Dear all .which method used for measurement to clinker temperature from cooler exit ?
M.Azhar
hello every one ,we are using pyrometer , located 4 to 5 meter distance from the pan conveyor............

A pyrometer will not report proper clinker temperature because it is overly sensitive to pieces of clinker with higher temperature (red pieces coming from big blocks broken by the crusher).
Only good method is to build a "thermo box" i.e. a bucket externally lined with a thick layer of insulation + insulated cover with a hole for a thermocouple. Quickly fill the box with clinker from the crusher chute or the conveyor, insert the thermocouple and record the temperature over time. As the box is insulated, the temperature will stabilize after 15 mins or so and then slowly decrease. From the decrease, you can extrapolate linearily to time zero to get the average clinker temperature. If the box is really well insulated, the decrease will be so slow that you can read the temperature directly.
You have to repeat this measurement a few times to get a godd picture of your clinker temperature.

But The Temperature will get damaged frequently.Is there is any other technique to find the clinker temperature by conduction?ovancantfort:
