Product Details

high alumina ball for grinding Detailed Product Description:

refractory brick, high alumina brick, silica brick, fire brick, fire clay brick, alumina bubble brick.

The most competitive price,good quality,safty packing,prompt delivery time,and excellent after-sales services.

Lower ferric Oxide,lower porosity,higher refractoriness,higher density,higher CCS and exact tolerance.

Laurel high alumina ball are produced with selected bauxite chamotte by advanced process and strict quality control. The main mineral components are corundum and mullite phases. It features excellent high temperature mechanics and chemical corrosion resistance.
