What is High Alumina Lining Bricks
High Alumina Bricks are classified into three categories according to their shape: rectangular bricks, trapezoidal bricks, and irregular bricks. All of them are hard, dense, neat, and durable. Alumina grinding bricks have high mechanical strength and superb anti-corrosion properties. High alumina lining bricks are also called 92 ceramic lining bricks, ball mill high alumina lining, microcrystalline wear-resistant high alumina ceramic lining bricks, molded by two-way hydraulic press, and sintered in the high-temperature natural gas kiln.

high Alumina ceramic Bricks applications
Utilized in industries such as pharmaceutics, cement, paint/pigments, chemicals, and coating, ceramic alumina lining bricks have a positive impact on the grinding process and production costs, and they’re good for the environment as they lessen the usage of power and pollution.
The main component of high alumina grinding bricks is Al2O3, which is a kind of refractory material. When the Al2O3 content of high alumina brick (Ceramic Alumina lining bricks) exceeds 90%, it is called corundum bricks.
Our firm produces Ceramic Alumina bricks of any category on demand, whether you want to use them as the wear-resistant inner lining of pipes and ball mills in the ceramic industry (one of the best options for ball mill lining), or to improve grinding efficiency in any other industry (medicine, coating, paint, cement, etc.).
high Alumina grinding Bricks advaNtages
With alumina ceramic lining bricks, grinding ball mills can be safe and sound for a long time —no routine maintenance required.
The chemical composition (92% alumina) and physical properties of the high ceramic Alumina bricks allow them to resist the impact on pipe walls and resist wear 266 times more effectively than manganese steel, without contaminating the ground material. Alumina grinding bricks are also unaffected by acid and alkali.
Wear-resistant ceramic alumina lining bricks is a product used for the wear-resistant lining of ball mills, which is widely used in ceramics, cement, paint, pigment, chemical, pharmaceutical, coating and other industries.
