Photo of the Week: Rotary Dryer Lifter Designs

This week’s photo features two lifter designs. Lifters, also known as fins or flights, are commonly added to the interior of a rotary dryer to assist in the industrial drying

Effect of Lifter Design on Drying Performance in Rotary

The movement of particles in rotary drum dryers depends on the shape of the flight design, [4, 5] rotational speed, drum fill, and particle size. Six modes of particle motion were observed by

Modelling the hold up of lifters in rotary dryers

2009-2-1  This paper presents a new model, GFRLift, which estimates the amount of material that can be supported by the lifters during rotation and compares this for different lifter geometries.While it is recognised that the drying characteristics, and hence the design of a rotary dryer, are dependent on both the volumetric heat transfer coefficient and the dynamic hold up, it is predominantly driven

Effect of Lifter Design on Drying Performance in Rotary

Lifter use in dryers improves mass transfer by increasing the amount of surface area available for transfer and also by increasing the velocity of gas over the particle surface. An even cross-sectional distribution of particles in a dryer improves the efficiency of operation by ensuring that evaporation from falling particles is taking place

Modelling the hold up of lifters in rotary dryers

Rotary dryers contain lifters to lift the material away from the bottom of the dryer and then to drop it through the gas to promote mass and heat transfer between the granular material and the gaseous phase. Understanding these lifters may result in improved dryer design. This paper describes a model that can be used to predict the hold up of

FLIGHT DESIGN FOR ROTARY BAGASSE DRYER

2017-8-16  Lifter B, which is the similar to Lifter A but is inclined at angle has a higher hold up, a larger range but a smaller flux. This reflects that the apex of Lifter B is closer to the dryer wall during rotation so the amount of material lost during a small angle of rotation is smaller than that lost by Lifter A,

Especially in fertilizer and minerals industry for drying products such as coal, clay, gypsum, kaolin, limestone, mineral sand, potash, silica sand etc. Rotary Dryers from SAKA provide controlled, uniform and efficient drying to help you achieve desired product quality.

Theoretical description of the motion of a particle in

In industry, lifter holdup and Mean Residence Time (MRT) are the main rotary dryer design parameters. 13, 14 The lifter holdup represents the volume of material lifted, which is then suspended for an interval of time in the air in the form of particle curtains. The MRT is the mean time taken by the particles to pass through the tube.
