  • Conventional and modified rotary dryer: Comparison of

    9/1/2009· To compare the performance of the conventional cascading rotary dryer with the roto-aerated dryer, an experimental design was elaborated. The variables analyzed were the solids flow rate ( G S ), air velocity ( v f ) and dry air temperature ( T f ) under several levels, chosen by a composed central experimental design with 4 replicates at the center levels, with 18 experiments [7] .

    12/22/2015· Recently, Ajayi and Sheehan (2012b) carried out an intensive literature survey about the design loading determination. They performed experimental work on a horizontal pilot scale rotary dryer with a diameter of 75 cm and a length of 115 cm fitted internally with angular flights. The design loading experiments involved two methods for the image analysis of multiple photographs of the cross sectional area of the solids in the front end of the dryer

  • Advanced control of a rotary dryer University of Oulu

    The aim of this research was to improve dryer control by developing new hybrid control systems, one consisting of a fuzzy logic controller (FLC) and PI controller and the other of a three-layer neural network (NN) and PI controller. The FLC and NN act as supervisory controllers giving set points for the PI controllers. The performance of each

  • A study of particle motion in rotary dryer

    Perry and Green (1999) suggest that the volume occupied by the load of solids in the rotary dryer should be between 10 and 15% of the total dryer volume. Figure 2 presents a scheme of the flights with two segments, indicating the main dimensions and variables that will be used in the equationing accomplished in this work.

    The experimental data were obtained by Arruda (2008) with a conventional rotary dryer equipped with three-segmented angular flights. The flights had the dimensions: first segment = 0.02 m, second and third segment = 0.007 m; the length of the flights was 1.5 m, with an angle of 135º between segments.

  • PERFORMANCE EVALUATION OF A LABORATORY SCALE SPRAY DRYER

    Baker and McKenzie. (2002) made a survey, which included dryers having evaporation rates ranging from 0.1-12 t/h. Values of the specific energy consumption (Es) varied widely, ranging from less than 3 to around 20 GJ/t of evaporated water; the average for all dryers included in the survey was 4.87 GJ/t.
