The invention discloses a blank manufacturing device for a ceramic sphere with a built-in metal skeleton. The device comprises a stepping type conveyor belt and a lower semispherical mold conveyed through the stepping type conveyor belt. The lower semispherical mold at least passes four stations in the conveying process, wherein a conveying pipe is arranged above the first station, a device for containing a metal skeleton is arranged above the second station, an upper semispherical mold which is in buckled connection with a molding press is arranged above the third station, an inner cavity of the upper semispherical mold contains bagged powder, and a transferring device is arranged above the fourth station; an inlet of the upper portion of the upper semispherical mold is in a flat circle shape, an upper inner circular groove and a lower inner circular groove are formed in the inner wall of the inlet of the upper portion, and the bottom of the inlet of the upper portion is provided with a powder pressing hole communicated with the cavity of the upper semispherical cavity. The invention further discloses a blank manufacturing method adopting the blank manufacturing device. The method comprises the steps of preliminary filling of powder, skeleton falling, press fitting and rounding of spherical bodies, transferring of spherical blanks and the like. Ceramic spheres with built-in metal skeletons can be subjected to industrial automatic blank manufacturing.
Description
technical field [0001] The invention relates to the field of cement processing, in particular to a blank-making method and equipment for a ceramic ball with a built-in metal skeleton. Background technique [0002] The cement ball mill has the characteristics of strong adaptability to materials, continuous production, large crushing ratio, and easy speed adjustment to grind the fineness of the product. The working principle of the commonly used cement ball mill is that the material enters the mill chamber spirally and evenly through the feeding hollow shaft from the feeding device. There are stepped lining boards or corrugated lining boards in the chamber, and steel balls or ceramic balls of different specifications are installed inside. The rotation of the cylinder produces centrifugal force, which brings the steel ball or ceramic ball to a certain height and then falls, which has the impact and grinding effect on the material. Cement ball mill ceramic ball is a commonly us...
