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

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 rotary driers often use steam as a heating medium. These types of dryer are prevalent in the oil seed, chocolate and pulp industries (to name a few). Process. Material is gravity fed into the dryer at a constant rate. Flights mounted to the interior of the dryer shell have two purposes

Depending on the type of system in use, heat transfers to or from a material differently. 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

Jul 05, 2020 Based on the method of heat transfer, rotary dryers can be classified into; 1. 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

Jun 11, 2015 Indirect heat drying is most frequently used for products with small particle sizes that could result in excessive dust generation. The frac sand industry utilizes both types of dryers. Rotary dryers are the more expensive of the two, but they are more forgiving and allow greater process turndown capability

Oct 02, 2020 Rotary drums can also be used in niche applications as an indirect heat transfer mechanism. This works especially well with fine, lightweight materials or highly combustible materials. The indirect heat transfer process relies on the heat from the drum’s shell to dry or heat the material through conduction and radiation

Nov 29, 2015 Indirect heat rotary dryers are most frequently used for products with small particle sizes that could result in excessive dust generation. They are also used for processes that require extreme control of the dryer exhaust. Indirect heat dryers depend on conduction and radiation to transfer the heat from the cylinder walls to the wet feed
