High Purity

The fragmentation of high purity solid materials is confronted with potential contamination issues. The risk of metal or plastic contamination from conventional crushing equipment is high, and difficult and expensive to fix afterwards. SELFRAG’s Rod Crusher crushes material without contacting it, making it the ideal solution to process your high-purity material.

More information on the advantages of SELFRAG systems in silicon production can be found in this guide.

    • • Increased production efficiency with automated crushing process
                • Precise target size fraction can be defined
                • Narrow product particle size distribution ensures material minimal losses to undersize
                • Round product shapes are suitable for continuous feeding processes
  • • Improved health and safety
    •          • Automated process reduces worker interaction
    •          • Innovative wet process produces zero dust

The Rod Crushers annual throughput depends on the selected particle size distribution during crushing: full production lines from crushing to bagging are available up to 15,000 metric tons per year.

The controllable and adjustable size fractions allow production of various size classes according to needs and market trends.

Smooth and rounded particles produced by the contactless crushing process show less surface contamination than comparable, mechanically crushed material. 

Less chemical etching is needed due to lower levels of surface contamination, providing significant cost savings.

Increased production efficiency due to the overall speed of the automated process.
