Torque Of Rotary Kiln

The kiln torque is created by gravity acting on the material bed in the kiln. as the kiln rotates, the material bed is not aligned vertically with the kiln axis and this createsorque that opposes kiln rotation. thus, the intensity of the torque reflects the material bed angle inside the kiln. this angle is itself dependant on the stickyness of the material, hence on the amount.

The rotary kiln hasarge starting torque, and the starting is usually performed under full load. at this time, no oil film is formed in the roller bearing, and the resistance torque is also large. generally, the starting torque is 3.54 times the normal torque.
