Notes: above parameters are typical test results, actual products are a little different.

Attention: when the whole ball mill is renewed by new ceramic ball milling of glaze, it should run free 2 hours with water and then spill the water and put glaze ball milling. Doing like this can eliminate the bad affection of impurity inside the ball mill and uneven ceramic ball surface to the glaze.
