The load withstood by the cylinder of the rotary kiln includes the self weight of the cylinder, the pressure of the liner of the kiln which is caused by the liner of the kiln, the skin of the kiln and the materials, and the support reaction force of the rolling ring Mobile Jaw Crusher . The cylinder of the rotary kiln is a drum with thin wall, which is supported on the riding wheel. There are refractory bricks in the cylinder. The rolling ring is looped on the cylinder. There are 24 to 42 pieces of pads for the cylinder of the rotary kiln. The pads are wide. The total arc length of the contact between the rolling ring and the pad accounts for about 70% of the entire circumference. As a result, the part between the rolling ring and the cylinder can be approximated as a continuous contact Gold Ore Processing Plant . For the contact between the rolling ring and the cylinder, we should mainly pay much attention to the followings. First, the deformation of the cylinder can cause the looseness of the refractory bricks. The second is the crack of the weld gap, which is mainly related to the bending stress of the barrel. The third is the wear of the cylinder and so on.
As a result, the study on the contact between the rolling ring and the cylinder mainly includes the size of the contact angle between the rolling ring and the cylinder and the distribution form of the contact pressure, which can pave the way for the study on the stress and the deformation of the rolling ring Sand Screening Plant . The study on the gap between the rolling ring and the cylinder can help us to find the rules of the changes of the bending of the cylinder and the bending stress, which can avoid the red kiln accidents caused by the deformation of the loosening of the refractory bricks. The attrition of the cylinder at the contact position is mainly the micro sliding attrition. Therefore, grasping the distribution rule of the contact pressure at this position can help us to reduce the attrition.
