Introduce of rotary drum granulator micronutrient compound fertilizer granulation line

The drum granulation production line, also known as the rotary drum granulation production line, is widely used in the fertilizer industry for granulating various fertilizers. Here is a detailed introduction:

Process Flow

Batching: Fertilizer raw materials are proportioned according to the required formula. Common raw materials include urea, ammonium nitrate, ammonium chloride, ammonium sulfate, monoammonium phosphate, diammonium phosphate, single superphosphate, potassium chloride, potassium sulfate, etc.
Pretreatment and Crushing: The batched raw materials are pretreated and crushed to a certain fineness to meet the requirements of the granulation process.
Mixing: The crushed raw materials are evenly mixed in a mixer to ensure the uniformity of the components.
Granulation: The mixed materials are sent to a rotary drum granulator. In the granulator, water or steam is added to make the raw materials humid, and through the rotation of the drum, the materials are rolled and squeezed to form particles.
Drying: The granulated particles are sent to a dryer to remove the moisture in the particles, making them harder and easier to store.
Cooling: After drying, the particles are cooled to room temperature to improve their quality and stability.
Screening and Return: The cooled particles are screened. Qualified particles are sent to packaging, and unqualified particles are returned to the granulation process for reprocessing.
Packaging: The qualified particles are packaged to obtain the final product.
Characteristics
Large Production Capacity: The single - unit production capacity of the drum granulation production line is large, which can meet the production needs of different scales.
Closed Design: It has a closed - type design, which can reduce dust emissions and improve the production environment.
Energy - saving: By using steam to add water and increase the temperature during the granulation process, it can reduce the energy consumption of the subsequent dryer process to a certain extent.
Application Scope
Fertilizer Production: It is mainly used for the granulation of phosphorus compound fertilizers, such as monoammonium phosphate, diammonium phosphate, nitrogen - phosphorus - potassium compound fertilizers, heavy calcium superphosphate, etc. It is also used for ammonia granulation and the production of organic - inorganic compound fertilizers.
