Thank You and Best Regards,

Dear Sir,

Would you please check if you can supply alumina ball with 92% alumina.

Size 25mm, size 30mm and size 40mm with the price C&F MANILA NORTH PORT not higher than 1,000.00 usd/mt.

We will order first lot for trial first and if the quality is good we plan to order 15-30 mt per month.

Please advice.

Best regards,

HuaMing Alumina Technology Ltd.

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.
 
Regards,
Analytical Processes, Ltd.

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.

Ball milling and grinding media include high alumina ceramic grinding media ball and high chrome steel grinding media ball, produced and designed for milling and grinding of bulk powder or granular materials into finer powder forms. According to the hardness of the powder or bulk material to grind, you can decide and choose the media material. For wet, batch grinding, water or other liquids can be added as additives for friction reducing and cooling purpose.

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.

HuaMing mill linings alumina bricks are available in a wide range of thickness size from 25mm to 75mm to fit different sizes of ball mills.

Mill linings alumina brick has good performance in high impact, high abrasion resistance.

The following picture is showing how to install the alumina bricks correctly in your ball mill to achieve the best working preformace.

installation of alumina brick in ball mill

Type A: Correct installation, with trapezoid brick and rectangle brick combined correctly.

Type B: Correct installation, with only trapezoid brick applied.

Type C: Wrong installation.

Cement: Regular white Portland cement is suggested, if need corrosion resistant, then special cement is required.

Mill linings alumina brick types available: rectangle brick, trapezoid brick, flake brick, half-rectangle brick and half-trapezoid brick.

In general, for wet grinding, load the alumina grinding ball to 44%-51% of the ball mill volume can get the ideal grinding performance.

Formula for the load of alumina grinding ball:

M=π×(D²÷4)×L ×α×(1-β)×ψ

M: Alumina grinding load, in tons
π: Circumference ratio, 3.14
D: Ball mill diameter, in meters
L: Ball mill length, in meters
α: Ideal stacking volume of the alumina grinding ball to the ball mill capacity, 44%-51%
β: Void rate of the stacking alumina grinding ball, 40%
ψ: Alumina grinding ball density, in ton/m³

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.
