Hematite Ball Mill. Hematite is an iron oxide with an iron content of around 70%. It generally has a hardness of 5 to 6 and appears in red to light gray, sometimes black or streaked with dark red. For this type of iron ore, a grid-type ball mill is commonly chosen as the first-stage grinding mill, followed by an overflow ball mill as the second ...
Reason: This is a common problem mining ball mills face, resulting in low productivity and low ore processing efficiency. One reason may be the improper design of the grinding chamber, which affects the flow of materials and reduces grinding efficiency. Additionally, worn or damaged liners can hinder the grinding process by reducing the …
