High-alumina balls mostly refer to alumina balls with an alumina content of more than 90%. According to different contents, they can be divided into different categories. Because of their high strength, high hardness, high wear resistance, large specific gravity, small volume, high-temperature resistance, corrosion resistance, no pollution, and other advantages， they are widely used in various industries.
The technological process of high alumina ball powder forming hydraulic press:
Manual batching – ball mill pulping – mechanical stirring – pulverizing – powder homogenization – cold isostatic pressing – shuttle kiln firing
The high-alumina ball powder forming process is generally made by manual batching, static pressure forming by a high-alumina ball powder forming hydraulic press, and sintering in a high-temperature roller kiln. The inlet temperature of the high-alumina ball in the roasting furnace is 850-950°C, and the outlet temperature is controlled at 430-490°C.
