The Test apparatus is specially designed to meet the MICUM test which is a relative measure of resistance of coke to degradation by abrasion.
The coke after selecting +50 mm size material through sieving is subjected to the Micum Test under standard conditions in a rotating drum. The drum is made to rotate for 100 revolutions at a rate of 25 rotations per minute (RPM) in approximately 4 minutes. The mean results of three Micum tests after size analysis with the help of sieves with the apertures in the size range of 60 mm to 10 mm are treated in the indices after taking cumulative percentages of retained material over 40 mm screen and 10 mm screen. This determines the resistance to breakage by abrasions.
The equipment complies with IS 1354.
The System consists of three parts:
1. Control Panel
2. Three phase drive
3. Rotating drum
