Facts at your Fingertips: Centrifuge Separation Capacity

This one-page reference describes how to measure the capability of a given centrifuge to separate solids from a liquid phase. G-force The centrifugal force developed by a centrifuge is expressed as a multiple of the force of gravity. This force,…

Facts at your Fingertips: Removal of Particulate Matter from Industrial Processes

Controlling and reducing particulate matter pollution from industrial operations is a key environmental and human health objective. In chemical process industries (CPI) facilities, airborne particulate matter can result from combustion of fuels, or from process operations, such as dust from…

Facts at your Fingertips: Agglomeration Processes

Agglomeration converts fine powder particles into larger ones by introducing external forces. Major benefits for solids processors include dust reduction, easier handling, more complete utilization of raw materials and densification. Agglomerating particles happens by a variety of means, including mixing…

Facts at your Fingertips: Pneumatic Conveying Challenges

Among the key benefits offered by pneumatically conveying bulk solids is the ability to route materials around obstructions in the plant using bends in the pipeline. However, these changes in direction involve a considerable number of particle impacts on the…
