Twin Screw Extrusion Granulator

Twin screw extrusion granulator

Summary：

In the solid based dispersion which coexists with liquid, the basic particles of solid powder are bonded and enlarged by means of forced methods (such as extrusion, gravity, centrifugal force, mechanical force, air flow impulse, etc.) by using the self-adhesive (or external adhesive) of dispersion, and form a certain shape and particle size uniform and concentrated particle group. The whole set of wet granulation plant is mainly composed of mixing (kneading), granulation, drying and auxiliary system equipment. After mixing (kneading), the powder enters the granulator to form the wet product with the required particle size. After drying, the granulated product is obtained, so as to realize the purpose of granulation.

Characteristic：

Set series twin screw extruder granulator, the diameter of front discharge granulator is generally 1.5-12mm, the shape of particles is cylindrical, and the granulation rate is more than 95%

Application：

It is widely used in rubber additives, food additives, plastic additives, catalysts, pesticides, dyes, pigments, daily chemical, pharmaceutical and other industries.

Advantage：

The granulation process of powdery materials is completed under wet conditions, which greatly improves the operation conditions of granulation and its subsequent processes (such as drying, packaging, etc.). Generally, it can reduce the dust emission by more than 90%. Through granulation, the agglomeration, bridging and pulsation of powder products can be avoided, and the secondary pollution caused by powder during use can be avoided, so that the physical properties of products can be greatly improved. In general, the stacking proportion of granulated products is greatly improved, so the space of transportation, storage and packaging can be saved. The product quality of multi-component compounding and mixing was analyzed.
