Background
As is well known, a spiral separator is used as gravity separation equipment, and mainly realizes separation and separation processes of two-phase components by means of acting forces such as gravity, water flow acting force, centrifugal force and the like applied to materials in the process of moving on a spiral groove surface, and can be particularly used in the separation category of solid-liquid separation, solid-solid separation and the like. The spiral separator was first invented in the united states of america from 1898, and developed by hanflei in 1941. Subsequently, countries such as the Soviet Union, Germany, British, Australia, New Zealand, Canada, south Africa and the like successively develop spiral separators with various types and specifications for mineral washing processing. The spiral separator has been widely applied to the washing and selecting process of coal and non-coal minerals due to the characteristics of simple structure, high separation efficiency, no rotating parts, no power and the like. The separation principle is that ore particles in water flow are loosened and layered under the action of gravity, friction force, inertial centrifugal force, water flow dynamic pressure and the like, ore particles with high density enter a bottom layer and move towards an inner edge, ore particles with low density enter an upper layer and move towards an outer edge, a concentrate belt and a tailing belt are formed on the surface of a spiral groove, and finally, concentrate and tailing are separated through a material interceptor. The spiral separator has the technical advantages of simple structure and composition, convenient maintenance, low investment, no running parts and the like, but along with the increase of the washing quantity of raw coal year by year, the deterioration of coal quality year by year and the increase of the gangue content of the raw coal year by year in recent years, the gangue in a coarse coal slime system is increased year by year, the traditional spiral separator is not suitable for the current coal quality, the ash content of clean coal often exceeds the standard, and the phenomenon of 'back ash' of main washing clean coal is caused.
