POWDER ROASTER AND ITS REFRACTORY BLOCK

摘要

FIELD: powder roasters. SUBSTANCE: roaster has directly fired kiln whose inner circular wall (at least part of this wall) is provided with many projections which have such form that powder will not rise considerably during operation kiln. According to preferable version, projections are made in the form of triangular prisms located inside kiln in such a way that they should pass through powder like plough. It is preferably that upper face of prism is made in the form of isosceles triangle whose equal angles are more than angle of repose of powder. Refractory block has at least one prismatic projection located on one side of main body. EFFECT: enhanced efficiency.
