Rotary dryers work by tumbling material in a rotating drum in the presence of a drying air. They can also be indirectly heated to avoid direct contact between the material and processing medium. The drum is positioned at a slight horizontal slope to allow gravity to assist in moving material through the drum.
6. The dryer adopts aligning roller device, so that the roller and rolling ring are always in linear contact, thereby greatly reducing the wear and power loss. As the experienced rotary dryer manufacturer, Hongxing Machinery has high quality rotary dryer for sale, and the rotary dryer
The rotary dryer is a piece of equipment which is of relatively common use in the chemical process industries, due to its simplicity and versatility in handling different types of solids. The ability to estimate its operating characteristics is of major importance either in the production planning of an existing plant or in the design of a new one.
In general, there are limited applications for these dryers. For the drying of liquids or liquid suspensions, the evaporator of choice is usually either a drum dryer or a spray dryer. A typical film drum dryer with a 4 ft 1.2 m by 10 ft 3 m long drum will evaporate about 600 lbh 270 kgh of water.

Clearly, no single design procedure that can apply to all or even several of the dryer variants is possible. It is therefore essential to revert to the fundamentals of heat, mass and momentum transfer coupled with a knowledge of the material properties quality when attempting design of a dryer or analysis of an existing dryer.
dryers with a bottom row of cylinders serving merely as turning rolls. Thus, the web is continuously supported by a fabric there are no free draws. However, only one side of the paper is heated, and therefore a section with dryers on the bottom row are inserted in the dryer, a shown in Figure 15.

Most of the drying takes place while the material falls through the air blast. Using very hot air or combustion gases, rotary dryers can also function as roasters for nuts, sesame seeds, and cocoa beans. A detailed method for the design of rotary dryers, based on a heat exchange approach has been described by Nonhebel 1971.
