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.
