Advanced board making technologies for Sri Andal Paper Mills PM 4 in India

In a stride towards elevating the containerboard manufacturing landscape in India, Valmet delivered Sri Andal Paper Mills with advanced board making technologies for their new PM 4. 

The delivery includes:

• Three OptiFlo Fourdrinier headboxes to ensure precise profiles and optimal formation
• OptiPress Linear press section, which not only enhances the final product's quality but also offers high dewatering capacity and smooth operational performance
• OptiSizer Film size press equipped with a supply system to ensure even application of surface size starch across the paper width, resulting in uniform end product quality

To support the project's initiation, a startup package of spare parts and consumables was provided, alongside the Valmet DNA machine control system, Valmet IQ quality measurement system, and connectivity to the Valmet Performance Center together with remote On-Demand Expert Support.

The delivery also included paper machine clothing including formic fabrics, press felts, Valmet Black Belt shoe press belt and dryer fabrics.

The PM 4 started up in December 2022. “There are always challenges and unexpected issues in all major investment projects. In this project Valmet was extremely responsive, adaptable, and helpful in completing the project on time. We stayed on schedule and commissioned and produced sellable material within the allotted time frame.”, says Mr. G Chellamuthu.
