SiLiBeads® ...better grinding

Grinding media in all its variety is our expertise. We have been producing high-quality glass beads and ceramic beads for more than 160 years.

Our quality management to DIN ISO 9001 has been approved for years.

Quality and Know-how

Each production batch runs through a detailed quality check for diameter, sphericity, wear behaviour, inner structure and specific weight. We have established ourselves as specialists with our great accumulated experience and know-how in the field of grinding technology.

Besides the manufacture and distribution of grinding media, we also deal intensively with wet grinding technology.

We even work with attritor mills/pearl mills in our ceramic bead production and seminars, and can therefore offer our customers practical advice and optimize customers’ production processes by suitable measures.


In addition, we offer reprocessing and follow-up work for used grinding media. Our customers obtain cost-cuttings in beads consumption through this.

We stand for high quality of our products and for an effective use of our grinding media in order to obtain the highest customer benefit and provide customers with the best value.
