矿浆预处理设备的应用进展
|
摘要
矿浆预处理是浮选之前必不可少的作业,对实现目的矿物的充分矿化、分散,与浮选药剂的充分反应,提高浮选指标有重要意义。矿浆搅拌槽应用范围最为广泛,近年来其结构改进后也更加节能高效;叶轮搅拌式混合器和矿浆准备器起源较早,但是由于易造成环境污染、药剂混合效果差等原因逐渐淡出市场;雾化跌落箱和管道混合器主要应用在选煤领域,具有节能、操作简单等优点,应用较广泛,但是跌落箱庞大的体积以及管道混合器混合时间短、作用不充分等劣势也制约了其发展;矿浆改质机由于可以高效分散药剂和混合矿浆,使其成为近年来的研究热点,应用领域也由非金属矿逐渐向金属矿拓展,具有广阔的前景。指出缺少矿浆预处理器搅拌效果的直接评价方法,现有搅拌器专用性差,今后可以从药剂分散程度、矿浆和药剂的混合程度或者药剂吸附的状态等方面对搅拌槽的效果提出更直接的判断。不同的矿石,需要的搅拌条件不同,需进行有针对性的改进。
It is an indispensable to pulp pre-process before flotation, for it's great importance for purpose minerals mineralization, dispersion,mixing with reagents, and finally improving flotation index. Specifically, conditioners are most widely used and its continuous optimization makes it more efficient and energy-saving; Impeller agitating type mixer and pulp preparation device origin early but gradually fade away due to their pollution and poor mixing effect; spray-drop cabinet and pipeline mixer are mainly used in coal purification with their advantage of energy-saving and simple operation,while the giant volume of cabinet and short mixing time in pipeline constraint the application of the two device; Pulp surface modifier becomes a research hotspot due to its high dispersing and mixing efficiency and its application covering both non-metal and metal mine.It is pointed out that there is a lack of direct appraising method of mixing effect and current mixer needs specially designed.Research should be focused on the degree of reagent dispersion, mixing with minerals,or absorbing on minerals surface to evaluate mixing effect directly. Besides,different types of minerals need different mixing environment and mixers should be modified correspondingly.
