Ultra Centrifugal Mill FM200
Feed size:＜10mm
Final fineness:＜40μm
Speed:6000-20000rpm
The Ultra Centrifugal Mill FM200 is suitable for a broad spectrum of samples. Leveraging its highly efficient grinding technology and a comprehensive set of accessories, it can rapidly perform both dry and wet grinding. It utilizes a two-step grinding process involving a rotating knife and a ring screen system, allowing for the quick processing of soft, hard, brittle, and fibrous samples.
- Sample types: Soft, elastic, fibrous, water-containing, dry samples.
- Application fields: Agriculture, environmental analysis, electronics, RoHS testing, coal analysis, chemistry, plastics, medicine, feed analysis, grain analysis, dry plant analysis, and more.
Versatile Applications, Effective Sample Preparation:
- Environmental Conservation: Preparation of plant samples (roots, stems, leaves, etc.), C.H.N determination.
- Coal and Coatings: Sample preparation for ash content and thermal measurements.
- Analysis of Nitrogen and Protein Composition: Identification of nitrogen and protein composition in feed and food.
- Secondary Fuel and Waste: Determination of harmful substances in secondary fuel, waste, plastics, and electronic components.
Working Principle
The Ultra Centrifugal Mill achieves a two-stage crushing process using the rotor and ring sieves. Samples are introduced through a hopper designed to prevent splashing. The combination of high-speed centrifugal force and the rapid rotor movement generates a significant impact force, serving as pretreatment for the samples. Subsequently, the samples undergo shearing, extrusion, and rubbing between the rotor and ring sieves.
When the sample size becomes smaller than the aperture of the ring sieves, it is collected in a pan. This two-stage crushing approach ensures moderate and efficient grinding results. Thanks to the high crushing efficiency, samples spend a relatively short time in the grinding chamber, preventing alterations in sample properties.
