Introduction: NJ-2 bond index tester is to determine the coke coal binding capacity - Roja index and bonding index of special equipment. It consists of a motor through worm gear reducer driven two drums at a speed of 50 revolutions per 250 turns, so that coal-like coke block in the drum for strength test. Thus the coal block abrasion resistance, that is, the size of the resistance to failure that the bondability of the sample. Bond analyzer consists of five parts, namely motor, reducer, drum, counter, shell and so on. The instrument is equipped with electronic counter and control device, the factory set the number of revolutions to 250, to achieve automatic stop, you can also increase or decrease the number of turns according to special requirements. Counting detection using photoelectric switch, with no contact, long life and so on. Bond tester suitable for coal, metallurgy, coking departments and research institutes to use the laboratory. Technical Parameters: 1. In line with national standard GB / T5447-2014 "Determination of bituminous coal adhesion index" and GB / T5449-2015 "Determination of Roca index of bituminous coal"; 2.Display: double LED digital display, the left shows the count window, the right shows the clock window, manually reset or set the number of laps; 3. Drum rotation: 250 rpm; rotation speed control range: 1-999 turn can be preset; Drum speed: 50 ± 0.5r / min; 5. Motor power: 120W; 6 total weight: 35kg, host: 20Kg; 7. Power: AC 220V ± 10% 50Hz; 8. Dimensions: Host: 480mm × 370mm × 280mm (length × width × height)
