How Do You Kiln Tyres Migration Calculation

Kiln tyres migration, also known as rotary kiln axial migration or tire slip.
This is an important parameter to monitor in rotary kiln operation, as it can affect the overall performance and efficiency of the kiln.
Kiln tire migration refers to the movement of the kiln tire relative to the rotary kiln shell, and it is typically measured in millimeters or inches.

Kiln Tyre Migration Calculation


  1. Initial Position
    Measure the initial position of the kiln tire.
    This can be done by taking measurements from a reference point or mark on the tire to a fixed point on the kiln shell.
    Ensure that these measurements are taken accurately.
  2. Monitoring Period
    Decide on the monitoring period.
    Kiln tire migration is calculated over a specific time frame, so you need to determine how often you will take measurements.
    The monitoring period can vary depending on the kiln’s size and operating conditions but is typically done at regular intervals, such as weekly or monthly.
  3. Subsequent Measurements
    Periodically take measurements of the kiln tire position during the monitoring period.
    Again, measure from the same reference point or mark on the tire to the same fixed point on the kiln shell.
  4. Calculate Migration
    To calculate the kiln tire migration, subtract the initial position (from step 1) from the final position (from step 3).
    The result will give you the tire migration for that specific monitoring period.

Mathematically, you can represent this calculation as:
Kiln Tire Migration = Final Position – Initial Position

Analyze the calculated migration values over time.
If the migration is within acceptable limits and does not change significantly over time, it indicates stable kiln operation.
However, if there is a significant increase in migration, it may be a sign of issues with the kiln’s alignment, mechanical problems, or other operational concerns that need to be addressed.
If you find that the kiln tire migration exceeds acceptable limits or is trending in an undesirable direction, you may need to make adjustments to the kiln’s alignment or address any mechanical issues to maintain stable operation.

It’s important to note that kiln tire migration monitoring is just one aspect of rotary kiln maintenance and operation.
Regular inspections, maintenance, and alignment checks are essential to ensure the kiln’s efficient and safe operation.
Additionally, specific industries and kiln types may have their own recommended practices and tolerance limits for tire migration, so it’s essential to consult relevant guidelines and experts in the field.

Kiln Tyre Material


During the production process of kiln tyres, it goes through a series of strict steps.

  • First, raw materials such as carbon steel, alloy steel, etc. are precisely cut and processed and then welded into the ring structure of the kiln tire.
  • These kiln tires undergo heat treatment and finishing after welding to ensure their strength and dimensional accuracy.
  • Quality control is a critical part of the manufacturing process, ensuring kiln tires meet design and specification requirements.
  • Finally, the kiln tire may require painting and corrosion protection to extend its service life.
  • The entire production process emphasizes the importance of quality and durability to meet the needs of various industrial applications.

Kiln tires process

The choice of production materials for rotary kiln tyre is crucial.

Common materials include carbon steel, alloy steel, stainless steel, and cast iron.
These materials have different characteristics and can meet the needs of different industrial environments.
The material selection of a kiln tyres must take into account factors such as temperature, pressure, chemical environment, and load of working conditions to ensure that its performance and life span meet requirements.

  • Alloy steel kiln tires are often used in high-temperature and high-stress environments such as cement production due to their high strength and wear resistance.
  • Stainless steel kiln tires are suitable for applications requiring high corrosion resistance, while cast iron kiln tires are typically used in smaller rotary kilns and low-temperature environments.
