Adjustment of rotary kiln rollers
In order to ensure the long-term safe operation of the rotary kiln, in the process of rotary kiln operation, in the mechanical maintenance of the primary task is to maintain the kiln body "straight and round" and the stability of the axial fluctuation, and to complete the above task is one of the most important work, is to correctly adjust the pallet.
In order to ensure the long-term safe operation of the rotary kiln, in the process of rotary kiln operation, in the mechanical maintenance of the primary task is to maintain the kiln body "straight and round" and the stability of the axial fluctuation, and to complete the above task is one of the most important work, is to correctly adjust the pallet.
Adjustment of the basic principles of the pallet:
(1) adjust the wheel so that the center line of the kiln body is a straight line rotary kiln kiln body is supported by the wheel belt in the multi-block wheel, in the case of supporting parts size is unchanged, the position of the kiln body is subject to the position of the wheel to determine. Rotary kiln in the process of use, we must often adjust the position of the pallet to ensure that the kiln centerline is a straight line.
(2) Adjustment of pallet to make the kiln body normal traveling, rotary kiln in operation, in order to make the pallet and belt surface wear uniform, should make the kiln body in the upper and lower baffle wheel between the constant axial fluctuation (known as traveling).
In order to achieve the above requirements, the center line of each carrier wheel should be skewed at a small angle, so that the carrier wheel in the rotation process, to produce an upward thrust on the kiln body to overcome the kiln body's downward sliding, and make the kiln body slowly upward scurrying, when the kiln body reaches the upper baffle wheel position, the surface of the carrier wheel can be added to the appropriate amount of lubricating oil, reduce the friction coefficient between the surface of the carrier wheel and the wheel belt, so that the carrier wheel's upward thrust decreases, and the kiln body relies on the Its downward force slowly downward movement; when the kiln body to reach the position of the lower block wheel, the lubrication of the surface of the wheel is not, the kiln body and began to move upward, that is, to carry out another cycle of movement, which is called the artificial movement method. With artificial swimming method, pay attention to the control of the kiln body swimming speed. If the kiln body swimming speed is too fast, it increases the contact surface of the belt and the wheel, ring and pinion contact surface of the relative sliding, in contact with the surface will produce skid marks. Generally control the rotary kiln in each shift to swim once appropriate.
