Dear experts,
i have a problem that kiln RPM at operating station and actual at site have difference of about 0.3 RPM.How can i solve this problem.
Is there any formula regarding this?

Check first how you get the indication of kiln speed from field sensor going to your PLC or CCR monitoring system. If there is a program to convert kiln speed based on motor rpm, then just add a factor (% error) if the error is the same on all kiln speed settings. If not, then ask your automation to calibrate your tachometer. The formula usually is based on the gear (in/output) ratio of the gearbox - kiln pinion and master gear and speed of motor.
If you're running at kiln nominal speed with 0.3 difference, that is not much of a problem. Kiln speed is not always constant and varies on some degrees depending on the coating, burning zone conditions, etc.
