The manufacturing process of white corundum

The production process of white corundum is made of industrial alumina powder, which is smelted in an arc at a high temperature of more than 2000 degrees and then cooled. Angular.

1. Add conductive material to alumina powder, put it into the furnace to energize to dissolve, spray water, cool, solidify, and crush to form a white corundum block with an alumina content of more than 98%.

2. After passing through the production line, it is crushed and screened according to the particle size required by the customer. Most of the particles are spherical particles, commonly known as "grain size sand", and the general international particle size number is F4-F220.

3. The screened fine powders are screened by hydraulic process, monitored by microscope in real time, dried, and made into white corundum micropowder.

4. Packing with 25 kg per bag, one ton as a unit for ton bag packaging, using floor scales for weighing, and choosing economical transportation methods according to customer needs.
