Particle Impact Problems in Pneumatic Conveying
Pneumatically conveyed solid materials inevitably impact pipe walls and other particles, which can create processing and equipment problems. Provided here is an outline of potential problems related to particle impacts and the physics behind them Among the defining features of…
Advances in Pin Mill Technology
Improvements provide finer grinding at lower energy costs compared to air-swept classifying mills that have long reigned supreme in particle-size-reduction efforts For decades, the ultimate performance in fine mechanical milling performance has been provided by the air-swept classifying mill (ASCM).…
Emerging Applications for Traditional Dryers
Traditional classes of drying equipment are being adapted for use in a growing number of applications, and more complex analysis and process control are helping to optimize processes The chemical process industries (CPI) are full of processes in which a…
The Benefits Of Two-Stage Drying
Circular fluidized-bed dryers can boost the capacity, energy efficiency and product quality when used in conjunction with other primary dryers Two-stage drying provides benefits from the standpoints of cost, energy savings, efficiency and product quality. This is especially the case…
Feeding and Conveying: Keeping Solids Moving
Updated feeding and conveying products help improve product flow When it comes to feeding and conveying operations, chemical processors struggle to minimize unplanned downtime and maximize throughput. For this reason, they require reliable equipment that is easy to clean in…
Hear how quiet a vacuum pump can be…
VACUUBRAND's chemical-resistant diaphragm pumps have been designed and manufactured to exacting standards not only in order to achieve the performance our customers count on, but also to run quietly.
Characterize Bulk Solids to Ensure Smooth Flow
To minimize problems associated with handling all types of bulk solids, engineers must adopt a systematic approach to characterizing the flow and mechanical properties of the materials under a variety of operating conditions Bins, hoppers, feeders, and conveyors handle bulk…
Particle-sizing technology selection
Size range is a defining consideration when it comes to choosing a particle-sizing technology for your product or process. However, whether measuring droplets or powders, on plant or in the laboratory, for quality control (QC) or to troubleshoot – there…
Hopper Design Principles
When hoppers are designed without consideration of the actual materials being handled, problems inevitably arise. Follow this guidance to avoid common solids-handling issues, such as erratic flow and no flow Pivotal work on the development of the theory of bulk…
Combustible Dust Standard Gets a Facelift
While NFPA 652 creates a general set of requirements for mitigating explosion hazards, equipment providers improve offerings to assist with compliance The National Fire Protection Association (NFPA; Washington, D.C.; www.nfpa.prg) recently released the first edition of NFPA 652 Standard on…
