The contribution of the rotary kiln pad to the equipment is immense.
The contribution of the rotary kiln pad to the equipment is immense. It can transfer the load of the rotary kiln shell to the roller ring so that the cylinder does not directly contact with the roller ring, so that the space between the pads increases the roller ring. The cooling area ensures that the rotary kiln equipment will work more safely and efficiently. What are the precautions for using the rotary kiln pad? The well-known rotary kiln manufacturer ZK CORP will introduce you to the considerations of using the rotary kiln pad in use.
For the rotary kiln pad, the default rule in the industry is that the number of pads is 300 to 400 mm, the width of the pad is 60% to 70% of the entire cylinder circumference, and the thickness of the pad is 30 to 60 mm. Rotary kiln pad must pay attention to two aspects in the process of use, the following is a specific analysis.
First, the rotary kiln pad and the cylinder of the fixed problem
The newly-manufactured thick support section and the backing plate are generally welded and fixed. The advantage is that the backing plate can be machined after welding, and the installation is convenient. The control of the clearance is more accurate. However, as the backing plate transfers the great pressure between the rotary kiln shell body and the rolling ring and the axial force of the cylindrical body, if the backing plate is all welded with the cylindrical body, a large stress will be generated in the weld, causing the backing plate and the cylinder body. Cracking, often after repeated cracking repair welding, easy to produce welding stress. Therefore, during the repair process of the rotary kiln, the backing plate is preferably not welded to the cylinder body.
Second, the rotary kiln plate wear problem
When the gap between the roller and the backing plate is too large, the two slide relatively large and the contact surface wears too much. The higher the rotation speed of the rotary kiln, the faster the wear. For this reason, when the gap between the roller and the hot plate is too large, repairs must be carried out, and the pads must be replaced or added to maintain proper clearance. The gap between the two can not be less than the design gap (based on the size of the rotary kiln body, generally 4 ~ 10mm), but can not be greater than 20mm.
