Ultrafine Grinding Process

Posted in: , on 4. Sep. 2008 - 10:57

Hi,

We are interested in a limestone mine for GCC production. At the moment, we are trying to achieve GCC powder of 1-5 micron.

We intend to grind limestones and to produce GCC using three successive processes. The first process is to grind down to 30 micron and the second process is to grind to the final ultra-fine size of 1-5 micron and the third process is the separation of the powders in commercial families.

Our limestone has a very high chemical purity (CaCO3 of over 97%) but rather low Whiteness-Index (below 50) and we would like to find methods in our second grinding process and in the separating process to achieve the final particle size of 1-5 micron and at the same time, improving the Whiteness-Index to as much as possible.

Please offer your advice or available service for our considerations.

Thanks

Good day to you. General Kinematics has done many fine grinds including GCC. Our Vibra-Drum mill can achieve micron sizes with energy savings, low media wear, and low contamination as compared to other technologies. Please let me know if you have interest in us running a sample of your material in our demonstration laboratory.

Best Regards,

Todd

Zenith crusher and breakday -

I have not said it politely but have instead deleted several of your sales messages from this Forum.

You do not seem to understand the value of a technical Forum. People ask specific questions, see above by fleetwoodjazz, and expect replies and an interesting discussion. If you cannot give an advice to a certain problem, stay away and do not advertise your products.

You can post your "new equiment" messages under "News from Industry", but you have also done this excessively in the past.

Hi,

Thank you for your replies. Please note that we need to improve the Whiteness-Index together with grinding GCC to 1-5 micron. If your solution is only to achieve ultra-fine grinding size then I would not be interested.

Please contact me at cao.minhduc@rentaport.be

Thanks

Brightness usually goes up when a product gets ground finer. If you are getting contamination from either media/parts wear it will lower your brightness. The use of a ceramic media and liner would help this issue greatly. Also if you have a grit contamination it can also darken your end product.

In each case I have had success with selectively grinding and using ceramic media to make a brighter product. If you have questions please feel free to PM or e-mail me with specifics.

Best Regards,

Todd

You Can Get A Brighter "Whiteness"...........

Posted on 10. Dec. 2008 - 06:09

........as you grind limestone down to the micron size you are specifying. However, you will NEVER hear any manufacturer of grinders saying they can take a material that is a "50"" (on the light scattering scale of 100) and tell you by SIMPLY GRINDING that you will get into the 90"s range. Many groups add titanium oxide to brighten materials...but that can be costly and can also have an adverse effect on the application.

I wish you the best...but if you want 90+ brightness then your stock/source material needs to be within a reasonable range of that #.
