The difference between activated alumina ball and high alumina ball

 The calcined temperature of activated alumina ball is 350-600 degrees Celsius, and the calcined temperature is low. After calcined, the ball has a characteristic porosity, so that it has a good adsorption capacity. The calcination temperature of the high aluminum ball is 1300-1500 degrees Celsius. The high temperature will solidify the material, and the inactivity will increase its strength and wear resistance. High aluminum ball is mainly used in grinding industry, generally suitable for grinding powder material ball mill.
Activated alumina ball forming process adopts disk forming, the general diameter is 3-5mm, the ball is smaller than the high aluminum ball, the yield is larger. The larger ball diameter of the high aluminum ball is generally formed by isostatic pressing process, while the smaller ball is generally made of disc roll.
The bulk density of activated alumina ball is large, and the internal void ratio should not be too high, so as to lose the active adsorption capacity. The high aluminum ball can increase the accumulation density, and the higher the accumulation density is, the better its wear resistance will be.
