Alumina ceramic powder granulation 99%

In order to adapt to dry moulding in alumina production process or isostatic pressing molding, need the ceramic slurry is granular powder by spray drying formation and requires good liquidity, granule has the certain strength, and not get in the process of transportation and loading crushing, grading to a certain extent, when feeding tightly packed, with certain adhesion and lubrication properties, particle should not be mutual bond between... Such as granulation characteristics. Update the porcelain company specializing in the production of alumina powder granulation, through pressure centrifugal spray, spray and to take all kinds of grain size distribution and high liquidity in implementing the alumina particles.

Alumina powder granulation: categories: 80-99, toughening alumina porcelain porcelain, wear-resistant porcelain, steatite porcelain, color porcelain. Wet powder, porcelain powder. Features: low temperature, high density, a China powder non-stick mold, no crack, no pores, a China powder consistency is good. To adapt to the process: fast dry pressing, isostatic pressing, hot die casting, injection, spraying. [1]
