The casting grinding ball is made of chromium, austempered ductile iron, white cast iron and the like, the casting forming method mainly comprises metal sand sleeve casting, resin sand casting, iron mold sand-coated casting, lost foam casting tfkp and the like at present, the production method has advantages, but in the production process, the grinding ball needs to be fed through a certain riser and a runner to obtain the grinding ball with compact structure, and the casting mould of the casting ball needs to be formed by molding sand partially or completely. In contrast, the core structure of the grinding ball is loosened to a certain extent, and the utilization rate of molten iron is not high due to the existence of a feeding head and a pouring gate in casting production, and is generally about 80% or even lower; and the equipment investment for realizing mechanical and automatic production in actual production is large.
The casting ball is cast by adopting sand shooting for molding; some casting methods adopt solid mold casting, and vacuum pumping is adopted through coating and pouring. The process control of these processes is relatively complex. For example, the process flow of casting the grinding ball by using iron mold sand lining comprises the following steps: the method comprises the steps of heating a grinding ball model, sand coating and molding of an inner cavity of a grinding ball iron mold, checking a cavity after molding, removing floating sand, combining and fastening upper and lower iron molds, pouring, solidifying and cooling, fastening and loosening upper and lower iron molds, opening upper and lower iron molds to produce castings, cleaning sand shooting holes of the iron molds and residual sand in the inner cavity of the iron molds, and the like, wherein some procedures are difficult to realize mechanization and automation, and a large amount of funds and equipment are required to be invested.

The molten iron is filled in the grinding ball cavity of the metal mold under the action of centrifugal rotation of the metal mold, and the molten iron in the grinding ball cavity is fed to obtain the grinding ball with compact tissue. However, because only one group of grinding balls can be poured after the upper grinding ball metal mold die and the lower grinding ball metal mold die are combined, the production efficiency is low, a centrifuge is needed for producing one group of grinding balls, the same amount of grinding balls are produced, the operation time is long, and the workload is large.
