In a direct-fired rotary kiln, the heat source is hot gas (products of combustion and air), which flows with an inherent velocity. These gases can carry particles through form drag. The degree of entrainment depends on a variety of factors, such as gas velocity, gas density, particle density, and shape

Rotary Kiln Dryer Types. Direct Heating Type: this type of dryer is permissible for hot gas to direct contact with raw materials, with high efficiency and good drying effect. Indirect Heating Type: the indirect heating dryer is applied when the hot gas has a harmful effect on raw materials, the drying gas will not direct contact with materials. It is less efficient compared with the direct heating rotary dryer but can realize …

simulating the granular materials flow in rotary kilns

Granular materials flow is discussed by different models. These models are 2D and each of them includes some special effects of two phase flow. For simulating the 3D flow of granular materials in rotary kilns, a model based on finite volume method (FVM) is presented which includes axial and rotational motion and also all of the effects of two phase flow such as: viscosity effect, particle size

Aug 24, 2015 · 9 Rotary Kiln Processes: With the arrival of rotary kilns, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a powder or "raw meal"
