KORFEZ ENG: tailor-made solutions for ball mills

10 April 2015

KORFEZ ENG. is a technical consultancy located in Neubeckum, North Rhine-Westphalia, Germany. The company delivers high-alloy wear- and heat-resistant steel castings for the cement and mining industries.

The products are manufactured in collaboration with Turkish partner, KORFEZ DOKUM, which, since 1988, produces steel castings from 0.500 kg to 6.000 kg on a built area of 12,000 m².

KORFEZ has over 300 employees and a production capacity of approximately 10,000 tons per year. Since 2011, KORFEZ ENG. has increasingly focussed on engineering and manufacturing tailor-made solutions for ball mills used in the cement and mining industries, primarily system components such as mill shell linings and mill diaphragms.

South Africa: slag mill conversion project
In November 2014, KORFEZ ENG. was chosen to perform a complete mill conversion project for a new customer in South Africa.

In close collaboration with the slag cement producer, an optimised solution to replace the currently installed clamped mill shell lining was determined. The reason for choosing a bolted wave lining system for the 3.80-m-diameter slag mill, was due to the fine grinding media composition with very small grinding balls.

For this lining system it is considerably easier to perform the assembly and installation, as well as the maintenance of the wave liner plates, and storage is also made easier as it has many equal parts.

The KORFEZ shell lining system is expected to provide significant process improvements. The mill components are currently being delivered to the customer.

Germany: mill shell lining conversion for a leading cement group
In January 2015, the installation of KORFEZ ENG’s second compartment mill shell lining was successfully concluded for a cement producer in Germany. A combination of lifting and classifying liners made of extremely durable cast steel with 27% chromium content was delivered, not only to protect the mill tube from wear, but also to ensure a well-balanced material flow throughout the complete grinding chamber.

The mill shell lining system, for application in a two-compartment cement mill with a diameter of 4.40m, has a total compartment length of approximately 10.25 m and has been designed in the technical sales office in Neubeckum. The cement plant staff reported that the assembly was completed in only one week – properly and successfully.
