J&L is the first independent supplier to manufacturer plate holders allowing customers the flexibility to choose quality and service from two different sources. Abitibi-Consolidated, Shawinigan, provides feedback of J&L’s first CD plate holder install.
Building on four decades of experience, J&L redefines refiner plate casting technology with PowerCast™. This new process offers customers of Hardwood, OCC, DIP, and Post Mechanical refining applications a better option for ultra-low intensity fine bar patterns. The Ultra-Bar with PowerCast Technology will maximize life, improve fiber development, and prevent bar bending and breakage in these tough applications at a cost lower than fabricated designs.
Pulp quality has always been an objective in OCC refining and is a necessary requirement for the pulp being fed to the paper machine. Many plate patterns are designed in an effort to fulfill this objective. Even though some patterns achieve the pulp quality desired, they tend to deliver less than satisfactory plate life. How can a mill increase plate life without sacrificing pulp quality? (ReverseFlare/PowerCast)
Recently, a mill wanted to increase plate gap and plate life in their SGW reject position while improving or at least maintaing quality and runnability. To accomplish this goal, a J&L Venturi design with a shallow holdback angle was recommended. The Venturi design produced a 100% bigger plate gap and 30% increased plate life… Plus, it improved runnability and fiberlength.
You paid for a complete CD refiner, but how much of it is actually working? The answer may surprise you. Whereas, logic would assume a CD with two zones would utilize both, this wasn’t always the case in the mills we surveyed. Find out how to make sure your refiner is working up to its ability.
Demanding applications requiring low and medium intensity refining can benefit from greater open area and taller bar heights. PowerCast patterns are the solution for high contaminant furnishes such OCC, NSSC, or high Kappa USWK with high shive levels.
Are your refiner plates prone to plugging? Do you want to increase plate life, capacity and efficiency? Do you want to reduce energy, plate and maintenance costs?
