The blast furnace slag ball mill is used for professional production of ground blast furnace slag. Blast furnace slag is a material composed of calcium oxide, sulfur dioxide and chlorine trioxide. It is a by-product of blast furnace iron making, which will pollute the air and cause human respiratory diseases. The blast furnace slag ball mill can effectively process the slag and obtain the ground blast furnace slag with the particle size of 0.074-0.89mm, so as to meet the processing requirements of different enterprises for blast furnace slag.
The blast furnace slag ball mill is different from the conventional ball grinding mill in structure due to the coarse grain is less and the large plasticity of the iron and iron oxide components. Usually cement mill advocates more crushing and less grinding, but this is not suitable for blast furnace slag grinding. The blast furnace slag has a uniform particle size, and only needs to be pre-screened when controlling the grinding particle size. The wear of blast furnace slag on blast furnace slag ball mill mainly comes from iron and iron oxide. These two materials have large plasticity and are not easy to grind in the blast furnace slag ball mill, which will cause them to accumulate in the grinding system, which will increase the wear of the slag ball mill. According to the characteristics of blast furnace slag, the blast furnace slag grinding line is equipped with a magnetic separator for iron removal.
