石城县绿洲选矿设备生产 试验BLL螺旋溜槽技术参数Technical Parameter of laboratory BLL Glass Fibre Reinforced Plastic Spiral ChuteBLL螺旋溜槽是根据有用矿物与脉石矿物在比重、粒度、形状上的差异，在螺旋的斜面产生矿浆动感的离心流膜，在重力和离心力的综合立场中，利用不同颗粒所受重力，水动压力和摩擦力，实现有用矿物于脉石分选。螺旋槽中的水动除作向下的螺旋运动外，还作横向的循环流动。上层水流流速快，产生较大惯性离心力，甩向槽的外缘。与槽底相邻的下层水流回转速度慢，离心力小，在重力作用下从外缘流向内缘，产生二次回流。矿浆中的重矿粒沉降快，沿收敛的螺旋线逐渐向内缘，最后以精矿形式产生。轻矿物沉降慢，处于矿流表层，流速快，离心力，子啊横向环流作用下，沿扩渐的螺旋线逐渐移向外缘，最后以尾矿形式产出。本产品由原地矿部唯一指定企业生产，执行行业标准。BLL spiral chute is based on useful minerals and gangue minerals in the specific gravity, particle size, shape differences in spiral bevel dynamic centrifugal flow of pulp produced film, in the consolidated position of gravity and centrifugal force, the use of different particles suffered by gravity, hydrodynamic pressure and friction to achieve useful minerals in the gangue separation. Spiral tank of water movement except for a downward spiral, but also for the horizontal circulation. The upper water flow faster, resulting in a larger centrifugal force, inertia, Shuaixiang the outer groove. And the bottom adjacent to the lower flow turning slow, centrifugal force is small, the gravity flow from the outer edge of the inner edge, resulting in secondary reflux. Pulp in the heavy mineral grains settling faster convergence along the spiral gradually inward edge of the end, the form of concentrates produced. Light mineral deposition slowly, at a surface mine flow, velocity fast, centrifugal force, sub-ah horizontal circulation under the effect of gradually expanded along the line gradually moved towards the outer edge of the spiral, the end, the form of tailings output. This product is the only designated former Ministry of Geology and Mineral production, the implementation of industry standards. 型号Model单位UiteBLL-600BLL-400螺旋直径Screw diametermm600400螺距Spiral sizemm360240螺旋头数Spiral in the first few个 22每头圈数Each of the first fewFilm55给料粒度Feed sizemm0.30.3给矿浓度Feed density%20-4020-40处理量Caparating sizet/h 0.8-1.20.1-0.2外形Overall dimensionsmm700/700/2730460/460/1500重量Weighekg9060
