A right circular hollow cylinder (or cylindrical shell) is a three-dimensional region bounded by two right circular cylinders having the same axis and two parallel annular bases perpendicular to the cylinders' common axis, as in the diagram. Let the height be h, internal radius r, and external radius R.
A cylindrical grinder used to grind, or mill, raw materials for use in ceramic bodies or glazes. Size reduction of the feed materials is achieved by a combination of impact and attrition resulting from the tumbling of hard media, such as pebbles, inside the mill during the rotation of the mill.
