Learn how the drum granulator equipment makes organic materials( such as poultry manure, chicken manure, cow manure, farm waste, sawdust, straw, city sludge, medicine residue, etc.) and npk compound powder( such as nitrogen, phosphorus, potassium, ammonium sulfate, calcium nitrate, ammonium chloride, motassium sulfate, magnesium sulfate, etc.) into granules.


The compound fertilizer production line with drum granulator is widely used in the granulation of various raw materials such as compound fertilizer, mineral, chemical industry and so on. Drum granulating machine is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizer. The main working method is wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after the humidity is adjusted in the cylinder. Under certain liquid phase conditions, the rotation of the cylinder makes the material particles Generate extrusion force to agglomerate into balls.

Finished Granules

Our drum granulator is the perfect solution for converting organic waste, such as chicken manure, cow manure, and other animal waste, or NPK compound fertilizer into high quality fertilizer granules. With our advanced drum granulator production line and top-notch fertilizer equipment, we guarantee exceptional results. NPK compound powder after granulating:

Main Equipments

Equipments for rotary drum granulator fertilizer production line:

Automatic batching system The automatic batching system includes silos and outriggers, safety nets, weighing belts, and automatic control cabinets. The main function is to reduce work intensity, increase output, achieve continuous production, and improve formula accuracy.
Crushing machine Mainly used for the crushing of raw materials to meet the requirements of granulation
Mixing machine It is used for mixing and stirring materials, adjusting the moisture content of materials, adding trace elements to meet the needs of granulation.
Rotary drum granulator for making the fertilizer granules.
Rotary dryer It is mainly used for drying after granulation, so that the granules can quickly reduce the moisture at high temperature, which is convenient for storage and achieves continuous and uninterrupted production.
Cooling machine It is mainly used to cool down and remove moisture after drying, so that the material can quickly reach normal temperature, meet the storage requirements, and realize continuous and uninterrupted production.
Screener machine Wear-resistant steel mesh. It is mainly used for the separation of finished products and returned materials, and can also realize the classification of finished products, so that the finished products can be evenly classified.
Coating machine It is mainly used for dusting powder or liquid coating of granules, which can prevent caking and improve brightness. It is also used in various multi-functional bacterial fertilizers.
Package machine It is mainly composed of main machine, machine column, sewing machine head and conveyor belt. Different specifications can be packaged to improve work efficiency and reduce operating costs.
