NJ-3 Microcomputer Adhesive Index Tester Adhesive Strength Tester

Overview of Bonding Index Tester:

The NJ-3 caking index tester is a * * * instrument to measure the caking capacity of coking coal -- Roga index and caking index. A certain amount of coal samples are mixed with a certain amount of * * * coal (inert substances) evenly, so that the coal samples (small particle size) are uniformly attached to the surface of * * * coal (large particle size). The colloidal substance generated from middling coal samples in the process of carbonization binds the particles of * * * * coal together, and then the * * * drum is used for rotary milling test to determine the * * * strength. To determine the bonding ability of the coal sample (coal colloid) to * * * coal. Then use specific formulas to calculate the cohesiveness of the coal sample. This instrument is suitable for laboratory use in coal, metallurgy, coking departments, and research institutions.

NJ-3 Microcomputer Adhesive Index Tester Adhesive Strength TesterPerformance characteristics:

This instrument is used to determine the bonding ability, bonding index, and Roga index of coking coal.

The drum sensor adopts imported integrated electronic switches, which have the characteristics of long service life and strong anti-interference performance. Simple structure, * * *.

The gearbox does not need to be filled with oil, which solves the problem of gearbox oil leakage.

No need to set the number of drum cycles, computer automatic control.

Automatically remember the number of startup times.

Display method: LED digital display, manual reset or automatic reset when turned on.

Structure composition of adhesion index tester:

1. Chassis: It mainly serves to fix the components, with all parts installed inside the chassis, while also preventing dust, reducing noise, and having a beautiful appearance.

2. Motor: The instrument uses a ***** low-speed motor, which has low speed, low noise, low error, and low power; The characteristic of high torque. It is a motor specifically designed for this instrument.

3. Drum: It is the main executing component of the instrument for measuring the adhesion index, arranged on the left and right sides of two drums. Before starting work, loosen the butterfly nut of the drum cover, then load the material into the drum, cover the drum cover, and lock the nut. The motor can be started and the testing process can be carried out.

4. Control panel: The control panel has start and stop buttons, and a speed display window. Press the start button to start the work, and the instrument will start working. The display window will show the number of revolutions transmitted. If there is an abnormality in the working process, you can press the stop button to stop the machine from rotating. Press the start button again to start the machine again.

Precautions for machine use:

1. The correct usage method and thorough maintenance can help extend the service life of the machine. Please follow the instructions in the operation manual.

2. When the power supply in the working environment is unstable, please install a voltage regulator and pay special attention to the regulations on power supply, humidity, and temperature in the manual, and maintain the machine properly.

3. The machine itself and its surrounding environment should be kept clean.

4. Please do not dismantle the components or move the internal parts of the machine at will.

5. If there is any abnormal situation with the machine, please do not continue to use it. Please notify the agent immediately or contact our company directly to inform them of the machine name, model, and factory serial number.
