Wholesale Npk Granulator Machine - Double Screw Extruding Granulator – YiZheng

Double-Screw Extrusion granulation machine is a new granulation technology different from traditional granulation, which can be widely used in feed, fertilizer and other industries. Granulation is an important process especially for dry powder granulation. It not only determines the mass of granular fertilizer, but also relates to the quality and cost of fertilizer product.

This pelletizing function of Twin Screw Extrusion Fertilizer Granulator Machine is significantly enhanced by the special flowing mechanical condition and structure inside of the extruding zone. First of all, with the reverse rolling of the double screw, the materials in the extrusion area with repetitive high-speed strong rubbing and frequent shearing to increase the probability of mutual combining between the molecules of the materials. Second, the materials intense colliding and rubbing in extrusion area, make the extrusion pressure rising and keep stable in high pressure state. The temperature of extrusion area high pressure section can rise to above 75 ℃ rapidly. On the one hand, materials pressure and temperature are fully meet the granulating conditions. On the other hand, the strong homogeneous effect changed the molecular structure of materials, so that greatly improve the quality and strength of granules by the heat transferring and high-pressure extruding to get the higher quality fertilizer products.

(1) Reliable performance and high granulating rate, good granule strength and high bulk density

(2) Wide adaptability to raw materials.

(3) No destructive effect on material composition with low operating temperature.

(4) The granulation is finished by pressure, there’s no need any binder, it could promise the purity of product.

(5) The granulator has compact structure, easy for maintenance and repair

(6) Main driving parts are made of high quality alloy material, stainless steel, titanium, chromium etc., which are abrasion-proof, corrosion-proof, high temperature-proof, and have long service life.
