wonder cement orders eighth vertical roller mill from gebr. pfeiffer - cement industry news from global cement

India: Wonder Cement has ordered its eighth vertical roller mill from Germany-based Gebr. Pfeiffer. A MPS 3070 BK type mill has been selected for grinding petroleum coke and coal. The throughput rate for pure petcoke grinding will be 40t/hr with a product fineness of 2% R 90m. The mill will be equipped with an SLS 2900 BK type classifier. Due to the high abrasiveness of Indian coal, the mill and classifier will be designed with a correspondingly robust wear protection. The new mill will support the fourth 8000t/day production line at the producers plant at Tehsil Nimbahera, Chittorgarh in Rajasthan.

Most of the components of the coal mill will be manufactured by Gebr. Pfeiffer India including the housing and foundation parts, the grinding bowl and a large part of the force-transmitting parts. Delivery of the mill is scheduled for the end of 2021. Commissioning of the entire kiln line with the new grinding plant is scheduled for spring 2022.

India is the world's second largest producer of cement and produces more than 8 per cent of global capacity. Due to the rapidly growing demand in various sectors such as defense, housing, commercial and industrial construction, government initiative such as smart cities & PMAY, cement production in India is expected to touch 550600 million tones per annum (MTPA) by the end of year 2025.

With recent growth and success journey there is also a threat approaching to cement industry that its input cost is increasing. Power cost, fuel cost, raw material cost have doubled up in recent years whereas cement price has not hiked in that fashion. Also 40% of the cement production costs are energy costs out of which more than 60% of the total electricity is used in grinding circuits. In order to survive and sustain in the market they need to increase their profitability which can only be achieved by increasing productivity and reducing power consumption. High productivity and low power costs can be achieved by increasing output, lowering breakdowns and optimizing the energy consuming grinding process.

The objective of the study, is to draw attention to the need of Cement grinding process optimization to minimize power consumption and achieve higher productivity. In the study the advantages of vertical roller mill are discussed over ball mills. VRM construction, its process and parameters which affects the performance and productivity of vertical roller mill are discussed. Also the consequences of variations in parameter explained. With proper optimization of these parameters, the productivity of vertical roller mill can be improved and performance stability can be achieved by addressing root causes.. This study can benefit the organizations using VRM and are not able to utilize its full productivity due to some bottlenecks or constraints.

Wonder Cement belongs to a family company based in Udaipur, India, which apart from other businesses is active in the cement industry. As Gebr. Pfeiffer already supplied 4 mills of the type MPS for raw material and pet coke grinding, the customer has now decided to use a vertical roller mill also for cement grinding.

Until now, the customer has used combined grinding plants of another supplier for grinding cement. Besides the lower specific energy consumption of the MVR mill, the fact that it can be used for grinding and simultaneously drying moist feed materials played a key role his buying decision. In India a trend towards the use of stored fly ash replacing more and more dry fly ash from coal power plants as cement constituent can be identified. This type of fly ash, stored in the open, has a very high moisture content and if processed in a grinding system different from the MVR mill would have to be dried separately. The customers engineering team called in HOLTEC, a consultant based in Gurgaon, close to New Delhi. Its good experience with PFEIFFER MVR mills which are in operation in other Indian cement works has led the consultant to suggest changing the grinding system and switching to a Pfeiffer MVR mill. Gebr. Pfeiffer SE, Kaiserslautern, will supply a mill of the type MVR 6000 C-6 with a 5,280 kW drive that will be set up in Nardana, in the state of Maharashtra. It will produce mixed cements with finenesses of up to 5%R 45 m. The customer was particularly keen on grinding relatively hot clinker in the mill while, at the same time, the cement outlet temperature is reduced. Added to this was the fact, that the concept offered the possibility of using cold clinker from stockpiles. The offered MVR mill, which is currently experiencing a high demand around the world, is equipped with six actively redundant grinding rollers. This means that all six grinding rollers take part in the grinding process. When it comes to scheduled maintenance works, two opposite grinding rollers can be swung out and the mill can continue production with the four remaining rollers. Even in the case of an unplanned outage of one of the grinding rollers, the mill can continue in operation while the roller under service is being worked on outside the mill.

The core components of the mill, such as tension system and grinding rollers, will be supplied by Gebr. Pfeiffer, Germany. The grinding bowl and the gearboxes for mill and classifier will also be supplied from Europe. The parts for housing and foundation, the supports for the grinding rollers and most of the parts of the integrated high-efficiency classifier of the type SLS 5600 BC will be provided by Gebr. Pfeiffer (India) Pvt. Ltd., Pfeiffers wholly-owned subsidiary in Noida. It will also supply most of the equipment required to complete the grinding plant, including plant fan. For all components which will be procured by the customer, he will receive the corresponding specifications. Delivery is scheduled to be effected before the end of this year.
