A spiral swirler

Technical Field The present invention relates to processing equipment, in particular a helical swirler. Characterized in that: the other supporting column is fixedly connected to the helical cavity consist support column and a support column centered and thus, the upper spiral cavity, close to the support column is provided at the mine mouth, the lower portion of the helical cavity, near the support column is provided at a lower portion of fine ore outlet, the spiral cavity, close to the edge of the spiral cavity with coarse ore outlet connected to the inlet mine ore pipe through the connecting flange, fine ore outlet connected by flange fine ore outlet tube, coarse ore outlet connected via the coarse ore outlet tube flange. Spiral cross-section of the cavity and the other by a circular chamber communicating with the circular chamber chamber approximately triangular configuration. Simple structure of the present invention, completely avoid shunting occurs, to improve classification accuracy, high classification efficiency, wide processing grain size, can be processed - fine mineral, a wide range of applications.
