10.5 LRM – Live Ring Migration
In order to avoid kiln deformation that can damage refractory kiln torsion must be kept within certain
limits. Kiln shell torsion is greatly affected by the degree of clearance between the tires and the kiln
shell. The simplest and most accurate procedure is to measure the kiln shell's rotational speed as
compared to the rotational speed of the tires. The result is termed as tire slip. The Live Ring Migration
System is an automatic measurement and registration system designed to monitor tire slip and alert
the user when the system exceeds user-defined limits.
For an overview of a CS210 system with LRM, see section 13.2
page 115.
Delivery:
• Position indicator with junction box, 3 position indicators delivered for monitoring of 3 tires
(each further tire requires an additional position indicator XXXSYSECPI, up to 6 tires can be
monitored with the LRM system)

LRM Remote Control

10.5.1 Functionality

The LRM system monitors tire slip by measuring the rotational speed of the kiln shell and of each tire.
The rotation time differences between the shell and each tire are converted to a radial slip.
The electronics in the LRM remote control box captures the trigger signals from the different rings and
send <ring number> and <time stamp> to the PC via serial communication.
10.5.2 LRM Remote Control
The LRM remote control box contains a micro PLC and an RS485 communication port, all in a
protective housing. The measured values for the kiln and for each of the tires are then sent to the
computer through the RS485 port.
