、国内目前工业上使用的各种水力旋流器的给矿方式,都是给矿口沿筒体切线方向直接给入的,这种进矿方式不但加速筒体上端顶盖的磨损,同时还会导致整个旋流器内表面的螺旋线刻槽,从而影响了分级效率和使用寿命。六十年代,我们在总工程师倪桐材指导下,就试图采用螺旋线(或渐开线)给矿代替切线给矿。试验室试验已获得了肯定 , The current domestic industry to use a variety of hydrocyclones to the mine, are fed to the mouth along the tangential direction of the cylinder directly into the, this way not only to accelerate the top of the barrel to wear the top cover, but also Will lead to the spiral groove of the inner surface of the cyclone, thus affecting the classification efficiency and service life. In the 1960s, under the guidance of Chief Engineer Ni Tiantu, we tried to use spirals (or involutes) instead of tangential lines to mines. Laboratory tests have been affirmed
