The disintegration process from ore to wear-resistant alumina lining brick

As we all know, wear-resistant alumina lining brick as a ball mill lining, with high hardness, high density, low wear, high regularity, corrosion resistance and other characteristics, widely used in ceramics, cement, paint, pigment, chemical, pharmaceutical, coatings, inorganic mineral powder processing and other industries, then wear-resistant oxide lining brick is produced from ore?

After the ore containing alumina is mined, it will be roughed into industrial alumina (γ-AL2O3), at this time the alumina content is about 65%, and then deeply processed into aluminum oxide powder (α-AL2O3), the alumina content will reach 99.5%, which can be used as raw materials for fine ceramics to be purchased by various ceramic enterprises.

After the aluminum oxide powder enters the factory, it is generally made first to ensure that the fineness of the aluminum oxide powder meets the production demand, and a small amount of binder, coarser particles and fine powder are matched to become billets, which are placed in the metal model and formed under pressure on the press.

The wear-resistant aluminum oxide lining brick after forming into the kiln car into the high-temperature tunnel kiln, after 1700℃ high temperature calcination, the finished lining brick is completed, and then the workshop master will be screened, polished, and then packed, according to the needs of customers to load the car and send to various places, play the role of wear-resistant lining brick.
