Let me introduce my company:

We are Alarabia for trading and industry we are working for raw plastic material and raw building material.

Now we bought a big factory for grinding material like calcium carbonate. We have 8 tube mills about 20 t/h and 4 ball mills 10t/h.


I think you can help us the find a German company to give us the machines.

I hope to see you face to face in Germany or in Egypt.

Best regards

Dear Mr. Ahmed Saad,

With high interest we noted your thread.

In our understanding your requirement will be 97% < 1 µm. Please be informed that such fines will be only possible by wet grinding and not by your existing dry grinding mills.

We are the manufacturing company for dry processing plants and wet processing plants as well. We have already an agent for the Egyptian market.

The adress is:

Ultra Fine Grinding

Posted on 19. Jun. 2007 - 10:59

Dear Mr. Saad,

to quote the right grinder, it is needed to know a little bit more about the particles.

Feeding size?

how many particles should be below 1µm (50%, 95%, 97%, 99%)

Then what should be the throughput rate for thze grinder?

Perhaps it is possible to classify after the ball mills most of the ultra fine particle and the fed the rest to a ultra fine grinder.

Please come back for a closer discussion. Unfortunately we do not have yet a representative in egypt, but I'm able to discuss all the matters with you if it is needed.

For further question do not hesitate to contact me.

P.s.: My Father worked many years in Egypt, Alexandria (from 1987 until 1993) for an egyptian company in Alexandria, so would be nice to come back again to egypt. Nice greetings

Dear Mr. Saad,

PMT-Jetmill is a producer of ultrafine grinding and classifying equipment. Our Jetmills are most suitable for laminar, soft minerals like talc, mica, graphite, etc.

Our classifying systems are capable of producing ultrafine products throughout the whole range of industrial minerals. Due to the patented positive pressure operation the system can be operated with higher shear forces to have the required dispersing abilities to obtain a high yield.

Classifying in this fineness range requires this dispersion to push the efficiency of the classification to an economic level.

With this a yield, even in the finest range of > 50 % can be obtained.

We are looking foward to receiving detailed information on your request like PSD of the feed and final products, requested capacities, etc.

With kind regards,

Dr. Jürgen Roth

Dry Grinding Unit

Posted on 23. Jun. 2007 - 09:17

Dear Mr. Ahmed Saad,

We thank you very much for your interest in our equipment.

We introduce ourselves as one of the leading manufacturer of complete micromising plant starting

from crushing unit to micromising.

As regards the classification systems, we have technical collaboration with M/s. IVA Industrieberatung GmbH, Germany.

We have been manufacturing equipments for Calcium Carbonate grinding in our Country since last 12 years. Right now, we have 3 ton per hour - d97 = 8 microns output Ball Mill running continuously.

We have been seen your requirement regarding dry fine grinding to 1 micron particle size. Please note that dry grinding shall not give you d 97 = 1 micron. In this case, we shall have to go through wet grinding mill.

We request you to send us your exact specifications with regards to your requirement of exact particle size and the capacity required for that particle size.

We also request you to send us your all postal address with complete details etc. so that we can communicate better.

Thanking you,

Yours faithfully,




The Comments On Ultra-Fine Caco3 Powder Grinding From Wuxi China

Posted on 23. Jun. 2007 - 10:53

Dear Mr. Ahmed Saad,

Regarding your inquiry of ultra-fine CaCO3 grinding plant, we have the following comments and experience to share with you.

In China, the similar CaCO3 grinding plants generally would like to get the final products with the fineness: 5 micron: 97%. Among it, the powder less than 2 micron is about 70%.

We made an experiment to get the product on the fineness: less than 2 micron. In 2.2m (diameter) x 6m (length) ball mill, with dry process, the output is only 300kg/hour.

In ultra-fine powder production with dry-process, the key equipments are grinding equipments and classifying equipments. At present, in dry production, it is difficult to use current classifying equipment and technology to get 1 micro final product: 1 micron: 97%. In China, we just can achieve 2 micron: 97% with dry process. We are limited to classifying equipments, instead of grinding equipments.

Please confirm us the fineness of your final products. If possible, we would like to help you to select proper types of equipments.

P.S.: Our experience in ultra-fine CaCO3 powder grinding industry

In 1994 we designed the first super fine powder pulverizing ball mill production line and the Boltless Ball Mill Liners for it in China, which can achieve ideal output on the fineness of finished products with 2Ìm ~ 90Ìm. In µ2.2 x 5.5m ball mill, the capacity is 3.5mt per hour on the fineness between 2Ìm and 10Ìm.

In 2000, we designed the first set of Boltless Liners applied in a super fine powder vibrating mill in China.

In 2003, we manufactured and installed ball mill liners used in the largest super fine powder ball mills for Anhui Guofeng Nonmetal Hi-tech Material Co.(Jiuhua Calcium Co.) in China. Ball-mill-super-fine-powder-grinding process mainly relies on liners.

In 2005, we designed, manufactured and installed Boltless Ball Mill Liners for µ2.2 x 6.5m ball mills for CaCO3 grinding plants in Guangxi province and Henan province. On the fineness of less than 10 micron, the capacity is 4.5mt per hour; On the fineness of less than 2 micron, the capacity is 3.5mt per hour. It has achieved leading level at home and abroad.

Should you have any questions, please feel free to contact us.
