DG Khan has decided to implement state-of-the-art technology and has signed a contract with LOESCHE GmbH for the supply of three grinding plants for its new 9,000 t/d clinker production line at Hub in Balochistan province. DG Khan Cement Company Limited (DGKCC) was established as a private limited company under the management control of State Cement Corporation of Pakistan Limited (SCCP) in 1978 and started its commercial production in April 1986 with 2,000 tonnes per day clinker based on dry process technology.
Today, DGKCC is amongst the largest cement manufacturers of Pakistan with a production capacity of 15,000 tonnes per day. DGKCC owns three cement plants, two plants located at Dera Ghazi Khan and one at Khairpur Distt Chakwal. All the plants are based on latest dry process technology. At On 4th September 2015, DGKCC decided to implement state-of-the-art technology and signed a contract with LOESCHE GmbH for the supply of three grinding plants for its new 9,000 t/d clinker production line at Hub in Balochistan province. It is expected that Pakistan’s current cement demand 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 its decision to build this new production line in 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 1,050 t/h nominal capacity will be the biggest raw material mill in the world. In cooperation with LOESCHE, Renk has developed the COPE drive, this offering a redundancy of up to 8 motors at the motor end. As this power train retains the normal dimensions, the system is also suitable for retrofit drives in existing mills.
LOESCHE GmbH and Renk AG have agreed on exclusivity in marketing, application and development for the next 5 years. With the new COPE drive, which DGKCC decided will be installed in both the raw material and clinker mill, it will be possible to split the total drive capacity. 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 favourable solution with respect to DGKCC’s supply inventory as all key parts will be interchangeable among the cement and the raw mill. With this project, DG Khan Cement Company has become a trendsetter, being the first cement plant establishing 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 all mechanical equipment, and together with LOESCHE Automation GmbH, it will install the electrical engineering package along with all hardware supply — from steel structures to electrical equipment and automation. 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.
