PURPOSE: A composition for porous ceramic balls, the ceramic balls, and a manufacturing method of the same are provided to implement manufacturing processes without a chemical binder, and to improve absorption characteristic by maximizing the specific surface area of the ceramic balls through low temperature firing. CONSTITUTION: A composition for environmentally-friendly porous ceramic balls includes 10-20 weight% of kaolin, 20-30 weight% of natural zeolite, 10-15 weight% of magnetite, 5-10 weight% of elvan, 1-2 weight% of germanium, 5-10 weight% of tourmaline, and 10-20 weight% of 200mesh saw dust. A manufacturing method of the ceramic balls includes the following steps of: rapidly mixing the composition(1); arranging natural zeolite beads into a ceramic mold, spraying water while rotating the ceramic mold, and dispersing the composition(2); rotating the ceramic mold at a predetermined speed, and naturally drying the ceramic balls(3); and oxidation firing the dried ceramic balls at 800-850 deg. C(4).
