After the powder is mixed, it enters the granulator to form a wet product with the desired particle size, and is dried to obtain a granular product, so as to achieve the purpose of granulation.
Overview:
In a dispersion where solids and liquids coexist and are dominated by solids, the self-adhesive (or external cohesiveness) of the dispersion is used to force the solids (such as extrusion, gravity, centrifugal force, mechanical force, airflow impulse, etc.) The basic particles of the powder are bonded and enlarged with each other, and form a uniform and concentrated particle group with a certain shape and particle size. The complete set of wet granulation equipment is mainly composed of mixing (kneading), granulation, drying and its auxiliary system equipment. After the powder is mixed (kneaded), it enters the granulator to form a wet product with the desired particle size, and is dried to obtain a granular product, so as to achieve the purpose of granulation.
Features:
The twin-screw extrusion granulator is divided into front discharge type and side discharge type. The diameter of the front discharge type is generally selected between 1.5-12mm, and the diameter of the side discharge type is generally selected between 0.7-2.0mm. , the particle shape is cylindrical, and the granulation rate is ≥95%.
