Dec 07, 2018 Generally speaking, direct-fired rotary drum dryers are more efficient that indirect-fired dryers. However, there are advantages to choosing an indirectly heated rotary dryer. The customers can select to use Direct-Fired Rotary Dryer s or Indirect-Fired Rotary Dryers according to the features of raw material and the end use of the dry product.
This is why, at FLSmidth, we have designed and engineered an Indirect Rotary Kiln that aims to provide a solution to these problems. Rather than applying heat directly to the material as direct rotary kilns do the Indirect Rotary Kiln is heated from the outside, where the material is heated

How the Indirect Heat Dryer Works. Materials are fed into a rotary drum that is encased in a stationary refractory lined furnace. This furnace casing has a series of burners mounted down the length of one side firing into the furnace chamber. As the material progresses down the length of the unit, it is subjected to different temperatures in ...
Nov 29, 2015 Indirect heat dryers depend on conduction and radiation to transfer the heat from the cylinder walls to the wet feed. A stationary furnace surrounds the rotary cylinder and heats the cylinder walls. Little or no airflow is required to pass through the dryer. Indirect dryers can provide only a limited amount of heat transfer area.
Indirect rotary dryers. Indirect rotary dryers differ from convective-direct 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.
Vulcan Indirect Rotary Dryers are built to rigorous safety and performance standards because they are 100 designed, manufactured and tested in the USA. Vulcan Indirect Rotary Dryers rely on the heat transferred through the drums shell to dry the material via conduction and radiation to reduce the materials moisture content.
Indirect heating type rotary dryer. This is an indirect heating type of rotary dryer that brings materials into indirect contact with heating medium to provide heat exchanging. The indirect heating type of rotary dryer is classified into external heating rotary dryer and steam tube dryer, which are applied for the following conditions.
ROTARY DRYERS. Louisville Dryer Company offers expertise in construction, service, and maintenance on many types of rotary dryers, including Direct Heat Dryers, Direct Fired Dryers, Indirect Heat Dryers, and Steam Tube Dryers.. Our dryers are built using the latest technologies, in our own state-of-the-art factory, not at sub-contractor facilities.
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 off-gas system is smaller and more economical.
To verify the portability of experimental results for indirect dryers, a drum dryer with indirect electric heating in a laboratory scale was designed and built to test and study the process of indirect drying. Based on the results obtained on a small-scale device, a prototype of a pilot steam-heated rotary dryer was designed and manufactured.

In the case of a rotary dryer, the material is being heated directly by the gases, ie. convection. However, the material is also getting heat from the shell of the rotary dryer through means of conduction. In an indirect fired rotary kiln, conduction is the only source of heat transfer.
Apr 27, 2007 Two different approaches were used to predict the solid moisture content and solid temperature profiles along a continuous indirect contact rotary dryer heated with steam tubes. One of these uses heat and mass balances applied to the solid phase in a differential element of dryer length. Here the heat flux is computed through an overall heat ...

These indirect heat rotary drum dryer are equipped with distinct inlet air temperature and outlet air temperature with centrifugal atomization drying methods for enhanced performance. The best part of buying these efficient indirect heat rotary drum dryer is the after-sales service that involves maintenance and other associated activities.
Direct-heat rotary dryers can operate on fuel oils, natural gas, propane or coal. In addition, steam-heated clean air and flue gases may be used as a heating medium. Indirect-heat rotary dryers are available in steam tube designs and standard rotary models. When the standard rotary design is used, convection heat transfer is employed.
Depending on the product, our specialised engineers will determine the drying air temperature, co or con current systems, burner type and fuel source to suit. If products are sensitive to combustion, indirect heating options are available via can heat exchangers or heating from outside of the shell. Consep is a custom manufacture.

Jul 05, 2020 Direct-heated rotary dryer. 2. Indirect- Direct rotary dryer. 3. Indirect rotary dryer. 4. Special type. A rotary dryer is said to be of the direct type if, by virtue of its design, heat is added to or removed from the solids by direct exchange between the gas and solids. The direct heat dryers are the simplest and the most economical class.
