The two experimental methods presented here can be used to quantify powder self-heating hazards in layer and bulk conditions in industrial processes Bulk storage of heated powders and powder accumulations on hot surfaces or in heated environments can potentially lead…
The advantages and limitations of three powder-testing techniques are reviewed here Powder testing is deployed to characterize products including pharmaceuticals, foods, metal powders, powder coatings and cement — at every stage of the product lifecycle. The resulting data-support product development…
Drying is a demanding unit operation where solvents need to be removed without altering product chemistry. Vacuum dryers are essential pieces of equipment for accomplishing this task Drying solids is a demanding task that requires both knowledge of process technology…
Precise control over spray-drying processes can be enabled by modern measurement approaches that provide information on particle size and shape in realtime The process of spray drying is extremely valuable to a wide range of solid-product manufacturers due to its…
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…
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).…
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…
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…
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…
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.
