Technological Evolution and Application Practice of Soft Ferrite Mixing and Granulating Machines

Soft ferrites (such as manganese-zinc and nickel-zinc ferrites) are core materials for electronic components, and their performance is highly dependent on the uniformity of raw material mixing and granulation. As a key piece of equipment in the manufacturing process, mixing and granulating machines have significantly improved the magnetic permeability, loss control, and temperature stability of soft magnetic materials through technological innovation in recent years.

Soft Ferrite Granulating Machine Equipment

High Mixing Uniformity Requirements: Soft ferrites require a uniform blend of the main components (iron oxide, manganese, and zinc) with trace additives (such as SnO₂ and Co₃O₄). Failure to do so will result in uneven grain size after sintering and increased fluctuations in magnetic permeability.

The granulation process impacts final performance: The density, shape, and size distribution of the particles directly affect the molded density and sintering shrinkage. Traditional mechanical crushing methods are prone to dust generation, while extrusion granulation can damage the additive coating.

Principle of the Inclined High-intensive Mixing and Granulating Machine for Magnetic Materials

Principle:

Utilizing an inclined cylinder and high-speed, three-dimensional impellers, this machine achieves integrated mixing and granulation through the synergy of centrifugal force and friction.

Advantages of using a granulator for magnetic material preparation:

Improved mixing uniformity: Multi-dimensional material flow, additive dispersion error <3%, and elimination of clumping.

High granulation efficiency: Single-pass processing time is reduced by 40%, and granule sphericity reaches 90%, improving subsequent compaction density.

Applications: Granulation of ferrite pre-sintered materials and binder mixing for rare earth permanent magnets (such as NdFeB).
