Extrusion granulatorIn a dispersion where solid and liquid coexist and are dominated by solid, the self adhesiveness of the dispersion is utilized to forcibly bond and enlarge the basic particles of the solid powder, forming a uniform and concentrated particle group with a certain shape and particle size.

The extrusion granulator mainly consists of mixing, granulation, drying, and auxiliary system equipment. After mixing, the powder enters the granulator to form a wet product with the required particle size, which is then dried to obtain a granular finished product, thus achieving the purpose of granulation. The extrusion granulator is divided into front discharge type and side discharge type. The diameter of the front discharge type granulation is generally selected between 1.5-12mm, and the diameter of the material type granulation is generally selected between 0.7-2.0mm. The particle shape is cylindrical, and the granulation rate is ≥ 95%.

Working principle of extrusion granulator: Dry materials aggregate into dense and hard large blocks under pressure, which is called the extrusion process; The process of crushing and sieving the cake into granules is called granulation. The function of compression is to squeeze out the air between particles, and to make the particle spacing close enough to generate attractive forces such as van der Waals forces, adsorption forces, crystal bridges, and embedded connections.Extrusion granulatorThe strength of extruded granules is mainly formed by the intermolecular forces between molecules.

The extrusion granulator is produced using a non drying ambient temperature process, with two specifications of one-time molding and output of 1-1.5 tons/hour and 1.5-3 tons/hour. The extrusion granulator has low investment, fast results, and good economic benefits. The complete equipment layout is compact, scientifically reasonable, and technologically advanced. The extrusion granulator is energy-saving and consumption reducing, with no discharge of three wastes, stable operation, reliable operation, easy maintenance, and wide adaptability to raw materials. It is suitable for granulation of various raw materials such as chemical and feed industries, and has a high product granulation rate.

The structure of the extrusion granulator integrates granulation, forming, and screening, making it have the characteristics of beautiful appearance, simple operation, and low energy consumption. The main components, such as the roller body, are refined from a new type of metal with anti-corrosion, wear-resistant, and impact resistant characteristics. Our company has also upgraded and renovated the frame part, and the bearing frame body is made of anti-corrosion casting as a whole component, which has better stability and can greatly improve the service life of rolling bearings and large shafts.Extrusion granulatorThe transmission part adopts a dual input transmission method, which not only improves the input power ratio, but also ensures the lubrication and sealing performance of the transmission gears. It has the characteristics of compact structure, good stability, good sealing, low noise, and easy operation and maintenance.
