The traditional preparation of lightly burned magnesia ball is to add 80% lightly burned magnesia powder into the binder, then put it into the mixer for rolling, stirring and mixing for 15 to 20 minutes to form the mixture. The product is prepared by the belt conveyor and sent to the ball press, and then stacked. The products of light burned magnesia ball were dried after 48h and formed strength to prepare for sale.

This kind of magnesia ball is common in steel enterprises in the northeast and coastal areas, because there are rich magnesite resources in the northeast and brucite in the coastal areas. Especially in some chemical enterprises, the residue after chlorine gas preparation by electrolysis is basically an industrial waste, which can be prepared into magnesia ball with low price and good quality. The ball's position is higher than 65%.

In addition, the Magnesium Oxide content in the magnesium ball used by other enterprises is basically between 45% and 65%.
