Is a „banana” on a rotary kiln a death sentence for the refractory lining?

hot kiln alignment

I often encounter the belief that kiln alignment is a task reserved exclusively for shutdowns. Nothing could be further from the truth. A rotary kiln is a „living organism” that operates under extreme thermal conditions. Why is Hot Kiln Alignment (HKA) critical? ▪️ Thermal Deformations:A kiln behaves differently during operation than when it is „cold.” […]

Ovality

hot kiln alignment

Ovality measurement Ovality is a measurement of how well a kiln shell is able to support refractory. Rotary kiln refractory brick linings depend on the principal of the continuous arch to stay in place. Naturally any forces acting on that arch, such as flexing kiln shell, will act to deteriorate the mechanical stability of the

Kiln Shell

Rotary Kiln Shell Deformations Local deformation of kiln shell has a negative effect on brick lining inside the kiln, shortening its lifetime. It is recommended to control lining condition at every kiln renovation stoppage. When the loss of lining is observed still in the same place the shell segment replacement should be taken into account.

Kiln axial balance

hot kiln alignment

Kiln axial balance The axial balance of the kiln is depended on many factors which include: geometrical position of support rollers both in horizontal (skew of rollers) and vertical planes (inclinations), mechanical wear of running surfaces of tires and rollers. Each of these elements generates an axial force acting on the kiln in a particular

Kiln axis

hot kiln alignment

Kiln axis The axis of the kiln in a vertical plane is directly related to the value of the under-tire clearance and temperature distribution. In the case of changes of temperature distribution of the kiln, both the axis position and the value of clearance is not constant. Besides, any change in position of the axis
