The salt quality was studied by dewatering methods such as centrifugal hydro extraction, fixed bed dryer, and rotary drum dryer. effect of different particle sizes also analyzed. extractor is found to be effective when reducing the high-water content suitable for water after wash stage. Fixed dryers produce lower than dryers. A 1% can achieved using Finally, all extractors, dryers, are producti...

The influence of different internal geometries on the solid flow in rotary drums under variation operational parameters feed rate, slope, and rotational speed is investigated. Four configurations a fully optically accessible lab-scale drum are analyzed. internals built as sectional compartments cross section, referring to industrial applications. axial dispersion model used calculate mean resid...

Rapidly growing aerobic organisms can deplete oxygen in the nutrient medium even when culture vessels are open to the air. Agitation is beneficial under these conditions because it tends to expose more liquid to the air, and because the mixing tends to make conditions more homogeneous throughout the volume of the medium. Rotary and reciprocating shakers are capable of high rates of aeration whe...

The drying is a basic operation of enormous commercial importance in all industrial applications ranging through the food, agricultural, mining and even manufacturing sectors [1]. Modern societies need better product quality, enhanced safety practices and more environmentally benign operations as well as higher productivity, better energy yield and reduced material wastage, also [2]. As drying ...

Researching the moving speed of particles in a drum is helpful to optimal design rotating device. In this paper, average mixing velocity flake with different shapes an elliptical studied. detail, systems rectangular, triangular, and circular are studied; rollers eccentricities periodic variation characteristics particle system at 15 rpm 45 compared analyzed; curves velocity, peak fitting curve ...

Abstract Rotary drums equipped with longitudinal flights are mainly used to dry granular solids and handle high throughputs. The design of the is a crucial task because they decisively influence distribution particles over dryer cross section. In previous work, authors derived mathematical model for particle flow in rotary rectangular flights. this model, final discharge angle was underpredicte...
