Alumina Balls Product

Alumina ball is made of commercial grade alumina (α aluminium oxide) by cool isostatic pressing and high temperature (e.g. 1480°C) kiln firing & sintering. Alumina ball has top 5 outstanding features:

• High density, 3.6 g/cm3.
• Ultrahigh hardness, Mohs scale 9, second only to Diamond in mineral.
• Good corrosion resistance, resistant to most acids and Alkalis.
• Excellent wear resistance, very low wear loss, less than 0.15‰.
• Uniform and regular in shape

Alumina balls can be divided into 2 main classifications:

Alumina Grinding Media

• Alumina Grinding Media
• Catalyst Bed Support Media

Alumina Grinding Ball

The alumina grinding media is developed originally to meet the requirement from the ceramic tile industry for increasing productivity of frit and pigment grinding. Compared with the natural cobblestone, the alumina grinding ball has more outstanding and reliable performance. Choose alumina grinding ball as your ball mill grinding media can significantly increase productivity, saving time and power and the alumina grinding media is more environment friendly.

Facts between alumina grinding media and natural cobblestone

• Bulk density: Alumina grinding ball bulk density: 3.6 g/cm3; natural cobblestone bulk density: 2.8 g/cm3.
• Hardness: Alumina grinding ball Mohs hardness: 9; natural cobblestone Mohs hardness: 7.
• Corrosion resistance: Alumina grinding ball has better performance in most acids and alkalis resistance.
• Wear loss: Alumina grinding ball Max. 0.15‰, natural cobblestone 1.4‰.
• Shape: Alumina grinding ball uniform and regular in shape, natural cobblestone natural, irregular in shape.

Alumina Support Media

Alumina ball is also used for catalyst bed support for oil refining, petrochemical and natural gas applications.

Alumina support ball features:

• High temperature resistance, the alumina support ball working temperature range is mostly 100°C to 1,200°C.
• High pressure resistance.
• Low water absorption rate.
• Chemical inertness.
• Resistance to thermal shock.

The main role of inert alumina ball is increasing the distribution of liquid and gas, holding and protecting the activated catalyst with low strength.

Notes:

• Bulk density: The weight of a material (including solid particles and any contained water) per unit volume including voids.
• Cobblestone: A rock fragment, usually rounded or semirounded, with an average dimension between 3 and 12 inch. (75 and 300 mm).
• Water absorption: A phenomenon in the transmission of electromagnetic radiation through a medium containing water molecules.
• Thermal shock: The name given to cracking as a result of rapid temperature change.

We need to sample your grinding media for suitability for our pigment refinment process.
 
Please give us a price for 2.5 kilograms of 12-15 mm alumina grinding balls.
 
We currently need to replenish stocks, typically we use 250 kilogram per month.
 
Thank you for your time.

After consideration, we believe the 15mm diameter to be our best choice, having used that size exclusively thus far.

Evaluation will take 5 days from the receipt of the sample. At that time we will be able to place an order (your pricing is very competitive), tentatively for the minimum order of 2 tons although personally I am pushing for 4 tons.

The sample of 400 grams will be sufficient. The 2.5 kilo estimate that was given to me was to charge a test mill with- this will not be necessary for my determination.

I did receive the sample. After a preliminary inspection (visual, as to dimensions, concentricity and hardness), the media was found to be acceptable.

The above is the correspondence with our USA customers for their requirement of alumina grinding ball.
