1. Smelting Process
We adept two different furnace line, stable furnace and tilting furnace.
2. Crushing and Sieve Process
Customers may prefer different grit shape with correlated with the grit bulk density. It depends the usage of BFA grain in sandblasting process, making grinding wheels and abrasive cloth, etc. A combination of sharp and block grains is also possible. For satisfying clients different request, we can finish crushing process in our Ball mill, mill roller and Bamarc machine.
Clients from worldwide may have different sieving standards. We are available to sieve based on FEPA, ASTM, JIS and China GB standard. In addition, we are also on the position to sieve according to clients special requirements.
3. High Temperature Roasted Process
For making high quality abrasives products, the BFA grain need to calcined or roasted in high temperature of 1050℃ or 1350℃ after sieving. By doing this, the BFA grit hardness, abrasive resistance and hydrophilic.Besides, it is also avoiding the expansion and crack in producing abrasives.
4. Lab Test for Physical and Chemical Property
We do the test inspection before sending clients sample, and after finishing production for each contract. Usually, we test chemical composition, bulk density, magnetic material and grain distribution.
