Refractory aggregates are classified by material into clay, high alumina, corundum, siliceous, magnesia, magnesia alumina spinel refractory aggregates, etc.
High alumina aggregate refers to bauxite that has undergone high-temperature calcination, manual selection, processing, crushing, magnetic separation, and other procedures. Alumina aggregate, also known as refractory aggregate, with high grade referred to as high alumina aggregate, generally contains 55-88%.
High alumina refractory aggregate refers to refractory granular material that serves as a skeleton in the particle size composition of refractory materials. They are granular materials with a particle size greater than 0.088mm made by calcining, crushing or artificially synthesizing high alumina alumina.
High alumina aggregate is an indispensable raw material in refractory castables. It can be mixed with high alumina cement, fine powder, and water in proportion to produce high-strength refractory concrete. The high alumina aggregate produced by our company is made of high-grade dense alumina stone, which is calcined in a rotary kiln. High alumina aggregate has the characteristics of high density and easy operation during construction, and currently solves the problem of commonly used loose materials
The disadvantages of high porosity and low fire resistance in concrete made from fine powder. High alumina aggregates are widely used in refractory materials, kiln stove repair, refractory concrete, casting and other fields.
