This white paper article explains how the compact, inexpensive iris valve can gently control the gravity-flow discharge of many free-flowing materials in dry bulk solids handling applications. This article explains how the iris valve operates, how it can and cannot be applied, what construction materials are available for valve components, and the valve's pros and cons.

The cement is pneumatically conveyed to the top of the silos. The valves on top of these silos are normally opened or closed periodically. However when they require the valves to open or close, it is necessary for them to be able to do so without trouble and they need to be assured that the valve will close tightly. The reason they require these valves to close tightly is that in many cement ...

INTRODUCTION - Helical rotor turbine flow meters outperform flat-bladed rotors by extending the linear range of the flow meter. Manufacturers who produce flat-bladed rotors do so for economic reasons, at the sacrifice of performance. In addition, the helical blade profile transfers energy more efficiently, reducing bearing wear and pressure drop and their associated cost.

The Glen Walter Sewage Collection System was built to service 1080 customers in 1989. At the time the population was 850 but by 1995 the sewage treatment plant had already reached capacity. Shawn Killoran took over the Operations Manger position in 1999 and, along with the Mayor and Council, he immediately had concerns about the excess flow.
The Township started by video taping all of the lines ...

Vapour containment can be one of the most troublesome challenges in operating and maintaining process machinery. Aromatic hydrocarbons are a process ingredient for a vast array of materials, and evaporative loss of these volatile chemicals can be costly in many ways.
The simplest case is that evaporative loss is a direct expense: solvent lost to the atmosphere must be replaced – often at about ...
