What effect does mechanical damage have on refractory bricks? Let's take the lime rotary kiln as an example. The following introduction is also applicable to the field of rotary kiln equipment such as cement rotary kiln, lime rotary kiln, and lime rotary kiln.
In the actual operation process of lime rotary kiln, improper maintenance and use will cause the aging and damage of the rotary kiln equipment. The bricks located at the supporting rollers will be squeezed, and the bricks located at the top of the kiln barrel will be pulled by the weight of the kiln skin and its own weight. stretch. The bricks are subjected to comprehensive mechanical stress of compression, tension, torsion and shear in the kiln. The rotation of the lime rotary kiln, the ovality of the cylinder, the extrusion, twisting, and deformation of the kiln cylinder between the lining brick and the cylinder, and between the bricks, will produce mechanical stress between the brick linings. When the gap between the cylinder and the belt increases the ovality of the kiln body, the alternating stress of the lining bricks increases, and the mechanical stress on the belt is the most serious.

Take a lime rotary kiln factory as an example. After the bricks were renewed, the kiln barrel was bent, and the kiln lining was partially overheated due to severe vibration, which caused the barrel to deform and squeeze the lining, and the adjustment of the supporting rollers took time. Longer, the red kiln occurred at the No. 3 wheel belt, 6 meters away from the rotary kiln equipment, and the refractory bricks fell off in a large area. After digging and repairing, the supporting roller was adjusted to make the kiln body no longer vibrate.
According to the above description, the reasonable maintenance of machinery and reasonable operation and use can be described as the top priority of the manufacturer's operation. In order to give back to the majority of customers, if the user encounters technical problems in the use of lime rotary kiln, please call our company for details.
