Product Description

Product Description

White fused alumina is made from industrial alumina powder and smelted at a high temperature of over 2000 degrees in an electric arc. It is crushed and shaped duiring which process iron is removed by magnetic separation, and sieved into various particle sizes.

The outstanding feature is that the crystal size is small and impact resistant. Because White Alumina 99.4 Al2O3 Low Sodium White Fused Alumina Wfa Powder's processed and broken by a self-grinding machine, the particles are mostly spherical particles, and the surface is dry and clean, and it is easy to bond with the binder.

White Alumina 99.4 Al2O3 Low Sodium White Fused Alumina Wfa Powder has the characteristics of white color, high hardness, low toughness, high purity, excellent self-sharpening, strong grinding power, low heat generation, high efficiency, acid and alkali corrosion resistance, high temperature resistance, and good thermal stability.

Production Process

1)Raw material to factory→checkout→burdening→stirring→mixing→taking out the raw material,
2)Crushing→Mixing→Shaping→Drying→Firing→Inspection→Packaging and Shipment.
Quality Assurance
1)Going out the furnace→checkout→packing→qualified product→putting in storage→sale,
2)The process from raw to product are strictly tested by equipment.
1.Inspection and Control of incoming raw materials: according to the chemical content,raw materials are classified into different
levels to ensure quality of brick first.
2.Inspection and control of the process: during the production,every brick will be weighed twice strictly to reduce the error of
weight .
3.Quality audit by quality management: inspection of product standardization of quality of each product by process control and
experimentation, taking corrective measures timely whenever deviations are noted.
4.Before delivery, the inspectors will inspect the size,appearance, physical and chemical properties of brick again in factory.
