Abstract
Improvements in EL type pulverizers provide for longer wear life and reduced incidences of parts failures include: deep-dish contour grinding rings, tight tolerance ball tracks, heavy-duty top grinding ring flukes, larger diameter grinding balls, and an improved all-metal, integral snubber design for limiting the horizontal movement of the top grinding ring in order to increase the useful life of the pulverizer elements.
