  • indirect heat transfer dryer problems and solutions services

    Whether you are using a rotarydryer, rotary kiln, or rotary cooler, there is one thing that all these instruments have in common: they all use methods ofheat transferto carry out their jobs.Heat transferis howheatmoves from one source to another. Understanding the types ofheat transfer, and how they differ, is an important part in understanding how a rotarydryer, cooler, or kiln works.

  • Indirect vs. Direct The Heat Transfer Method Does Affect

    Most applications employ steam as anindirectsource, using either aheatexchanger totransfer heatto a gas carrier or a jacketed vessel or drum toheata surface. It also is used as a directheatsource to achieve effective drying. The amount of energy that can be carried by steam is related to the pressure at which the steam is delivered.

  • Indirect Drying vs. Direct Drying FEECO International Inc.

    Conversely,indirect dryersdo not utilize direct contact with process gas to dry the material. In fact, this is the precise advantage of anindirectrotarydryerfor two reasons: It avoids the issue of fine materials becoming entrained in a process gas, which can be aproblemwhen processing fine materials in a directdryer.
