DG Khan opted for grinding technology from Loesche GmbH with COPE drive technology

DG Khan Cement Company Limited (DGKCC) was established as a private limited company under the management control of the State Cement Corporation of Pakistan Limited (SCCP) in 1978 and started its commercial production in April 1986 with 2000 t/d clinker based on dry process technology.

Today, DGKCC is amongst the largest cement manufacturers of Pakistan with a production capacity of 15000 t/d. DGKCC owns three cement plants, two plants located at Dera Ghazi Khan and one at Khairpur Distt. Chakwal. All the plants are based on the latest dry process technology.

On 04.09.2015, DGKCC decided to implement more state-of-the-art technology and signed a contract with Loesche GmbH for the supply of three grinding plants for their new 9000 t/d clinker production line at Hub in Balochistan province.

It is expected that Pakistan’s demand for cement may increase due to expected government spending on infrastructure projects. Revival activities may result in additional demand for construction material. DGKCC as the market leader anticipates this development with their decision to build this new production line in the Balochistan province.

It was decided that at Hub, for all grinding processes Loesche vertical roller mills will be installed. Thus, the contract comprises one raw material mill for 654 t/h raw meal with a COPE drive, one cement mill for 445 t/h OPC with a COPE drive as well as a coal mill for 66 t/h.

The raw mill with 1050 t/h nominal capacity will be the biggest raw material mill in the world. In August 2015, a team from DGKCC accepted the invitation of Loesche GmbH to participate in the presentation of the first COPE drive at Renk AG in Augsburg. In a cooperation with Loesche, Renk has developed the COPE drive, offering a redundancy of up to eight motors at the motor end. As this power train retains the normal dimensions, the systems is also suitable for retrofit drives in existing mills. Loesche GmbH and Renk AG have agreed on exclusivity in the marketing, application and development for the next five years.

On this occasion in Augsburg, the new technology and the functioning together with vertical roller mills was explained in detail, the COPE drive was then presented live at the production facility of Renk.

With the new COPE drive, which DGKCC decided to have installed in both the raw material and clinker mill, it will be possible to split the total drive capacity. In addition, Loesche will deliver both mills, the raw material and the cement mill, according to the unique Loesche unification concept introduced into grinding technology many decades ago. This will provide a favorable solution with respect to DGKCC’s supply inven-tory as all key parts will be interchangeable between the cement and the raw mill. With this project, DG Khan Cement Company has become a trendsetter being one of the first cement plants to establish a single solution for the grinding of raw material and cement with vertical roller mills equipped with the innovative COPE drive technology from Renk AG.

Loesche GmbH will be responsible for the full mechanical equipment and together with Loesche Automation GmbH for the electrical engineering package along with all hardware supply from steel structure to electrical equipment and automation.

Up to date, DG Khan Cement Company is Pakistan’s market leader. Two different products are being produced namely ordinary Portland cement and sulphate resistant cement. The consistently increasing trend in the Pakistani market share reflects the customer’s satisfaction with DGKCC’s quality and services. It also reflects the precise company’s policies and marketing strategies to enhance its market share.

This new cement plant at Hub in Balochistan will support and add to DGKCC’s strategy as it will become one of the most modern cement plants in the world with the latest, most innovative and effective grinding technology.

With this project, their vision to transform the company into a modern and dynamic cement manufacturing company with qualified professionals and fully equipped to play a meaningful role on a sustainable basis in the economy of Pakistan will become reality.
