Coal Dust Refractory Application African Pegmatite
Coal dust is one of African Pegmatite s original products since 1971. It is used to coat refractory bricks before firing. We start with a high-quality coal and pulverise it into powder form. The coal dust is used as an additive which is mixed with clay and water and then the bricks undergo a firing process.
