Valmet polarized forming fabrics give great results, case studies

Customer experiences have shown that Valmet's polarized forming fabrics have the potential to revolutionize water removal in the papermaking process. Two board machine case studies illustrate the savings that are possible.

Increase drying capacity with a Valmet Air Dryer Nozzle Upgrade

Existing single- or double-sided air dryers with inefficient nozzles can be upgraded by installing the patented Valmet Air Dryer Nozzle Upgrade - without changing your dryer layout. Up to a 50% drying capacity increase can be realized.

Using wood powder as fuel in lime kilns, pilot case study

A Valmet white paper discusses the use of wood powder as a replacement lime kiln fuel, as well as the factors that must be considered when evaluating using wood powder as kiln fuel and the lessons learned from operating with wood powder. Södra has contributed to this paper based on their experience at Södra Värö mill with a wood powder firing system that was installed in 2014.

Web handling - The poor man's spreader or bow-tie roller

Straight shaft rollers can be used as spreader rolls. They are called "Bowtie" rollers because a concave crown is machined into the roller.

Your one-stop shop for control valves

What do you look for in a control valve supplier? When it comes to control valve requirements no two are ever the same. It is not just the pressure and temperature of the process or the required controllability, but also issues such as the need to prevent cavitation, to control noise, to keep within emission limits, etc. This means selecting a control valve always requires due care and attention.

Controlling your flotation process

Flotation is an important part of mineral processing in most mining operations, requiring an accurate, durable, and repeatable level control valve to manage level control in the column, cell, staged reactor, or direct reactor. The head pressure to the control valve from each type of flotation process makes sizing a critical function to ensure proper operation of the valve and performance of the solution. For instance, flotation cells have very low driving head pressure to the valve. Since the head pressure is so low, inlet velocities, outlet velocities, and any bends or elbows in the piping can affect this low head pressure. If all factors are not considered carefully in this case, the danger is mis-sizing the level control valve on the low side.
