Microlite aluminum oxide ceramic is one alumina ceramic material made of high purity α – Al₂O₃ and processed by several ceramic manufacturing procedures with crystal grain size less than 6μ m and the main crystal phase is corundum. This material has the character of high melting point, ultra high hardness, good mechanical strength, anti-corrosion, good insulation. Corundum is naturally of ultra high hardness, Mohs 9 in scale, almost equal to diamond in hardness.

Aluminum oxide has several crystal structure, mainly are the mesophase created by the dehydration of aluminum hydrate. The familiar crystal forms of alumina oxide are α – Al₂O₃, β – Al₂O₃ and γ – Al₂O₃.

Microlite aluminum oxide ceramic grinding ball as one most ideal grinding media is mainly used in the production of top grade sanitary ware and ceramic tiles. Using the microlite aluminum oxide ceramic grinding ball can improve productivity, reduce consumption of energy in clay grinding, reduce the requirement of natural grinding media like pebbles and preserve the ecological environment.

This the H.S. code for alumina ball products export.

69.03: Other refractory ceramic goods (for example, retorts, crucibles, muffles, nozzles, plugs, supports, cupels, tubes, pipes, sheaths and rods), other than those of siliceous fossil meals or of similar siliceous earths.

6903.2000 — Containing by weight more than 50% of alumina (Al₂O₃) or of a mixture or compound of alumina and of silica (SiO₂).

69.09: Ceramic wares for laboratory, chemical or other technical uses; ceramic troughs, tubs and similar receptacles of a kind used in agriculture; ceramic pots, jars and similar articles of a kind used for the conveyance or packing of goods.

6909.1200 — Articles having a hardness equivalent to 9 or more on the Mohs scale.

China official holiday for the 2009 Chinese Lunar New Year is January 25 – January 31, total 7 days, and our office will be closed during the holiday.

We will come back to office on February 01.

Best season’s greeting!

Ball forming and kiln firing is the two key procedures in the alumina ball manufacturing. See what we are doing in this two procedures to guarantee the high quality of alumina ball produced by HuaMing Alumina Technology Ltd.

Compared with other ball forming methods, our applied cool isostatic pressing can overcome the defects of hollow, delamination and low tightness, increase the production rate and improve the wear resistance of our alumina grinding ball.

The ball forming pressure has significant influence to the density of the unfired alumina ball, shrink in firing and the firing temperature. In certain pressure range, when increase the ball forming pressure, the density of the unfired alumina ball will be increased and the shrink in firing will be decreased.

The ball forming pressure also can influence the firing temperature; the different pressure in ball forming can lead to 20 -50°C difference in alumina ball firing temperature.

The ball forming procedure is very important to the quality of alumina grinding ball.

Firing is the key to determine the alumina ball quality, so prepare the ideal heating curve is the key factor to guarantee the quality of alumina ball.

We, HuaMing Alumina Technology Ltd., adopt the full automatic 1700°C tunnel kiln enable the continuous production and increased the production capacity.
