The rotary dryer design consists principally of a rotating cylinder that is enclosed in a furnace along its active length. With heat transfer indirect and through the cylinder wall the gas velocities within an indirect dryer are low as compared to a direct heat dryer and correspondingly the offgas system is smaller and more economical.
Indirect rotary dryer designs are used for fine and ultrafine material especially when entrainment is an issue. Industrial rotary dryers are utilized to process both end products and prepare material for further processing. They offer numerous advantages during for bulk processing of material. While their basic makeup is standardized rotary

The indirect dryer offer higher energy efficiency as compared to direct dryer. Being closed loop the vapor produced while drying are also utilized to increase the temperature. Indirect dryers need
TodayFurther single shell rotary dryers hold nearly 2/3 market share as far as drum design is concerned thereby augmenting overall market expansion. The global market is fragmented in nature owing to multiple regional manufacturers across East Asia South Asia and Europe. Increasing penetration of regional players may hinder the equilibrium of
Model integration by taking account of experimental amount of evaporation at dryer exit and temperature profiles along the dryer length has been utilized in the validation of drying kinetics and heat transfer correlations. Model predictions compare satisfactorily with the operating data of an indirect heat industrial lignite dryer.
Rotary Dryers Rotary dryers potentially represent the oldest continuous and undoubtedly the most common high volume dryer used in industry and it has evolved more adaptations of the technology than any other dryer classification. All rotary dryers have the feed materials passing through a rotating cylinder termed a drum. It is
The rotary dryer also known as rotary drum dryer is a kind of industrial dryer that can dry high humidity moisture materials by direct or indirect heating It is a tilted or horizontal and rotating cylinder Rotary drum dryer occupies a very important position in the chemical agricultural coal building materials and light industrial industries.

Indirect rotary dryers. Indirect rotary dryers differ from convectivedirect dryers in that heat is transferred to the wet product by conduction and radiation through the cylinder wall or through a series of tubes located circumferentially to the cylinder. Indirect rotary dryers use as heating medium hot gases coming from a combustion chamber.
Choose an indirect rotary dryer if you are drying highly combustible materials organics such as grain and pulp and fine materials such as pigments.

Rotary Dryers are used across a range of industries to reduce the moisture content of a variety of materials from biomass to mineral ores. Ansac s Rotary Dryer benefits from all of same design efficiencies that our Rotary Kiln does including high thermal efficiency low fuel consumption and a reduced footprint but has a series of unique features that differentiate this dryer from its
Indirect dryers are enshrouded in a furnace which externally heats the drum to avoid direct contact between the heating medium and the material being dried. Evaluate for Proper Air Flow. When working with a direct configuration the air flow configuration is another major decision in the rotary dryer design process.
Step 3 Choose Your Options. Vulcan® s Indirect Rotary Dryers come in standard sizes ranging from 3 diameter by 15 long to 8 diameter by 60 long. Whether you have a small 1TPH project or a large 200TPH project we can construct your dryer to fit your project. Standard Dimensions
If it is not suitable to apply heat direct to heat and dry the raw material then rotary dryers of indirect heating design can be furnished so that the heated hot gases will not come in direct contact with the wet raw material.
