Learn how the roller press granulator equipment makes npk compound fertilizer materials( nitrogen, phosphorus and potassium powder) and powered chemical materials(iron, coal, lime, starch, mineral, gypsum, graphite, bentonite, etc.) into granules.


The extrusion granulation production line is widely used in the production of compound fertilizer granules, mainly used to produce spherical granules with a diameter of 1mm-5mm. The equipment has low investment, quick effect, low energy consumption, compact layout, scientific and reasonable, no waste removal, and stable operation. Wide adaptability of raw materials, can be used for granulation of various raw materials such as compound fertilizer, medicine, chemical industry, feed, etc., high granulation rate, can produce various concentrations, various types (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer etc.) compound fertilizer.

Finished Granules

Introducing the cutting-edge roller press granulator production line, delivering exceptional high yield and excellent granulation rate! With advanced technology, our roller press granulator production line ensures efficient and precise blending of raw materials, resulting in uniformly shaped particles. The roller press granulator, at the heart of our line, guarantees outstanding spherical granules with a remarkably high granulation rate.
You can choose granules with different shapes and size:

Main Equipments

All equipments for processing compound fertilizer:

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.
Disc feeder for offering the raw material to the granulator evenly.
Roller press granulator for making the fertilizer granules.
Rotary screener 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.
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.
