The production process of white fused alumina:
The production process of white fused alumina uses industrial alumina powder as a raw material, which is melted at a high temperature of more than 2000 degrees and cooled, and then melted by an arc. Crush and shape it, remove iron by magnetic separation, and then sieve various particle sizes. It has a high density, high hardness, and forms sharp particles.
1. Add conductive material to alumina powder, add to the electric furnace to dissolve, dissolve with electric current, cool, solidify and crush to form a white fused alumina block with alumina content exceeding 98%
2. Then, it is crushed through the Barmac production line and screened according to the particle size required by the customer. The particles are mostly spherical particles, commonly referred to as “granular sand”, and the internationally accepted size number is F4-F220.
3. The screened fine powder is screened by a hydraulic process, screened by a microscope in real-time, dried, and made into white fused alumina fine powder.
