Equipment process and granulation characteristics of organic fertilizer roller extrusion granulator


The organic fertilizer roller squeezing granulator uses dry extrusion technology to compress powdered materials with a moisture content of less than 20% into flakes, which are then crushed, granulated, and screened to transform the block like materials into granular materials that meet the requirements for use. Dry rolling granulation mainly relies on external pressure to force the material to be compressed into pieces through the gap between two relatively rotating rollers; During the rolling process, the actual density of the material can increase by 1.5-3 times, thereby achieving a certain strength requirement.

For the roller extrusion granulator equipment, the shape and size of the ball socket on the roller skin can be selected according to the user's needs, with a wide range of ball pressure shapes, including pillow shaped, semi-circular particle shaped, rod shaped, pill shaped, walnut shaped, flat ball shaped, and square bar shaped.

The roller squeezing granulator equipment is a key equipment for compound fertilizer granulation, with advanced technology, reasonable design, compact structure, novel and practical, low energy consumption, and matching with corresponding equipment to form a small production line, which can form a certain capacity of continuous and mechanized production.

The roller squeezing granulator equipment is a relatively new dry granulation process for producing composite fertilizers. Roller extrusion granulation has long been used in the field of fertilizers for granulation, and the granular form required for blending fertilizers (BB fertilizers) is mostly produced by extrusion method. Wide adaptability of raw materials, suitable for granulation of various raw materials such as compound fertilizers, pharmaceuticals, chemicals, feed, etc. The product has a high granulation rate and can produce various concentrations and types of compound fertilizers (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetized fertilizers, etc.), especially rare earth, potassium fertilizers, and carbon ammonium series compound fertilizers, filling the domestic gap and leading the domestic level.
