Abstract:
1. An apparatus for producing ceramic balls using a rotation manner comprising: a rotary chamber having an inlet through which ceramic powder is input, and a nozzle through which water, a binder, or water and a binder are sprayed, wherein a rotational speed of the rotary chamber is increased or decreased according to a size of the ceramic balls to be obtained; and a tilt adjuster adjusting a tilt angle of a rotary axis of the rotary chamber, wherein the tilt angle is increased for improving contact frequency between the ceramic powder and adjusted to ensure a smooth formation of the ceramic balls, wherein the rotary chamber has a polygonal roughened inner wall, which allows the ceramic balls to frequently come into contact with inner surfaces of the polygonal roughened inner wall, thereby forming hardened ceramic balls, and wherein a roughness of the polygonal roughened inner wall is varied according to viscosity of the ceramic powder and the size and strength of the ceramic balls.
