KHD is known in the industry as a modernization specialist and will integrate the new COMFLEX ® system to operate in combination with Askale's ball mill systems. Askale Cimento was convinced by KHD's expertise in increasing output by combining their current system with the most widelysold roller press technology in the cement industry.
KHD Humboldt Wedag mills are spacesaving, compact, high on performance and low on maintenance. This is primarily due to the support bearing design and the mill drive used. The mill is shellsupported, mounted on slide shoe bearings at both ends and made completely as a welded design.
Turkey: KHD has been awarded the contract to upgrade Nuh Çimento's existing ball mill grinding unit in HerekeKocaeli located in Marmara. With this upgrade, the plant will increase the grinding capacity from 212t/hr to 408t/hr at 4000cm 3 /g according to Blaine. This will be the largest upgrade project to date for KHD.

mills, include a considerably higher efficiency and a higher material throughput. This saves energy cost in the order of ca. 40 %, compared with a ball mill. During the development of the high pressure roller presses it became clear that the operating conditions and mounting conditions place extremely high demands on the bearings' capacity.

With this upgrade, the plant will increase the grinding capacity from 212tph to 408tph at 4000Blaine. This will be the largest upgrade project to date for KHD, the company noted in a statement.
Effect of Balls Hardness on Rate of Grinding. Tests by Coghill and Devaney show that the hardness of the balls has some effect upon the rate of grinding in mill. These results are plotted in Fig. and it is seen that, both for dolomite and chert, there is an increase in the rate of grinding with increasing hardness of ball.

Summary: The main trends concerning grinding processes in the cement industry are still higher efficiency, reduction of the power consumption and system simplicity. In the case of new orders, vertical mills have increased their share to over 60 % and ball mills have fallen to less than 30 %. It is somewhat surprising that the number of different grinding processes and mill types used by the ...

In some cases it was also indicated that the shape of particles from HPGR would be different; more angular as compared to ball mill products (Fig. 2) (Bleifuss, 1997).This, together with a high proportion of fines would allow a HPGR product to be suitable for pelletizing at a lower Blaine value from a presumed better packing and density in the generated pellets.
