Grinding beads
Since 1854 Sigmund Lindner has been producing technical glass beads for the grinding of pigments, minerals and raw materials as well as precision beads used in pharmaceutical, vial sealing, military or electronic applications .... Sigmund Lindner has established itself as one of the leaders in ceramic balls for applications requiring high performance in terms of fineness and grinding efficiency.
Description
The type of grinding balls to be used depends on the product to be ground (initial and final particle size), the type and characteristics of the grinder, the desired grinding efficiency and the budget.
Find detailed information in the section:
Glass grinding balls
• Smooth and homogeneous surface, low rate of air bubbles.
• High degree of roundness and elasticity.
• Narrow particle size distribution.
• Many sizes available.
