Twin Screw Extruder Degassing Side Feeder for Petrochemical Factory

Degassing Side Feeder is used to enhance feeding

1. Introduction:

In the feeding process of powder, fiber and other loose materials, because these materials contain a lot of air, it is easy to produce blockage when using the side feeder to feed the main machine, and reduce the feeding capacity. In order to enhance the feeding capacity, it is necessary to eliminate the gas contained in the material, gas-solid separation, reduce the obstruction of gas, so that the feeding is more smooth, so as to improve the feeding capacity, and promote the stable operation of the host machine.

2. Application:

Suitable for double screw mixing field to add all kinds of organic/inorganic fillers, reinforcing agent, such as mineral powder (calcium carbonate, talcum powder), wood powder, fiber, feather, thin sheet and other forms of loose materials.

4	Screw Section	2	pcs	Mixing and conveying the filler
5	Barrel Section	2	pcs	Carry the screw shaft and melt the material
6	Bracket	1	set	Supporting the Side Feeder
7	Electric control cabinet	1	set	Controlling the machine

4. Structure features:

Two-stage cylinder, block type conjugate double helix propulsion, cylinder can be equipped with cooling channel;The gas-solid separation section is connected with the vacuum system and the backblowing compression-shrinkable air system.The operation control system adopts PLC+ touch screen.

5. The design principle:

We use vacuum exhaust and filtration separation technology to complete the gas-solid separation in the process of spiraling the gas-containing loose material to the main engine, so as to reduce the obstruction of gas to the transportation and avoid the reverse flow of the material, so as to achieve the purpose of enhancing the feeding.

6. Usage:

The side feeder is connected to the main extruder with flange and the open barrel of main extruder should match the side feeder as request.

The specific model is determined by the main extruder model and actual use.
