Southern Devices, a division of Leviton Mfg. Co., Morganton, N.C. applies a ceramic glaze on some of the low-tension electrical porcelain products it produces.

Since many of the characteristics of a glaze are determined by grinding time and particle size distribution, engineers at Southern Devices conducted a comparison of ball milling and attrition.

Under normal production requirements, Southern Devices grinds 300 gal of glaze/day. The ball mill has a 150-gal capacity, which requires making two grinds/day. The attritor offers the capability of making one grind/day and, ...
