Apparatus for manufacturing silica powder with spherical grains
TLDR
A rotary member is rotated at high speed by a drive shaft having its axis coincident with the axis of the cylinder as mentioned in this paper, which includes at least one paddle vertically aligned with the entry chute.Abstract:
A device for producing spherical silica grains includes a cylinder having its axis inclined to the horizontal and an inside wall made from a material that is significantly softer than silica. The cylinder has an entry chute for non-spherical silica grains and an exit chute for spherical cylinder grains. A rotary member is rotated at high speed by a drive shaft having its axis coincident with the axis of the cylinder. The rotary member includes at least one paddle vertically aligned with the entry chute so that silica grains entering via the entry chute are thrown by the paddle against the inside wall of the cylinder and follow a path most of which is against the wall before leaving via the exit chute.read more

Method and apparatus for continually forming spherical objects
TL;DR: The method and apparatus for continually forming spherical objects such as steel balls or the like which balls are utilized in various grinding processes which apparatus and method includes at least one longitudinally extending forming tube with means for rotating the same wherein a predetermined amount of material is introduced at one end thereof and the rotation of the tube along with the downward movement of the material will form the introduced material into a substantially spherical shape and thereafter providing forming dies for compressing the formed object into a more positive spherical shape of a hardened compressed quality.
