Twin screw granulator can be applied to various material processing

The twin-screw granulator is the main solid dispersion in the coexistence of solid powder and liquid, using the self-adhesive (or binder) of the dispersion, by forced means (such as extrusion, gravity, centrifugal force and mechanical force, airflow impulse etc.) to make the basic particles of the solid powder binder to enhance each other. And form a certain shape and uniform particle size, the concentration of particles. Wet granulation equipment is mainly composed of mixing, kneading, granulating, drying equipment and its auxiliary systems. After the powder is mixed and kneaded, the moisture of the product forms the desired particle size in the granulator, and the dry granule product is achieved, so as to achieve the purpose of granulation. Set type twin screw extrusion granulator point discharge type and end discharge type before discharge type, before discharge type granulation 1.5 to 12 mm in diameter, diameter between 0.7 - 2.0 and side discharge type granulation granule shape is cylindrical, granulated rate of 95% or higher.

To make masterbatches, it is often necessary to change the color, if the product needs to be changed, open the open processing area for a few minutes, and also by observing the melt in the screw profile mixing process. Now the common twin-screw extruder is changing its color, and it needs to use a large number of cleaning machines to clean the feeder, which is time-consuming, inefficient and wastes raw materials. Split casing twin screw extruders can solve this problem, change color, turn on the machine quickly in just a few minutes, and manually clean it so that it can use less or clean material and save costs.

After the twin-screw extruder is used for a period of time, the extruder needs a comprehensive inspection to check the tightness of all bolts. If there is suddenly no electricity in production, the main drive and heating stop, when the power supply is restored, the cylinder section must be heated to a temperature and kept warm for a period of time before starting the extruder. The twin-screw extruder has good feeding characteristics and is suitable for powder processing. Compared with the single-screw extruder, it has the characteristics of exhausting, reaction and self-cleaning functions, and poor thermal stability of plastic processing. It shows its superiority when mixing. . PVC Granulator
