Roller extrusion pelleting machine is the main equipment of the compound fertilizer granulation. The equipment has an advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and the corresponding equipment facilities, and forming small production line, have a certain capacity of continuous mechanized production. Using the eugenics formula without drying, normal production, a rolling forming products, making the quality of the products conform to the requirements of the technical indicators of mixed fertilizer, was used in the production of various kinds of crops of high, medium and low concentration of energy saving of the special compound fertilizer and compound fertilizer industry upgrading products.

Working Principle:

Roller extrusion pelleting machine has a high speed rotating mechanical shearing force and the resulting air power, make the continuous implementation of the fine powder material in the machine mixing, granulating, spheroidizing, density and other process, so as to achieve the goal of the granulation. Actually the particle shape is spherical, the spherical degree is ≥0.7 , usually in the particle size of 0.3-3 mm, granulating rate is 90% or higher, the size of the particle diameter can be adjusted through the spindle speed and quantity of the material mixing appropriate, often mix amount is lower, the higher the speed, the smaller the particle, and vice versa.
