随着浮选厂自动控制技术的发展,在浮选剂添加方面也有很大进展,廿世纪七十年代按浮选最佳条件实现自控的厂不断出现,各种自动阀是遥控的主要手段。另方面,在浮选药剂的添加方法中,廿年代英国Denver公司设计的各种加药机,在国内外选矿厂中仍在广泛运用着,国内中小型选矿厂中有的使用浮标式加药器或各种简易开关。本文提出的液压加药系统,由于它可以在一个大气压的万分之一内进行调节,加药量可在每分钟添加几毫克至几公升的范围内变动。从而具有较高的加
With the development of automatic control technology in flotation plant, great progress has been made in the addition of flotation reagents. The auto-controlled factories under the optimal conditions of flotation in the 1970s are constantly emerging. Various automatic valves are the main means of remote control. On the other hand, in the adding method of flotation reagents, various dosing machines designed by Denver Company in the United Kingdom in the 1920s are still widely used in the concentrator at home and abroad. Some domestic medium and small-sized concentrators use buoyant dosing Or a variety of simple switch. The proposed hydraulic dosing system, because it can be adjusted within one ten thousandths of an atmospheric pressure, the dosage can be added within a few milliliters to several liters range per minute changes. Which has a higher plus
