As we all know, to protect the ball mill tube is beneficial to the service life of a ball mill, which can be used in iron ore processing line.
In the grinding process, for different grinding cavities, the requirements of the motion states of the grinding media are different. For example, the size of the block of the materials sent into the first grinding cavity is large. Therefore, the impact force of the grinding media should be big enough. After that, in each grinding cavity in succession, the impact force of the grinding media should be lowered increasingly. In the last grinding cavity, the impact force of the grinding media is supposed to be the smallest but the grinding force of the grinding media is the biggest.
In the iron ore processing line, the lining and the grinding media lining plate of a ball mill are used to protect the ball mill tube from the direct impact or friction of the grinding media and the materials. The lining plates of different shapes can also change the motion states of the grinding media and the materials in the grinding cavities. It should be known that, in the iron ore processing line, the grinding function of a ball mill is mainly realized by the grinding function and the impact, which the grinding media act on the materials
All the grinding cavities are rotating at the same speed. Thus, the lining plates in each grinding cavity should be of different shapes. Then, according to the concrete requirements of the grinding cavities, they should be equipped with the grinding media of different sizes, which can produce different frictions between the lining plates and the grinding media, in order to change the motion states of the grinding media. The grinding efficiency can be increased in this way. Besides, the materials of the lining plates are mainly made from the rubber which is of high wearing coefficient. And the materials of the grinding media are mainly made of high aluminum stone.
