Description
技术领域technical field
本发明涉及一种选矿分选设备，特别是一种新型高频振动分叉螺旋溜槽。The invention relates to an ore dressing and sorting equipment, in particular to a novel high-frequency vibration bifurcated spiral chute.
背景技术Background technique
随着不可再生的矿产资源的不断开发利用，富矿资源日趋匮乏，原矿品位持续下降，以贫、细、杂为突出特点的难选矿石所占比例不断上升，致使常规的选矿方法和设备在技术和经济上面临严峻挑战。With the continuous development and utilization of non-renewable mineral resources, rich ore resources are becoming increasingly scarce, the grade of raw ore continues to decline, and the proportion of refractory ores with prominent characteristics of poverty, fineness, and miscellaneousness continues to rise, resulting in conventional mineral processing methods and equipment. and economic challenges.
螺旋选矿是一种简单、节能和高效的选矿方法之一。其中典型的设备为螺旋溜槽，其主体工作部件是一个螺旋形溜槽，其工作原理和过程为：矿浆自上部给入，在沿槽流动过程中发生分层，进入底层的重矿物颗粒趋向于内槽的内缘运动，轻矿物则在快速的回转运动中被甩向外缘，依靠颗粒密度的不同，矿物在槽的横向展开分选带。但是目前，随着磨矿粒度的降低，颗粒比重差异效应的下降，使得螺旋选矿在细颗粒矿物的分选方面存在许多问题，如细颗粒有用矿物容易混入尾矿带，分选效果差，造成精矿品位的下降，富集比的下降，尾矿品位的提高，回收率的下降等。Spiral beneficiation is one of the simple, energy-saving and efficient beneficiation methods. The typical equipment is a spiral chute, and its main working part is a spiral chute. Its working principle and process are as follows: the ore slurry is fed from the upper part, and stratification occurs during the flow along the trough, and the heavy mineral particles entering the bottom tend to go inside. The inner edge of the tank moves, and the light minerals are thrown to the outer edge in the rapid rotary motion. Depending on the difference in particle density, the minerals expand the sorting zone in the lateral direction of the tank. But at present, with the reduction of grinding particle size, the effect of difference in particle specific gravity decreases, so that there are many problems in the separation of fine-grained minerals in spiral beneficiation, such as fine-grained useful minerals are easily mixed into the tailings belt, and the separation effect is poor, resulting in The decline of concentrate grade, the decline of enrichment ratio, the increase of tailings grade, the decline of recovery rate, etc.
