SBM SCM Ultrafine Mill Helps 15,000 TPA Ferrite Production Project
Ferrites have become indispensable functional materials in modern electronics industry, communication technology, new energy and other fields due to their high resistivity, excellent dielectric properties and high-frequency magnetic permeability. However, the preparation process of ferrites is complex, with extremely high requirements for raw material fineness, uniformity and stability. The grinding technology in the production process directly affects the magnetic properties and reliability of the final product, making it one of the core links for technological breakthroughs in the industry.
Ferrite Preparation Process
The preparation process of permanent magnet ferrite materials is similar to the sintering process commonly used in the ceramic industry. The main process flow diagrams are as follows:
Annual Production of 15,000 Tons of Ferrite Grinding Production Line
As an innovative enterprise in the new material technology field, a Zhejiang-based company has long focused on R&D of new energy materials. Aiming at the high-end market, it has launched a high-performance ferrite powder R&D project with an initial annual output of 15,000 tons.
Different from traditional manufacturing enterprises, the client is a R&D-oriented institution, putting forward extremely strict requirements for indicators such as powder particle size uniformity, impurity content, and surface activity. As one of the few domestic enterprises capable of providing "R&D-level grinding solutions," SBM quickly formed an interdisciplinary team composed of material engineers, equipment designers, and process experts to provide the client with full-process support from raw material property analysis to test parameter debugging.
Upon project commissioning, the finished products not only met but exceeded customer expectations. Yet, SBM's service commitment went beyond delivery—we established comprehensive equipment health profiles, documenting operational data, maintenance records, and spare part replacements throughout the entire lifecycle to ensure worry-free production.
The inaugural collaboration with SBM proved resoundingly successful, earning high praise from the client: "Choosing SBM means more than acquiring top-tier grinding equipment—it’s forging a partnership with a truly reliable strategic ally."
Materials: Ferrite
Fineness: 400 mesh
Equipment: SCM Ultrafine Powder Grinding Mill
In response to the small-batch trial production needs during the R&D phase, SBM team abandoned the fixed processes of traditional large-scale production. Instead, they planned the plant layout and designed an efficient and low-carbon process flow scheme by integrating R&D requirements, expected output, and finished product precision.
Technical Challenges:
1. High Hardness and Wear Issues: The Mohs hardness of pre-sintered ferrite particles reaches level 6-7, causing the wear-resistant components of ordinary grinders to have a service life of less than 3 months.
2. Ultra-Fine and High-Precision Requirements: Achieving a fineness of 400 mesh requires high-precision classification, which traditional grinders struggle to balance with production capacity and energy consumption.
3. Particle Agglomeration Control: Ferrite has high surface energy, making it prone to agglomeration. Insufficient powder fluidity index affects the molding process.
Advantages of SCM Ultrafine Powder Grinding Mill
1. High Efficiency and Energy Saving: Under the same fineness and power conditions, the grinding efficiency of the SCM Ultrafine Powder Grinding Mill is 40% higher than that of jet mills and stirred mills, while energy consumption is reduced by 70%.
2. Precise Particle Size Control: Equipped with a new high-efficiency cage-type classifier and variable-frequency control, it allows convenient particle size adjustment with precise cutting diameter. The final fineness of the product can reach d97≤5μm in one pass.
3. Safe and Reliable Operation: The grinding chamber is free of rolling bearings and screws, eliminating issues such as bearing wear and equipment damage caused by loose screws.
Clean and Environmentally Friendly: Adopts a high-efficiency pulse dust collector, along with silencers and soundproof enclosures, reducing dust and noise pollution far below national standards.
Technological process of SCM ultrafine powder grinding mill
Ferrite materials enter the main machine through the feeding equipment and fall onto the material dispersing plate at the upper part of the rotating disc. Under the action of centrifugal force, the ferrite scatters toward the circumference and falls into the raceway of the grinding ring, where it is impacted, rolled and ground by the ring rollers. After processing through multiple layers of raceways, the material becomes powder. The high-pressure fan sucks external air into the machine and carries the ground ferrite powder into the classifier. The rotating impeller in the classifier causes coarse materials to fall back for re-grinding, while fine powders that meet the requirements are carried by the air flow into the cyclone powder collector and discharged through the unloading valve at the lower part as finished products. The air flow with a small amount of fine dust is purified by the pulse dust collector and then discharged through the fan and muffler.
SBM SCM ultrafine grinding mill has become the core equipment choice for this project due to its high production capacity, low energy consumption, and stable particle size control capabilities.
SBM has deepened its services by launching a "R&D escort" model, embedding a data collection module in the production line to record 32 parameters in real time, such as grinding pressure, classification speed, and feed volume. These parameters are linked with the client's material performance test data, while a series of operation training services are provided to lay a solid foundation for the client's subsequent independent production.
The implementation of this project not only helps clients break through the technical bottleneck of ultrafine grinding of ferrites but also represents a self-advancement for SBM. It has explored a collaborative innovation model of "R&D-oriented enterprises + high-end equipment manufacturers," providing a replicable template for the full chain of "R&D - pilot testing - mass production" in more new material fields.
In the future, SBM will continue to use technological innovation as its brush to write a new chapter of "Made in China with Intelligence" in the blueprint of new material R&D.
