Material introduction

As a high-performance industrial raw material, metal silica sand plays an irreplaceable role in many fields with its unique physical and chemical properties. This article will deeply explore the characteristics,

 application fields and screening technology of metal silica sand powder, especially the application of circular swing screen and square swing screen in its screening process.

Characteristics of Metal Silica Sand Powder

Metal Silica Sand Powder is a fine powder of silicon powder with high purity, high melting point, good heat resistance, high resistivity and high antioxidant effect. Its purity can usually reach more than

 99.9%, ensuring high performance in different application fields. In addition, Metal Silica Sand Powder also has good electrical conductivity and chemical activity, and is easy to mix and disperse with other

 substances. These characteristics further broaden its application range.

Application areas

Refractory materials and powder metallurgy industry

Organic silicon chemical industry

High-tech field

Metallurgical casting industry

New ceramic alloy

Mesh number and screening technology

The mesh number of metal silica sand powder is an important indicator of its particle size. Common mesh numbers range from 200 mesh to 325 mesh. Screening is a key step to ensure that the metal

 silica sand powder reaches the required particle size distribution. Circular swing screen and square swing screen are two commonly used screening equipment.

Circular Swing Screen

Working Principle: The circular swing screen simulates the effective principle of manual screening and achieves screening through nonlinear inertial vibration. Its basic rotary motion is similar to manual 

screening, and the eccentricity and drive speed can be adjusted to meet the screening needs of different materials.

Advantages: Circular swing screen: suitable for screening of coarse particles and powders with a mesh size of 500 or above, with high screening efficiency and low noise. It can be separated in 

1-6 levels. In addition, it uses high-efficiency screen cleaning device systems such as silicone rubber balls and ultrasonic waves to prevent clogging of the screen holes. The fully enclosed structure 

and good sealing effect effectively avoid dust pollution of materials.

Square gyratory sifter

Although the Square gyratory sifter is different from the circular swing screen in structure and working principle, it also has efficient and accurate screening performance. The design of the Square gyratory

 sifter is usually more compact and suitable for use in occasions with limited space.

Advantages: Square gyratory sifter: suitable for screening fine particles with a coarseness of 120 mesh, with a large processing capacity and suitable for mass production. Suitable for screening 2-10 

materials of different sizes; the Square gyratory sifter also has the advantages of high screening efficiency and high screening accuracy, and is easy to maintain and operate.

Conclusion

Silica sand powder plays an important role in many fields such as refractory materials, silicone chemicals, high technology and metallurgical casting due to its unique physical and chemical properties. In

 order to ensure that the silica sand powder reaches the required particle size distribution, high-efficiency screening equipment such as circular swing screen and square gyratory sifter are widely used.

 These screening equipment not only improves the screening efficiency and accuracy, but also effectively avoids the dust pollution of materials, providing a strong guarantee for the production and

 application of silica sand powder.
