|High Alumina content: 93% Min,High density: 3.63-3.65
low wear loss: 0.008%-0.001%, Fired by roller kiln with stable quality
1. Description of Products:
Alumina ball is widely used in Ceramic industry,cement industry, paint industry, Color industry,
chemical industry,pharmaceutical industry, coating industry and mining industry. The advantages
are: high hardness, good toughness, high density,good erosion resistance, regular shape etc.
2. Technical Datas of Products:
3. Standard Sizes:
Dia 1mm - Dia.25 mm (formed by rolling method).
Dia.30mm (formed by rolling method or by isostatic pressure).
Dia. 40 Dia.50 Dia.60 Dia.70 (formed by isostatic pressure).
(1) Core Technology:
Using the global best alumina grinding ball production technology originated from our over 12
years working experience as well as our frequent technical research. This core technology
enable us to produce high quality products continuously to satisfy the requirement of our
(2) Production system&equipment:
we are using high temperature roller kiln (totally 2 kilns with each 250 meters length and
Max.1650 degree centigrade) to sinter the alumina ball, which enable us to producer higher
and more stable quality alumina ball due to the temperaturedifference of roller kiln is much
smaller than that of tunnel kiln used by other manufacturers. The prominent features of
alumina ball sintered by roller kiln are :
1) higher density 2) lower wear loss 3) more stability of quality
The above mentioned technical data plays the most important role in the during the production of ceramic
and also the most important factors to the reduction of production costs.
