Background
In the production process of metallurgical pellets, the proportion of-200 meshes of the granularity composition of iron ore concentrate participating in the pelletizing is required to be more than 80% in the pelletizing stage, the poor pelletizing property of raw materials is caused by the coarse granularity of the ore concentrate, so that more bentonite has to be added to ensure the green pellet quality, but when the addition amount of the bentonite exceeds 3%, the grade of finished pellets is obviously reduced. When the particles are wetted by water to exceed the water of the film in the pelletizing process, capillary water appears among the particles, the capillary water is continuously increased, and the surface tension or external force of the capillary water causes the particles to be close to each other, so that honeycomb-shaped capillary water is formed among the particles. Capillary water begins to connect between the particles and can migrate. Upon further wetting, saturated capillary water appears, reaching the maximum capillary water content. Capillary force pulls particles around the water drops to the centers of the water drops to form small balls, and when the materials are wetted to a capillary water stage, the balling process of the materials is developed. During pelletizing, capillary water plays a leading role. Therefore, the capillary water plays an important role in the whole pelletizing process. The content of capillary water in the iron ore concentrate participating in the pelletizing directly influences the pelletizing quality.
Therefore, the method for measuring the capillary water of the iron ore concentrate participating in the pelletizing plays an important role in the pelletizing in the production process of the metallurgical pellet ore.
