WHY FLIGHT DESIGN MATTERS Flights also known as material lifters are a key component in the performance of rotary dryers and coolers As the unit rotates flights pick up the material carry it higher and drop it through the air stream creating what is referred to

dryer to the other In direct heat rotary dryers a hot gas flowing through the dryer provides the heat required for vaporization of the water To promote gassolid contact most direct heat dryers have flights see Figure 1 placed parallel along the length of the shell which lift solids and make them rain across the dryer section The

Our Single Pass Dryer System are built with robust and high temperature resistance material We customized fight designs lift the product and cascade it through the heated gas stream Our internal designs provide maximum production and assured moisture control

Holdup in the flights rotary dryers can be classified according to its loading state as either over under or at design load For a angled hook flight the range of the discharge angle increases leading to a more uniform cascade pattern in time and an enlarging of the area occupied by the curtains of particles

Nov 26 2001 · Abstract Rotary dryers for particulate solids commonly use flights along the length of the shell to lift solids and make them rain across the dryer section These flights are critical to dryer performance

Apr 27 2007 · ABSTRACT In designing cascading rotary dryers it is important to size the flights correctly in order to ensure that they can adequately accommodate the contents of the drum A set of equations has been derived to calculate the solids holdup on angular and extendedcircular flights in such dryers

Jan 28 1992The rotary drum dryer includes a plurality of circumferentially spaced flights in each of a plurality of axially spaced flight sections A radially inwardly directed dam is interposed between each flight section and serves as a pivotal mount for the flights of each section

Determining Flight Design Through Testing The combination of optimal flight design and pattern is often determined through testing in a facility such as the FEECO Innovation Center In addition to the Innovation Centers pilotscale rotary dryer process engineers often enlist the help of the facilitys flight

flights segments changes the flight loading and thus the material holdup which leads to different discharging profiles of the flight Holdup in the flights rotary dryers can be classified according to its loading state as either over under or at design load For a angled hook flight the range of the

rotary dryer fight design Rotary dryers are a class of dryer commonly used in industry to dry particulate solids Keey 1972 They are made of a long cylindrical shell that is rotated The shell is usually slightly inclined to the horizontal to induce solids flow from one end of the dryer to the other In direct heat rotary dryers

Nov 26 2001· In direct heat rotary dryers a hot gas flowing through the dryer provides the heat required for the vaporization of the water To promote gas–solid contact most direct heat dryers have flights placed parallel along the length of the shell which lift solids and make them rain across the section of the dryer Fig 1
