BLL螺旋溜槽是根據(jù)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(chǎn)生礦漿動(dòng)感的離心流膜，在重力和離心力的綜合立場(chǎng)中，利用不同顆粒所受重力，水動(dòng)壓力和摩擦力，實(shí)現(xiàn)有用礦物于脈石分選。螺旋槽中的水動(dòng)除作向下的螺旋運(yùn)動(dòng)外，還作橫向的循環(huán)流動(dòng)。上層水流流速快，產(chǎn)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(zhuǎn)速度慢，離心力小，在重力作用下從外緣流向內(nèi)緣，產(chǎn)生二次回流。礦漿中的重礦粒沉降快，沿收斂的螺旋線(xiàn)逐漸向內(nèi)緣，后以精礦形式產(chǎn)生。輕礦物沉降慢，處于礦流表層，流速快，離心力，子啊橫向環(huán)流作用下，沿?cái)U(kuò)漸的螺旋線(xiàn)逐漸移向外緣，后以尾礦形式產(chǎn)出。本產(chǎn)品由原地礦部指定企業(yè)生產(chǎn)，執(zhí)行行業(yè)標(biāo)準(zhǔn)。

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.
