Construction site of drum granulation compound fertilizer

Construction site of drum granulation compound fertilizer

The construction site of drum granulation compound fertilizer is a place where raw materials such as nitrogen, phosphorus, and potassium are processed into granular compound fertilizer through drum granulation equipment. Here is the relevant introduction:
main equipment
Drum granulator: It is the core equipment that uses the rotation of the cylinder to roll, collide, and bond materials into balls inside the drum. The cylinder can be lined with soft rubber or polypropylene board and can automatically clean the material.

Blender: Used to thoroughly mix various powdered raw materials, binders, additives, etc., ensuring that the materials entering the granulator are uniform and consistent. Common types include disc mixers.

Drying machine: Drying the granulation material to remove moisture and achieve the specified moisture content standard.
Cooling machine: cools the dried material for subsequent screening and packaging.
Screening machine: Classify the cooled particles and screen out qualified particles. Unqualified large particles are crushed and returned to the granulator together with fine powder for re granulation.
process flow
Raw material preparation: Prepare various powdered raw materials (granular raw materials need to be crushed in advance), binders, additives, etc. according to the formula ratio.
Mixing and stirring: Pour the raw materials into the mixer and stir thoroughly, then evenly transport them to the drum granulator through a belt conveyor.
Granulation: The material is heated and humidified by steam in the drum granulator, rolled and bonded into balls under the rotation of the cylinder, and then flows out of the granulator.
Drying and cooling: The granulated material is sent by a belt conveyor to the dryer for drying, and then enters the cooling machine for cooling.
Screening and packaging: The cooled material is classified by a screening machine, and qualified particles are measured and packaged. Unqualified particles are returned to the granulator for further granulation.
Site layout
The construction site is usually located inside the factory building, with equipment arranged in an orderly manner according to the process flow, connected by belt conveyors, bucket elevators, etc., forming a continuous production line.
We will set up raw material storage areas, finished product storage areas, as well as necessary maintenance areas and operation control rooms to ensure efficient and safe production processes.
