The papermaking process is essentially one of removing water. This process begins in the forming section where free water is drained from the pulp slurry using gravity and suction (vacuum) boxes.

Grooving suction rolls is a commonly undertaken process. Here are answers to some of the most frequently asked questions.

In future, Artificial Intelligence-driven applications will play an increasing role in transforming data into actionable new insights and optimization solutions. New AI-based systems can automatically classify and synthesize a large amount of data and learn the best operating parameters from historical data.

Canfor have been successfully employing the fast peCOD chemical oxygen demand (COD) method for improved effluent control and savings at the Prince George, BC Mills. 

The news headlines are regularly reminding us that critical infrastructure, industrial control systems and other cyber-physical systems are prime prey for nation states and hackers who want to cause real-world damage and chaos.

A market leader in the production of baby food was using a clamp style scraper system with thick, heavy steel blades. There were several issues with this type of system:

In today’s world of electrical energy, paper mills and box plants still prefer steam to deliver heat energy to their processes. To understand why steam technology remains the most effective process heat source for paper mills, box plants and many other process industries, it’s useful to understand its intrinsic benefits.

Many years ago now, as technology began to ramp up in the manufacturing world, process leaders began to focus on removing variabilities. The thought was, in operations, “If we can reduce variabilities in our processes, then our finished product becomes much more consistent.”

Mayr-Melnhof Karton in Kolicevo, Slovenia produces premium recycled and virgin fiber-based cartonboard grades on two board machines with grammages between 200 and 500g/m². Key markets are food, cosmetics, and pharmaceutical packaging, as well as other demanding applications.

If you type “alarm management” in a search engine, you will get hundreds of results including articles, papers, presentations and guides.

In my last blog post entitled ”Operational Readiness and Commissioning Plans: the Key to a Successful Start”, we looked at how BBA gets started with creating an operational readiness and commissioning plan that includes the following seven steps:

The pace of product development is ever accelerating, fueled by factors such as the rapid development of Artificial Intelligence (AI).

Very definitely. Liquid ring vacuum pump manufacturers publish capacity curves (CFM and vacuum level) assuming that the seal water is at a fixed temperature (typically 60°F).

The project’s goal was to reduce steam consumption in deaerators by using heat from the digesters (otherwise wasted) to heat demineralised water that was then used in the mill processes.

The MBN pumps are ideal for use in medium-pressure applications. They have a big variety of nozzle position options, thus providing flexibility during installation and simplifying the piping design.

Industrial electric motors are the “life blood” of your plant’s operation. The theoretical design life of an electric motor is 20 years or more. Yet many tens of thousands of industrial electric motors end up in the trash pile prematurely. This results in an enormous loss for industries across the board.

It depends. The drive load increases exponentially as the dryer speed increases, until the condensate goes into a rimming condition. 

A pulp mill was having issues with its pulp drying machine evacuating condensate and the rotary joints and piping were leaking.

The production of paper and fabrics includes the handling of rolls and reels at the end of the production process. These rolls must be moved from the forming or primary processing machines to other machines for further processing, or they must simply be stored correctly. Automatic guided vehicles (AGVs) are often used to automate the movement of these reels.

A damaged headbox apron lip is a common sight on a papermachine and a frequent cause of paper production quality problems.

It depends. If the dryer is running at a high speed (say, 3500 fpm) and the condensate is rimming, there may be no noticeable change in dryer drive power.
