. The double roller press granulator has the following characteristics and advantages:

• Double roller press structure: The double roller extrusion press granulator consists of two symmetrical rollers. By controlling the pressure and speed, the powdered raw materials are squeezed into granular flakes, and then the pellet granules are dispersed into granular fertilizers by the disintegration device. The finished granules have high uniformity.

• Adjustable pressure: The pressure of the double-roller extrusion press granulator machine is adjustable to meet the granulation needs of different raw materials, and can achieve high-efficiency granulation with a ball formation rate of up to 93%.

• Wide range of application: The double-roller extrusion granulator is suitable for granulation of various particles, including fertilizers, pesticides, granular food additives, graphite particles, cat litter particles, snow melting agents, desiccants, detergents, etc.

• Finished particles are strong: The particles prepared by the double-roller extrusion granulator have high density, and strong strength, are not easy to break, are more stable during transportation and use, and are not easy to agglomerate.

• High production efficiency: The double-roll extrusion granulator has high production efficiency, can realize continuous production and automated operation, improve production efficiency, and reduce labor intensity.

Based on the above characteristics, the double-roll press dry granulator is highly favored in the granular fertilizer and other granule preparation industries, and is a hot-selling dry granulation equipment. When choosing a dry granulator, you can consider the double-roll extrusion granulator as a reliable option.

▶  Wet Granulation

Urea 46% is a highly soluble fertilizer. Wet granulation can ensure that urea is fully dissolved under the action of water, which is conducive to the agglomeration and molding of particles. Wet granulation can more easily control the shape and size of particles, ensuring the uniformity and consistency of particles. At the same time, wet granulation can promote chemical reactions between materials in a wet environment, which helps to improve the density and firmness of particles.

  Hot sale rotary drum granulator  

The rotary drum granulator is a common and popular wet granulation machine, which is mostly used in the granulation production process of fertilizers, granular fertilizers, compound fertilizers, organic fertilizers, etc.

It mixes the raw materials and additives through the rotating drum, combined with the wet granulation process, and gradually forms fertilizer granular finished products through friction, extrusion, impact, and other forces.

The main features of the rotary drum granulator include:

• Efficient granulation: The rotary drum granulator is designed with a specific stirring device and granulation plate inside, which can effectively mix the raw materials and additives and form uniform particles.

• Easy to operate and maintain: The structure is simple, easy to operate, easy to maintain and clean.

• Controllable particle quality: The size, shape, and density of the particles can be controlled by adjusting the rotary drum granulator speed, slope, feed speed, and other parameters.

• Strong production capacity: Suitable for large-scale production, and the fertilizer granulator machine's production capacity can be adjusted according to demand.

• Wide range of applications: Suitable for granulation production of various raw materials and various wet granulation processes.

The rotary drum granulator is a practical wet granulation equipment that can help produce granular fertilizer products such as urea. It has a wide range of applications and has the advantages of high efficiency, easy operation, and controllable granule quality.
