美国阿那康达矿物公司比尤特铜选矿厂的新过滤车间投产还不到11个月,出厂的铜精矿水分就平均达到9%以下。比尤特选矿厂新建工程的核心是安装了三台由 Ingersoll--Rand 公司生产的“Lasta”型自动压滤机(型号为1500×44/38),这是在美国用于有色金属精矿过滤的首批自动压滤机。Lasta 压滤机的工作周期,因使用得克萨斯仪表公司产的 PM550型程序控制器(即使用现代化的电子和风动仪表)而实现了最佳
The new filter plant at Bit Steel Plant, Anakonda, U.S.A., is in operation for less than 11 months, delivering up to 9% copper concentrate ex works. At the heart of the new Butte Concentrator project is the installation of three “Lasta” automatic filter presses (Model 1500 × 44/38) by Ingersoll - Rand, which are used in the United States for non - ferrous metal concentrates Filtering the first batch of automatic filter press. The duty cycle of the Lasta filter press is best achieved with the Texas Instruments PM550 Programmer (using modern electronics and pneumatic instrumentation)
