Conmark Agitators and Mixers

Too often, the paper and pulp industry unnecessarily consumes too much energy  in the blending processes. Conmark's technology offers not only the most energy efficient impeller design available, but Conmark also provides the technical expertise necessary for calibrating each agitator properly for the specific application.

Bad agitation is a major source of variability in current Pulp and Paper Processes. Conmark Agitators can drastically improve this problem. If a pulp and water mixture is allowed to stand in a chest for just a short period of time, the fiber and water mixture will begin to separate. When this occurs, the chest content is composed of irregular high consistency zones that cannot easily be re-introduced to the papermaking process. These stock irregularities create consistency variations.

Agitation in a stock chest is the only way to keep the stock from dewatering. With good agitation and good consistency control, it is possible to re-introduce a uniform stock back to the process. When this process was first installed in the mill, the agitators were configured for the process conditions at that time. Yet since initial set-up, many changes may have been made to the process that may have made the agitator performance inadequate for the current process conditions. 

​It is necessary to analyze the performance of the agitators to understand it's effects on end product quality. An undersized agitator inadequately agitates a stock chest and does not improve the uniformity of the stock and may actually increase consistency variability. Even when a consistency control loop is present downstream from the chest, the chest variations may exceed the capability of the consistency control loop. As a result more consistency variability is introduced into the stock.

If variations are present in the stock out of a chest, a careful analysis of each agitator's performance is necessary. Yet the opportunity to reduce process variations exists today with good solutions to agitator probems. Conmark's Mixers and Agitators are a unique solution that can be retro-fitted to your existing installations. It's constant pitch technology provides increased mixing at lower horsepower consumption reducing energy consumption and eliminating variability from your process.
