pellet binder
The pellet binder developed by Our company. is a new type of pellet binder developed on the basis of integrated pellet additive and sodium bentonite technology. The additive, based on the theory of pellet consolidation, can completely replace the ordinary sodium bentonite in the existing production process from the existing production process of pellet plant. It is an ideal technology for iron reduction and reduction of iron in the iron making system. The additive consists of six parts: pellet, early strength agent, melting agent, crystal conversion control agent, oxidant and explosion-proof agent.
1, cancel common sodium bentonite, reduce the ratio of binder, and ensure the strength of raw balls and reduce ore returning.
2, increase the burst temperature of pellets and increase the yield of pellets.
3, promoting pellet roasting and oxidation process, controlling unreasonable lattice transformation, and improving metallurgical properties of pellets.
4, improve the iron content of pellets, reduce impurity content, and create energy saving benefits for iron making process.
Report on the test of iron powder making
Iron powder
The iron powder used in the test is supplied by WISCO, slightly red, dark red after drying and mixed with converter iron and other iron containing materials.
1. The water of iron powder: 9.91%
2. Grain size of iron powder: -200: 63.2%. -325: 34.6%
The composite pellet binder for testing is provided by our company. The following are the following indicators.

Ball making test
1, the parameter of the ball plate
1) the diameter of the ball plate: 1000
2) disc speed: 20-23r/min
3) dip angle of the ball: 450
2. The process of making ball
The 2Kg iron powder was added and the amount of bentonite powder was mixed. The mixture was crushed and mixed with a flat shovel to make the ball. During the ball making, the ball was made in 1min, the mixture in 9min was added up, and after the dense 3min was taken out, the raw balls were tested.
2.1 birth ball quality testing program
Determination of water in 2.1.1
After the ball was taken out, the raw ball was immediately called in the iron (or porcelain) plate, which was dried to constant weight in an electrothermal constant temperature drying box, which was heated to 105. 5.
Determination of the falling strength of 2.1.2
Take 10 balls of raw ball and fall freely on the iron plate at the height of 50cm (or 45cm), and record the number of cracks in the ball each time. The number of cracks is recorded at the number of 0, 1, 2 and 3... The average drop times of the ball are calculated after the whole ball is broken. Repeat the test 3 times according to this procedure, and finally calculate the average number of falling balls.
Determination of the compressive strength of 2.1.3 raw ball
Take 10 balls, press the balls on the spring scale, record the pressure of the broken balls, and calculate the average pressure of the 10 balls. The pressure is Kgf and the result is 9.8 (N).
Determination of the burst temperature of 2.1.4
50 balls are taken and placed in a special device which has been heated to a certain temperature. 7min is tested under the ventilation of 1.8m/s, and the crack condition of the pellet is checked after a slight cold. The temperature of the cracking of 2 balls when the 50 balls appear is its burst temperature.
2.2 binder selectivity test
In the process of ball making test, the addition of alkali amount, different polymer binder and its amount in the binder is added to the properties of the binder. At the same time, the time and the water of the ball are controlled, and the ratio of the product is determined, and the test of the ball and the quality of the ball are tested. Test.
