Double roller extrusion granulator – the key equipment for compound fertilizer granulation

Double-roller extrusion granulator, the shape and size of the ball socket on the roller skin can be customized according to user needs. Double-roller extrusion granulator has a wide range of choices. The ball pressure shapes include pillow-shaped, semi-circular granular, and rod-shaped. shape, pill shape, walnut shape, oblate spherical shape and square bar shape. At present, they all adopt the shape of oblate ball.
The double-roller extrusion granulator is produced using a non-drying and room-temperature process and is formed in one go. This equipment has low investment, quick results and good economic benefits. The complete set of equipment has a compact layout, scientific and reasonable layout, and advanced technology. Energy saving and consumption reduction, no three wastes discharged, stable operation, reliable operation and easy maintenance. The raw materials have wide adaptability and are suitable for granulating various raw materials such as compound fertilizers, medicines, chemicals, feeds, etc. The product granulation rate is high.
The double-roller extrusion granulator is the key equipment for compound fertilizer granulation. It has advanced technology, reasonable design, compact structure, novelty and practicality, and low energy consumption. It can be matched with corresponding equipment to form a small production line, which can form a certain continuous production capacity. , mechanized production, no need for drying, normal temperature production, the product is rolled and formed in one time, so that the product quality meets the technical index requirements of compound fertilizer. It is used for the production of high, medium and low concentration special compound fertilizers for various crops and the compound fertilizer industry Renewal products that save energy and reduce consumption.
Capsule filling particles, pigments, detergents, catalysts, strontium carbonate, fertilizers, white carbon black, inorganic salts, isochlorides, cyanuric acid, pesticides, oxides, etc., as well as industrial recycled dust materials: such as iron foundry dust, lead , zinc, aluminum dust, converter dust, filter dust, grinding and other dust. The material is forced to be compressed and molded by mechanical pressure without adding any wetting agent, and the product purity is guaranteed.
The extrusion granulation production process is short, has low energy consumption and large output. The dry powder is directly granulated without the need for subsequent drying processes, which is more conducive to the connection and transformation of existing production processes. The granules have high strength and the increase in stacking specific gravity is more significant than other granulation methods. It is especially suitable for occasions where the product accumulation proportion is increased. It has great operating flexibility and wide adaptability. The extrusion force can be adjusted through hydraulic pressure.
