在选矿厂中,破碎和磨矿的操作费用约占全厂总加工成本的60～70％。因此,必需正确地选择磨机和磨矿回路的自动控制系统,以降低破碎系统的经营费用。 自磨和半自磨 过去的十年,在矿物加工业中趋向于安装自磨机和半自磨机,特别是在大型选矿厂,更要考虑采用这种磨矿工艺。这样可以减少第二或第三段破碎系统,及与其相关联的辅助运输系统,既降低了投资,又可取得较好的经济效益。 自磨机的进料一般为破碎后的150～300毫米的矿块。在有些选矿厂,如菲律宾的Bengnet联合公司的Dizon选矿厂,美国俄
In the concentrator, crushing and grinding operation costs account for about 60 to 70% of the total processing costs of the plant. Therefore, it is necessary to correctly select the automatic control system of the mill and grinding circuit to reduce the operating costs of the crushing system. In the past decade of self-polishing and semi-self-abrasion, self-and semi-autogenous mills have tended to be installed in the mineral processing industry, especially in large beneficiation plants. This can reduce the second or third paragraph crushing system, and its associated auxiliary transport system, both to reduce investment, but also get better economic benefits. Since the mill feed is generally 150 ~ 300 mm after the crushing of the nuggets. At some concentrator plants, such as the Dizon Concentrator at Bengnet Associates in the Philippines, the United States
