Description
PERLITE Glass beads have been the economical media of choice for more than 25 years.
PERLITE is low cost but perfectly suited for less difficult wet milling operations.
PERLITE beads are made of Silica Glass with Aluminum Oxide and specially formulated for optimum results in all bead mills and sand mills.
PERLITE beads undergo supplementary manufacturing processes to virtually eliminate voids, mal-formed beads, hollows, fused pieces and tails. These beads have a higher impact resistance and wear resistance than sand.
