The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer. Based on the configuration, rotary dryers can be classified as co-current, counter current, direct fired and indirect fired. Explanation of each configuration is given below: Unique Features
Indirect-fired rotary kilns (furnaces) Rotary kilns (furnaces) of indirect heating are used for drying different friable materials as well as heating them up to temperatures required for different technological processes. In rotary kilns of indirect heating processes of heat production take place outside the case of the rotating furnace.
Rotary kilns come in two different types: Direct fired rotary kilns — Consist of a steel shell lined with a protective brick or castable lining to withstand extreme temperatures. Indirect rotary kilns — Unlined kilns with shells made from a temperature-resistant alloy rather than steel. Rotary Dryers
Louisville Dryer Company provides both refractory lined Direct Fired Kilns and Indirect Heat Kilns for the purpose of low-temperature incineration and gasification of …
Nov 04, 2015· Indirect-Fired Dryers Conversely, indirect-fired rotary dryers avoid direct contact between the material and the drying air. 10. Instead, the dryer shell is heated from the outside, and the material is dried through direct contact with the heated shell.
Industrial dryers are used to remove moisture from a product. They operate under different pressures and temperatures depending on the material and process used and …
Indirect Heated Fired Rotary Dryers. Indirect Heated Fired Rotary Dryers are commonly used for carbon black pellets drying. Carbon black coming from the reactor, which is not part of Idreco technology, is fed to a wet pelletizer where water together with molasses are added to form wet pellets.
Nov 02, 2018· An example of a Vulcan Drying System completed indirect dryer for a satisfied client. This unit was designed for precious metal extraction. For more informat...
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.
Indirect rotary dryer. 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. They are used when direct contact with the hot gas or air is not ...
Direct and indirect-fired rotary dryers are used in a variety of industrial settings to dry bulk solids. While the two are both comprised of a rotating drum and function to reduce a material’s moisture, several differences between direct and indirect dryers exist:
A direct fired dryer operates in one of two modes: co-current, or counter-current. In either of the above arrangements, the operation of a direct fired rotary dryer is based on the combustion system (burner) being directly coupled to the rotating shell.

Vulcan Drying Systems Indirect Fired Rotary Dryer IDR 9640 Series. Manufacturer: Vulcan Drying Systems; Vulcan Drying Systems Indirect Rotary Dryers rely on the heat transferred through the drum’s shell to dry the material via conduction and radiation to reduce the material’s moisture content. Indirect …
Indirect Rotary Dryers. Unlike direct dryers, indirect dryers do not rely on direct contact between the material and process gas to dry the material. Instead, the rotating drum is enclosed in a furnace, which is externally heated. Contact with the heated drum shell is what dries the material.
If it is not possible to apply heat direct to the material to be dried, Rotary Dryers of the Indirect Heating Design can be furnished so that the heated gases will not come in direct contact with the material. Sizing a Rotary Dryer using a Capacity Table Rotary Dryer is a simple, inexpensive unit for reducing the moisture content of flotation ...

INDIRECT FIRED ROTARY CALCINER OR DRYER. CONSULTING. RMF Enterprises provides diagnostic consulting services to identify the issues with your indirect fired rotary calciner. Phone support is available to diagnose the problem with your calciner, identify and purchase spare parts, and to ensure proper rotary calciner alignment. ...
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.
Indirect-fired rotary dryers are better suited for niche applications. Indirect-fired dryers are ideal for processing dusty, fine materials, or materials that cannot be exposed to oxygen or combustion gases during processing. This is commonly seen with food grade materials, highly combustible materials, organics such as grains and pulps, and ...
Rotary Dryer Design & Working Principle
These types of materials are easily aspirated from, or degraded in, a conventional direct fired, or direct heat dryer, therefore leaving little time to be brought up to temperature. The Louisville Dryer Indirect Heat Dryer provides the perfect tool to accomplish each of these tasks as effectively as possible.
