Main function

Rotary kiln is composed of drum, driving unit, support unit, end seal unit, end shield and fuel unit. The shell fabricated from high-quality steel plate is supported on the supporting device of sliding bearing or rolling bearing. Mechanical or hydraulic thrust roller is installed on the support unit to control axial moving. The driving unit makes the drum rotate through the girth gear in the middle of the drum. To meet the need of installation and maintenance, the bigger kiln have auxiliary driving unit. The ends of kiln are provided with sealing unit to prevent cool air into the kiln and fuel dust out of kiln.
