loesche announces four mill contract with pioneer cement - cement industry news from global cement

Pakistan: Germanys Loesche has been awarded a contract for four vertical roller mills by Chinas Chengdu Design & Research Institute forPakistans Pioneer Cement, which is expanding its production capacity to 8000t/day in the Chenki/Khusab district in Punjab Province. The contract includes a 630t/hr Loesche mill for grinding raw meal, two Loesche finish mills, each with a capacity of 235t/hr and a 60t/hr Loesche coal mill.

Loesche Dynamic Classifiers will be used to ensure the appropriate fineness. The patented Vortex Rectifier and an optimised flow characteristic produce significantly lower energy consumption and therefore lower operating costs.

Efficient dedusting of the raw material mill is carried out using two HURRICLON systems from Loesches A TEC subsidiary. This gives the advantage of reducing the total energy requirement of the plant due to the low pressure loss and high degree of separation. It also creates savings in steel construction and installation due to the significantly lower weight compared to conventional cyclone technology.

dg khan opted for pathbreaking grinding technology from loesche gmbh with innovative cope drive technology

DG Khan Cement Company Limited (DGKCC) was established as 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 tons 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 tons 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.

On 4th September 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 9,000 t/d clinker production line at Hub in Balochistan province.

It is expected that Pakistans demand of cement may increase due to expected government spending on infrastructure projects. Revival activities may result in additional demand of 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.

In August 2015, a team of 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, this offering a redundancy of up to 8 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 an exclusivity in the marketing, application and development for the next 5 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 in the production facility of Renk. The audience experienced starting of this huge drive perfectly smooth and appreciated this with a big applause.

In addition, LOESCHE will deliver both mills, the raw material and the cement mill, according to the unique LOESCHE unification concept introduced into the grinding technology many decades ago. This will provide a favorable solution with respect to DGKCCs 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 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 Pakistans market leader. Two different products are being produced namely Ordinary Portland cement and Sulphate Resistant Cement. The consistently increasing trend in the Pakistanian market share reflects the customers satisfaction on DGKCCs quality and services. It also reflects the precise companys policies and marketing strategies to enhance market share.

This new cement plant at Hub in Balochistan will support and add to DGKCCs strategy as it will become one of the most modern cement plants of 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 sustainable basis in the economy of Pakistan will become reality. The LOESCHE team is proud being able to support DGKCC to realize this vision and prepare for the future.

loesche vertical roller mills for the comminution of ores and minerals - sciencedirect

LOESCHE vertical roller mills are widely used for the comminution of raw materials in the cement industry, for the comminution of clinker and blast furnace slag and for the production of pulverized coal for cement kilns, blast furnaces and power plants. Recent research has shown, that the application of these vertical roller mills in dry grinding of ores and minerals can lead to significantly better recovery rates and higher grades when compared to conventional grinding. Since mid 2000 a LM 50.4 has been in operation for the comminution of a phosphate carrying pyroxenite ore with a capacity of 825 t/h at a D80 of 480 m.
