Magnetic Separation for Silica Powder: A Long-Term Application Case

JINHONG has supplied a total of 200 magnetic separation units to an electronic-grade silica powder manufacturer. The earliest units have been in use for seven years, and the customer has continued purchasing equipment every year. This case describes that long-term supply relationship in high-purity silica powder production; the customer remains anonymous.

Magnetic separation for silica powder

For a silica powder producer evaluating an iron-removal system, the equipment must be considered together with the material and production conditions. Powder flow, moisture, feed rate, available installation space and cleaning arrangements are all part of the selection discussion.

Our experience supplying equipment for this application provides a practical starting point for reviewing another producer’s requirements. The appropriate configuration and expected separation performance still need to be established for that producer’s material and contamination.

Explore the JH-LX self-cleaning solution

The JH-LX self-cleaning magnetic separator for powder is one of JINHONG’s solutions for gravity-fed dry powder applications, including high-purity silica powder. It uses pneumatic automatic cleaning. Its configuration should be reviewed together with compressed-air supply, collection of discharged iron and dust, and access for inspection and maintenance.

What to provide for a similar application

To review a magnetic separator for your silica powder line, please send:

• Material name, particle-size distribution, bulk density and moisture.
• Normal and maximum throughput, and operating temperature.
• The type of iron contamination and any available particle-size or test information.
• Your required product specification and how it is measured.
• Inlet and outlet dimensions, available installation height and a process sketch.
• Available compressed air, dust collection and preferred cleaning arrangements.

The size of the silica powder and the size of the iron contamination are separate specifications. Providing both, where available, helps us review the application accurately.
