Method for the production of mealy crude black powder which can be further processed

Abstract

A method for the production of mealy crude black powder from components consisting essentially of potassium nitrate, sulfur and carbon, all in particle form, comprises the steps of placing each component in a storage container, continuously withdrawing said components individually from said storage containers in the determined proportions, continuously feeding said separate components as particles into a circular oscillating cylindrical grinding zone consisting of at least two grinding zones rigidly interconnected and containing grinding elements, whereby said component particles are ground and mixed with each other with agglomeration of the individual component particles, and continuously withdrawing said mealy crude black powder. This mealy crude black powder is then compressed and granulated, followed optionally by further treatment such as polishing and graphitizing or grinding.
