  • How to Dry Pulverized Coal: A Case Study
    Crushed, pulverized, finely ground coal (-60 mesh) was required for a hydrogenation process. Because certain coals are explosive when dry and finely ground...
  • MEI Case Study - PowerGen - Pulverized Fuel Ash
    Power Gen PLC of Retford, England rely on Macawber engineering at their Cottam Power Station (4x500 MW) to replace an existing fly ash handling system. The Macawber AshVeyor System was installed on unit #2 to continuously convey pulverized fuel ash (P.F.A.) over a distance of 560 feet.
  • Cement Plant Conveys and Weighs
    When replacing coal with an alternative fuel comprised of recycled waste materials, a cement producer chose flexible screw conveyors to convey and weigh pulverized fuel ash to the fuel preparation plant.
  • Modern Methods of Particle Characterization (.pdf)
    Since prehistory man has been aware of the importance of particle size in producing resources and wares with desired properties. Archeological evidence indicates that paints used for cave wall paintings are mixtures of finely pulverized pigmenting materials, predominantly carbon, ochre and hematite
  • Case History: Updating Feeders Improves Jet-Milling Production at Custom Processor
    On a processing line dedicated to a single material, a feeder's cleanout features may not be of concern. But when a custom processor needed to run many different materials, a feeder that could quickly and completely empty its contents was essential. Located in Moorestown, N.J., Jet Pulverizer first
  • Virtual Sensors for Advanced Pharmaceutical Process Control
    explain how they might be applied in pharmaceutical manufacturing. In this case, a virtual sensor was developed from first principle models, and used in the wet grinding circuit of a lead-zinc ore beneficiation plant. In the first step of the process, the ore is pulverized into finely ground
  • Different Approaches to grinding abrasive materials
    crushers. For fine grinding (minus 50 mesh range down to about 95% minus 325 mesh), three different types of machines are employed: ring-roll air swept pulverizers; ball mills; and vibrating mills. For micron and nano-sizing, Custom Processing Services uses spiral jet mills; fluid bed jet mills
  • MC Case Study - BSI Korea - Coal
    down to pulverized particles of less than 0.1mm. The customer selected reliable and robust Macawber Denseveyor TM systems in an explosion proof configuration to handle the requirement of achieving a clean transfer of coal to the bunker with machine reliability and minimal maintenance. Through 30 years
