Hot sale rotary kiln for Kaolin and bentonite calcination

详情

Introduction: Rotary kiln is the Thermal Equipment for heating materials, widely used in cement industry for clinker calcinations. It is also used in various industries, such as cement, nonferrous metallurgy, ferrous metallurgy, chemistry, building, refractory material, environmental protection, etc.     
 
Rotary kiln is composed of cylinder, gears, support device, kiln liner and kiln tail sealing equipment, kiln head hood and combustion. Cylinder as heated pivoting part made of high-quality carbon steel plate.  
 
Working principle:
The kiln is a cylindrical vessel, inclined slightly to the horizontal, which is rotated slowly about its axis. The material to be processed is fed into the upper end of the cylinder. As the kiln rotates, material gradually moves down towards the lower end, and may undergo a certain amount of stirring and mixing. Hot gases pass along the kiln, sometimes in the same direction as the process material (co-current), but usually in the opposite direction (counter-current). The hot gases may be generated in an external furnace, or may be generated by a flame inside the kiln. Such a flame is projected from a burner-pipe (or "firing pipe") which acts like a large bunsen burner. The fuel for this may be gas, oil or pulverized coal
