The disc granulator is one of the key equipment in organic fertilizer production lines, mainly used to process uniformly mixed organic fertilizer raw materials into spherical particles. The granulation process and characteristics are as follows:
Granulation process
Raw material pretreatment: Before entering the disc granulator, the raw materials need to undergo pre wetting, preheating and other treatments to reach the appropriate moisture content and temperature, in order to improve granulation efficiency and particle quality.
Entering the disc: The pre processed raw materials enter the disc from the top center of the disc granulator, and the disc tilts at a certain angle and rotates at a certain speed.
Granulation process: Under the rotation of the disc, the raw materials begin to roll into clusters and gradually form particles through their own gravity and centrifugal force. At the edge of the disc, particles are ejected due to centrifugal force and enter the subsequent processing stage.
Particle forming: During the rolling process, due to the viscosity of the raw material, the particles gradually increase until they reach the desired size and shape.
Granulation characteristics
High granulation efficiency: The continuous granulation method of the disc granulator can quickly and efficiently process raw materials into granules, improving production efficiency.
Particle uniformity: By precisely controlling the rotation speed, tilt angle, and humidity of the raw materials, particles of uniform size and shape can be produced, which is beneficial for the uniform application and storage of fertilizers.
Easy to operate: The disc granulator has a simple structure and is relatively easy to operate and maintain, making it suitable for large-scale production.
Strong adaptability: capable of handling various types of organic fertilizer raw materials, including powdered, granular, and partially fibrous raw materials, suitable for granulation needs with different raw material characteristics.
Low energy consumption: Compared with other granulation methods such as extrusion granulation, the disc granulator has lower energy consumption during the granulation process, which helps to reduce production costs.
Good particle strength: By adjusting the parameters during the granulation process, the hardness and compressive strength of the particles can be controlled, ensuring that they are not easily broken during transportation and use.
Easy to adjust particle size: By changing the tilt angle, rotation speed, and feed rate of the disc, the particle size can be flexibly adjusted to meet the needs of different fertilizer products.
The disc granulator plays an important role in organic fertilizer production lines. Its efficient granulation ability and adaptability to various raw materials can significantly improve production efficiency and product quality, making it one of the indispensable key equipment in organic fertilizer production lines.
