Memorandum for Sin Mian (cement group) till now

I have qu estions for 5E -MAG66 00B. We want to test the loss on ignition for cementand raw material sample by using 5E-MAG6600B machine. Is it possible or not ? Allof the test results are ok. Machine operation is smooth. Everyday I can testing forcoal according to your instruction. Please reply me.Today cement testing is OK, I will ask my manager for pulverizer.Thank you very much for your information.
