Gas protection vibrating screen
Gas protection vibrating screen is a high-precision fine powder screening machine with low noise and high efficiency. In order to process some materials with special properties, a gas protection device is added to process powder materials in a sealed environment without air isolation. Inert gas can be filled according to material properties.
1. Flange design at the feeding port, connected with the upper machine, automatic screening;
2. Install inert gas protection system to avoid deterioration of active materials;
3. The fully sealed screen machine avoids material exposure to air while reducing dust and waste;
4. The ultrasonic system is installed to realize ultrafine powder screening and automatic net cleaning.
The gas protection vibrating screen is equipped with a gas protection device. The part in contact with the material is made of 304 material. The vertical vibration motor is used as the excitation source, which can generate three-dimensional movements of horizontal, vertical and inclined. When the movement track is transmitted to the screen surface, it is larger than the screen hole The material with the largest size remains on the screen surface and is discharged from the coarse material discharge port, and the material smaller than the size of the sieve hole falls into the lower layer.
Gas protection vibrating screen is extremely suitable for the screening of fine, sensitive and reactive powder materials, and can also be used for the screening of some granular materials. It is widely used in metal powder, alloy powder, stainless steel powder, aluminum powder, silicon powder, graphite powder, tungsten powder. Screening of new materials such as powder and 3D printing materials.

At this stage, metal 3D printing has completed the development of large-scale equipment, and many printing service providers have begun to deploy large-scale equipment in batches. While using high-capacity milling equipment, stable and efficient classification of the produced powder is also required.
However, 3D printing powders are light, fine and some have special properties, which puts forward higher requirements for the use of screening equipment.
The screen surface of common screening equipment is a metal wire woven screen, which can distinguish powders of different particle sizes through its fixed aperture. However, the static powder is easy to get stuck in the screen holes. The ultrasonic device of the Gas protection vibrating screen can provide the function of cleaning the screen and solve the problem of blocking the screen.
3D printing powder needs to use airflow classification, and for more active metals such as titanium alloys and aluminum alloys, it is necessary to use inert gas circulating airflow to prevent their properties from changing, so Gas protection vibrating screen is an excellent choice.
