Milling is commonly used for particle-size reduction and control of particle-size distribution (PSD) for crystalline solids. Mills are effective for generating consistent solids properties, through size reduction and surface-modification mechanisms [1]. This one-page reference outlines the mechanical forces involved in…
Optimizing electrical conductivity in next-generation batteries depends on carefully controlling process variables, such as mixing, particle-size distribution and temperature. Presented here is a discussion of how these process variables affect battery performance In the evolving landscape of energy storage technologies,…
Metso (Espoo, Finland; www.metso.com) has signed an agreement to acquire Diamond Z and Screen Machine Industries from Crane Group (Columbus, Ohio; www.cranegroup.com), a family-owned investment company. Diamond Z increases Metso’s offering in mobile equipment for the organic recycling markets. Screen…
Equipment innovations and monitoring solutions help chemical processors create more effective dust collection systems Uncontrolled dust can lead to several complications, including health and safety concerns, product quality problems, regulatory compliance issues and legal ramifications. Although dust should not be…
Three of the critical aspects of dust collection systems are properly identifying necessary dust capture points, effectively capturing dust at each point and accounting for solids loading in the ductwork. Key considerations for these aspects are presented here Dust collection…
Understanding material characteristics is important in designing and defining process criteria for optimal performance of rotary and fluidized-bed dryers The ability to efficiently, reliably and consistently dry bulk solids in an industrial setting relies largely on tailoring the dryer’s design…
Particle size and shape, as well as particle size distribution (PSD) are key determinants of bulk solids behavior [1–4]. A particle can be defined as a single unit of material having discrete physical boundaries that define its size. Particle science…
When considering the use of a silo discharge system to help convey materials, it is crucial to assess the specific requirements of the materials being stored, the operational goals and the overall system compatibility Storing and handling dry bulk powders…
A guide to the practical considerations of calibrating weighing instruments is presented here Throughout the chemical process industries (CPI), weighing instruments find a range of important uses and are often a critical piece of equipment for many processes. Monitoring feed…
Energy recovery in spray-drying processes can reduce production costs, but involves trade-offs. Using milk powder as an example, this article describes a spreadsheet method to evaluate exhaust-gas recirculation scenarios for optimizing spray drying Dairy processing is among the most energy…
