Product Introduction:

At present, according to its granulation mechanism, the domestic granulation technology mainly has the following forms: pressure molding granulation method, stirred rolling granulation method, hot melt cooling granulation method, spray drum granulation method, spray fluidized bed granulation method.

Hot melt cooling granulation method: This granulation method is to heat the material to make it into a liquid state, and then the liquid through a special condensation way to cool it into a flake, hemispherical, strip, block of a granulation method. This granulation method requires the material to have the characteristics of low melting point and high solubility. The advantages of this granulation method are low failure rate and simple equipment. The process of making the material condense and crystallize into a specific shape by using the low melting point of the material (generally lower than 300℃) through a special condensation method. It mainly includes tower vibration jet granulation, spray granulation and fluidized bed cooling granulation.

Our company specializes in the design and manufacture of granulating extruder screw barrel with gradient type, mutation type, wave type, barrier type, double screen type, cone type, flow type, separation type, exhaust type, pin type, mixed type, double head, three head, multi first class. Suitable for various kinds of plastic regeneration, mixing, filling, strengthening, color mixing and other granulation. Design different screw according to the type of material processed.

Treatment process:

Vacuum nitriding, high frequency quenching, spray alloy layer, electroplating hard chromium layer.

Scope of application:

Granulator, plastic granulator;

Ordinary plastics, PA, PP, PC, PE, ABS, AS, PS, PVC, PMMA, LCP, PBT, PET, PPC, PPS, PAR, PO, magnetic powder, ceramic powder, aluminum and magnesium powder, iron powder, bakelite powder and other engineering plastics.
