Abstract
Procedure and device for the manufacture of hollow spheres, particularly of concrete; according to the principle of centrifugal casting, by rotating a spherical container for the molding material, which rotates on at least two axes, characterized by the fact that pure concrete, concrete with plastic materials, is used as the molding material or polyester concrete; that the starting components of the molding material are introduced into the spherical container without being mixed in a previously calculated amount, for the body to be molded, these components being entirely mixed by the first and lowest speeds of all axes rotary, that the rotational speed of the spherical container is then increased along all its axes at an essentially spin speed, whereby the mixture of molding material is distributed uniformly on the inner wall of the spherical container.
