The NJ-8 microcomputer bonding index tester is a specialized instrument for measuring the bonding ability of coking coal - Roga index and bonding index. It is suitable for laboratory use in coal, metallurgy, coking departments, and scientific research units.
Measurement principle
The NJ-8 microcomputer bonding index tester is driven by an electric motor through a worm gear reducer to rotate two drums at a speed of 50 ± 1 revolutions per minute, allowing the coal sample coke block to undergo strength testing inside the drums. The bonding ability of the sample is represented by the wear resistance of the coal block, which is the magnitude of the resistance to failure.
