NJ-8 micro-computer bond index tester is a special instrument for measuring the bond ability of coking coal-Roga index and bond index. It is suitable for the laboratory use of coal, metallurgy, coking departments and scientific research institutes. In line with the national standard GB/T5447-1997 "Bituminous Coal Binder Index Measurement Method".
Principle of measurement
NJ-8 microprocessor bond index tester is driven by a motor through worm reducer to rotate two drums at a speed of 50+1/min. The strength test of coal sample coke block is carried out in the drum, and the wear resistance of coal block, i.e. the size of failure resistance, is used to express the bonding ability of the sample.
Rotary drum speed: 50 + 1 rpm
Display mode: LED digital display, manual reset or automatic reset on boot.
Power supply voltage: 220V
Motor power: 120W
Shape size: 500 x 460 x 330 (length x width x height)
Weight: 45kg
