60年代大型浮选机在市场上出现,这是世界使用更大型浮选设备的倾向的一个方面。促进这个发展的决定性作用的一个因素是:需要不断开采较贫的矿石而使矿石处理量增加,而日益使用仪器和自动化也是一原因。 1970年,在奥托昆普公司成立一个为研制浮选机的工作组。这个组的主要任务是设计和研制新型高效的尤其能弥散大量空气的转子,和比现有显著大规格的机械——充气的浮
Large flotation machines of the 1960s appeared on the market, an aspect of the world’s tendency to use larger flotation equipment. One of the factors contributing to the decisive role of this development is the need to continuously mine the poorer ore to increase ore handling, and the increasing use of instrumentation and automation is also a factor. In 1970, Outokumpu set up a working group to develop flotation machines. The main task of this group is to design and develop a new and efficient rotor that can disperse a large amount of air in particular and a significantly larger mechanical-pneumatic float
