A handling system for agglomerable materials has a hopper with four sidewalls, each sidewall having a slope differing from each of the other sidewalls by at least 5.degree.. The slopes are selected and the sidewalls have a length selected so that the outlet has a cross-sectional area not less than 50% of the cross-sectional area of the inlet. The handling system is well-suited for dispensing synthetic gypsum in the manufacture of Portland cement or wallboard.
[ What is claimed is:] [1.] A handling system for synthetic gypsum, comprising:four sidewalls with substantially planar inner surfaces, the inner surfaces having opposing side edges joined to each other at different angles to define a hopper with no two inner surfaces having the same angle with horizontal, the sidewalls terminating in an upper edge and an opposite lower edge;an inlet defined at the upper edge formed by the sidewalls;an outlet defined at the lower edge formed by the sidewalls, the cross-sectional area of the outlet being about 60% of the ...
