Beihai Huihuang Langjie Environmental Protection Technology (Group) Corporation
Inert High Alumina Balls Is a professional production supply activated alumina ball, aluminium oxide ball alumina ceramic ball, ceramics ball, regenerative heat ball al alumina ceramic company
By fusing alumina production YFA - WFA arc furnace in controlled conditions, block the
white material produces the color and density have mainly large crystal alpha alumina. Be
pressure, ground, spindle and precision in our new sizing plants get very consistent screen
size scores.
Magnetic iron from broken, rare earth magnets to ensure removed fe very low levels of
finished products. Shut down the size of the fractions are provided or precision mix
