試驗BLL螺旋溜槽技術參數

Technical Parameter of laboratory BLL Glass Fibre Reinforced Plastic Spiral Chute

BLL螺旋溜槽是根據有用礦物與脈石礦物在比重、粒度、形狀上的差異，在螺旋的斜面產生礦漿動感的離心流膜，在重力和離心力的綜合立場中，利用不同顆粒所受重力，水動壓力和摩擦力，實現有用礦物于脈石分選。螺旋槽中的水動除作向下的螺旋運動外，還作橫向的循環流動。上層水流流速快，產生較大慣性離心力，甩向槽的外緣。與槽底相鄰的下層水流回轉速度慢，離心力小，在重力作用下從外緣流向內緣，產生二次回流。礦漿中的重礦粒沉降快，沿收斂的螺旋線逐漸向內緣，最后以精礦形式產生。輕礦物沉降慢，處于礦流表層，流速快，離心力，子啊橫向環流作用下，沿擴漸的螺旋線逐漸移向外緣，最后以尾礦形式產出。本產品由原地礦部唯一指定企業生產，執行行業標準。

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.
