In our country, it mainly divided into magnetite, limonite, hematite, siderite, such as iron sulfide ore deposit. We panzhihua The iron ore reserves is extremely rich in Pan zhihua. The hardness of iron ore is higher and hongxingly uses short head conical for crushing work. Magnetite is the most high quality iron ore.The main ingredients are Fe3O4, Fe2O3 and FeO of complex, It have the magnetic. Magnetite Mohs hardness roughly is 5.6 to 6 and the ore color is dark gray. After long-term weathering, the magnetite will become hematite. Crushing magnetite need to use crushing equipment. According to weathered degree, we can choose different crushing equipment. Generally, the cone crusher is used for magnetite ore with higher content and non-obvious weathering. Such as Sichuan Pan zhihua area where have rich magnetite. They often use short head type cone crusher. And in the most regions of north, the magnetite sources weathering is serious, and then the jaw crusher is extensive production.At the present, Hongxing mining machinery has...
