There are many types of high alumina bricks, including special grade, first grade high alumina brick, second grade high alumina brick, and third grade high alumina brick. Of course, the price of special high-alumina bricks is the best, and the aluminum content is the most. Today, I will introduce the production process of the next special high-alumina bricks: the production process of high-alumina bricks and multi-clinker clay bricks are similar, but the difference lies in the clinker in the ingredients. The proportion is relatively high, which can be as high as 90-95%. The clinker needs to be sorted and sieved to remove iron before crushing. The firing temperature is relatively high. For example, when high alumina bricks such Sicut et ego et II sunt accensus in cuniculo kiln, sunt plerumque MD ~ MDC gradu {{}} XIII
