Hydraulically powered horizontal presses, developed by Lammot du Pont, a grandson of the founder, replaced early vertical screw presses driven by hand. Sorting and classifying the resultant powder cake by size took place in the graining mill, again with mechanical methods, originally with leather sieves and later using rotating classifiers called bolters. The moisture added to powder in the incorporating process was reduced to 1⁄2 of 1%. Originally this was done on dry tables or in dry houses. Later improvements combined drying with glazing. The rough edges of the powder grains were smoothed off in the glazing mill. In the pack house, workers gave the powder a final screening,...
