    https://powderprocess.net

    www.PowderProcess.net is a free online handbook giving explanations, design methods and operational tips on the most common unit operations and equipment found in Industries processing powders. It gives materials for Engineers who, around the world, have to design, operate or troubleshoot a powder handling process.
    • Conveying Speed / Velocity

      With : - u air = air velocity in conveying pipe of diameter D (m/s) - Q air = air volumetric flow rate (m 3 /s) - D = pipe diameter (m) Note the following : the air volumetric flowrate is changing with the pressure and temperature, along the conveying line pressure is decreasing thus air expands, which makes the volumetric flowrate higher and thus the conveying air velocity higher (at constant D).

    • FIBC and IBC

      This page will 1st focus on FIBC which have taken a very important place in the powder handling systems of manufacturing facilities since 20-30 years, then on IBC which have enjoyed a strong regain of interest recently as they can allow good dust containment. ... of maximal load and number of use must be strictly followed in order to ensure ...

    • Bad Flow, No Flow

      If the design by itself cannot ensure a free flow, or if it is necessary to improve the flow of powder after installation, the use of discharging aids should be considered. The following paragraph discusses the most common discharging aids used in powder handling industries. 3.

    • Airlock Rotary Valve

      An airlock rotary valve is a mechanical conveying device that allows to control a bulk solids flow (powder, pellets, granules ...). Such airlock feeders (also called rotary valve feeder or star valve) are often used prior to a pneumatic transport system. ... Continuous operation Simple (but rough) throughphut adjustment if motor on VFD Low ...

    • V Blenders

      Figure 1 : V blender drawing. 4. Mixing operating parameters. For V mixers, the mixing time is typically 10-15 min. Common problems leading to a long mixing time or not achieving the right Cv Homogeneity is an overfilling of the blender or using materials that are not free flowing enough, or free flowing but with large particles / density differences.

    • Design Methods Dense Phase

      1. Method and limitations How to design and size a dense phase pneumatic transport line ? There are few existing methods published to calculate dense phase pneumatic conveying system s but most of the knowledge here stays with specialized suppliers. Anyway, if dilute phase pneumatic conveying lines can be sized pretty confidently thanks to models, it is less true for dense phase conveying ...
