Accurate measurements of exposures to aerosols and dusts by plant personnel can be tricky. Here is some help for determining exposures and addressing uncertainties Uncontrolled aerosols (defined as suspensions of fine solid or liquid particles in gaseous media) in the…
Material- and energy-balance models can help to identify potential opportunities The processing of mined minerals in aboveground facilities relies on several energy- intensive unit operations, such as comminution, screening and material transport. Crushing operations typically produce a wide distribution of…
Despite their apparent simplicity, the complexity of these conveying systems demands proper design and an understanding of the underlying principles Screw conveyors play a major role in a wide variety of industrial operations that involve the handling of bulk solids.…
Using flowsheet simulation to model processes involving granular solids — either those that are entirely separate from fluid processes or those that are combined with them — has many advantages for improving the process design. These include avoiding unplanned downtime,…
