Extensive board machine rebuild for ITC Bhadrachalam mill


machine rebuild, automation upgrade and quality control package from Valmet for its Bhadrachalam mill. The rebuilt PM1 is planned to


I


produce high-quality lightweight coated board with a wide range of produced grades with start up scheduled for the fourth quarter of 2017. Valmet says the project is worth between €30 and €40 million. “ITC has been the pioneer in Indian paper industry for introducing folding box board of international quality standards,” says Sanjay Singh, chief executive of ITC Paperboards and Specialty Papers Division. “Our investment in a state-


of-the-art paperboard machine PM4 from Valmet way back in 1997 changed the experience


ndia paper maker ITC Paperboards and Specialty Papers has ordered an extensive board


of Indian printing industry. Selecting Valmet as partner for the new PM1 rebuild project is in line with our focus on enhancing the customer experience while aligning with the philosophy of ‘triple bottom line’, that is, for improved environmental, economic and social factors. With the support from Valmet, we will be introducing globally best available technology into this machine. I am sure that our customers are going to benefit immensely out of this project.” Petri Paukkunen, sales and marketing chief at Valmet, says: “Long-term relationship with the customer forms a solid base for this project – another PM4 machine at the site is Valmet- delivered and Bhadrachalam values it as their flagship board machine. Energy and raw material savings were among the most important issues that were


discussed in the negotiations of this new rebuild project. High quality furnish combined with our latest technology and automation and with the competence of ITC personnel give a good base for enabling an excellent end product. The rebuild will enable ITC to be among the best folding boxboard producers globally when it comes to lightweighing or improving bulk – leading directly to raw material savings.” ITC’s PM1 rebuild includes all the key technologies from headbox to reel and automation for machine and quality control. The 4.25m wire width machine will produce mainly cup board, but also solid folding box board, bleached board and art board grades with the basis weight range of 150-320 g/m2


. The


design speed will be 600 m/min. The machine features number of leading technologies that are


exclusive to Valmet. These include an OptiFlo


Fourdrinier headbox, OptiFormer Multi Fourdrinier forming section and OptiPress Linear shoe press with linear web run are important in high- quality board production. They enhance, for example, the end product surface and strength properties and productivity. Compared to other coated board machines in India, the machine is not equipped with Yankee cylinder, which often limits production. In the calendering section, a new type of a calender from Valmet OptiCalender Compact delivers reliable calendering results. Valmet DNA machine control and Valmet IQ quality control systems give accurate and reliable real-time data, which enables the optimizing of the entire production process and the end product quality.
