Side volumetric feeder system

The lateral forced feeding device, which is designed and manufactured by our company with twin screw feeder extruders, is used for filling and strengthening inorganic materials such as glass fiber, talcum powder and calcium carbonate in the extrusion of twin screw feeder extruders. The quantitative feeder is fed to the side feeding device quantitatively, and then forced into the twin screw main engine through a special machine barrel and an equal clearance twin screw. If the addition material is added from the main feeding port in the conventional way, on the one hand, because the density of the material is different, especially when the powder is added, it will be easily stratified, which will cause the unevenness of the finished product. On the other hand, because the hardness of the added material is much higher, it will be solid, not plasticized, and it will be made from the solid conveying section of the barrel. The wear of the screw and barrel of the feeding section. However, if the side feeder is adopted, the filling material is added from the material melting section, the filling material is wrapped and mixed by the molten material, which avoids the wear of the screw and the cylinder, and reduces the energy waste caused by friction, effectively improves the production and production efficiency, and reduces the production cost.

According to the practical data obtained from the customer's production experience, the addition of calcium carbonate can reach 550Kg/h after using our company's side volumetric feeding system, and the addition of short fiber can reach 500 Kg/h, and the accuracy of filling content is improved. With the introduction of glass fiber as an example, the accuracy of the glass fiber content introduced by the long fiber is + 5%, and the side volumetric feeding system is introduced into the short cut glass fiber. The accuracy of the measured glass fiber content is up to 2%. It can be proved that the side feeding system not only greatly improves the output of the main engine, but also reduces the energy consumption, reduces the wear and tear, improves the life of the screw rod, and prolongs the replacement period of the screw assembly, thus improving the economic benefit.
