ER-120S® Grinding Media Features

If your business is a current user of SEPR "ER" series of zirconium silicate grinding beads, Quackenbush can now meet your mill media needs.  We offer competitive pricing for ER-120A®, ER-120S®, and the latest product from SEPR/Saint Gobain, ERMIL®.  All three types of beads are electrofused zirconia that feature a very smooth surface for low mill and media wear.

One advantage of the production method is that a wide variety of diameters are available.  Indeed, the electrofusing process is the best method of producing very small diameter beads.  For larger diameter media needs, our QBZ-58A is the product of choice due to it's tight size tolerances and high spericity.

Sizes available are 0.1, 0.2, 0.3, 0.4, 0.6, 0.8, 1.0, 1.25, 1.6, and 2.0 mm diameters.
