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.

Comparison between high alumina linings brick and the rubber linings.

Comparison of advantages and disadvantages.

Aspects on quality:

High alumina linings brick.

• Inner quality: High quality Al₂O₃ is the main material, high purity.
• Grinding lost: Very good anti-grinding nature, about 1/4 to natural stone linings that is 0.02% ~ 0.027%.
• Material slurry: High purity material, slurry is very thinner.
• Other aspects: Anti-erosion, high density, high mechanical strength.

Rubber linings brick.

• Inner Quality: High organic ingredient, easy intermixes into slurry.
• Grinding lost: Near to medium / high alumina linings brick.
• Material slurry: Has affect on degree of whiteness, easy cause needle-like holes.
• Other aspects: Cushion affect to grinding, low efficiency.

HuaMing Alumina Technology provides high quality mill linings alumina brick for both batch and continuous grinding ball mill. The high density of the alumina brick can expand the milling volume and increase the ball mill productivity.

PRESENTATION

We are “high density” Alumina (Al2O3) grinding media producer (balls, cylinders and bricks for linings). As CTI Cerámica Técnica Industrial, S.A. we started producing in 1984, becoming immediately the most important local market supplier mainly at the Ceramic Industry. Early 90’s we significally increased our production creating at the same time an strong, and very active export department, which actually have let us to compete in more than 35 countries in the world. Nowadays we are exporting a 75% of our total production capacity and even we are market leaders in some of those countries. During a period of almost seven years (from 1997 to 2003) we were part of Ferro Corporation and today we belong to a financial group called CERCO Llc under the name of CTI GRINDING MEDIA, S.L. WE ARE THE ONLY PRODUCER IN SPAIN OF SUCH PRODUCTS.

The range of products we manufacture is as follows:

- Alumina Balls: Ø 60, 50, 45, 40, 20, 25 and 20 mm.
- Alumina Cylinders: Ø 32 x 32, 25 x 25, 19 x 19 and 13 x 13 mm.
- Alumina linings for ball mills: thickness 45, 50, 65 and 75 mm.

Our Grinding media products are used for milling (grinding) all kind of raw materials at the following industries:

- Ceramics (floor and wall tiles, mosaics, glass, sanitary ware, tableware)
- White cement
- Mining and raw material suppliers
- Frit, pigment, glaze, color producers
- Painting plants

The market demand of “high density” Alumina grinding media products is increasing year after year due to their efficiency, lowest contamination of the product and energy saving.

The above is one world famous alumina ball manufacturer located in Spain, we, HuaMing Alumina Technology, here will prepare one list of alumina ball manufacturing companies, we will continue work on it.
