Screw extrusion granulator
Ⅰ, the working principle
SE series screw extruder granulator is divided into single screw (SES) and twin screw (SET) type, extrusion forms have front discharge and side discharge two kinds.
After mixing, kneading and wet material or low softening point (generally refers to less than 50℃) material under the screw conveying, extrusion, extrusion from the head opening template, and then drying or cooling to obtain granular finished products, so as to achieve the purpose of changing the powdery product into a uniform granular product.
The particle shape is cylindrical, and the particle diameter of the finished product can be adjusted and controlled by the template opening aperture: the side discharge is 0.7-2.0mm, the front discharge is 1.5-12mm, and the granulation rate is ≥95%.
Ⅱ. Scope of application
Suitable for rubber additives, food additives, plastic additives, catalysts, pesticides, dyes, pigments, daily chemical, pharmaceutical and other industries need to granulation products.
Ⅲ, the main advantages
1. Because the powdery material completes the granulation process in the wet state, the operating conditions of the granulation and subsequent processes (such as drying, packaging, etc.) are good. Generally, it can reduce the dust flying on site by more than 90%.
2. Through granulation, the phenomenon of caking, bridging and pulsation that affect the use of powder products can be reduced, and the secondary pollution caused by powder in the use process can be reduced, so that the physical properties of the product can be greatly improved.
3. Under normal circumstances, the accumulation proportion of granulated products has increased greatly, so it can save transportation, storage and packaging space.
4. For multi-component composite and mixed products, granulation can reduce segregation of each component, thereby compounding product quality.
