平面回旋篩工作原理

    從篩機搖動體即篩箱運動軌跡來看，平面回旋篩又稱往復篩，其驅動裝置所產生的振動力是一繞定軸、方向呈一定規律變化的慣性力，其本質是由偏心輪繞定軸轉動所形成的往復慣性力。根據回旋篩的結構特點及工作原理，其篩面一般為水平或微傾斜布置。回旋篩的工作原理為:篩機啟動后，篩機搖動體即篩箱在慣性力的作用下作前后往復運動，篩箱帶動篩面作周期性搖動，從而使篩面上的物料隨篩箱一同作定向跳躍式運動，期間，小于篩面孔徑的物理通過篩孔落到下層，成為篩下物，大于篩面孔徑的物料經連續翻滾跳躍運動后從排料口排出，最終完成篩分工作。

Working principles
Watching the track movement of the screen box, the plane whirl screen is also called reciprocating screen, vibration produced by the drive power, is a moving around a fixed axle direction in a certain regular changes of inertia force, its essence is formed by the eccentric wheel rotating around a fixed axle reciprocating inertia force.According to the structure characteristics and working principle of whirl screen, the screen surface is level or slightly sloping commonly decorate.Whirl screen working principle is: the sieve machine starts, shaking sieve machine body namely screen box in reciprocating motion, front and back the effect of inertia force operating screen box drives the screen surface to make periodic shaking, so that the material on the surface of the screen to make directional jumping movement, with screen box, smaller than the screen surface aperture physics by mesh drop to lower level, becoming the undersize, greater than the screen surface pore size of the material after continuous rolling jumping movement from the discharging mouth eduction, eventually completed screening work.
 
    從平面回旋篩的結構和工作原理可以看出，其傳動機構偏心輪距物料運動軌跡及物料在篩面上的滯留時間有至關重要的影響，也即對篩機處理能力和篩分效率有相反的影響，有鑒于此，在實際篩分作業中，我們可以根據具體情況和需要，在生產能力和篩分效率兩方面有所取舍。
    From the structure and working principle of plane whirl screen, you can see that the eccentric distance transmission material movement and material in retention time has vital influence on the surface of the screen, which is to screen machine processing power and screening efficiency have the opposite effect, because of this, in actual screening homework, we can according to the specific circumstances and needs of the two aspects of production capacity and screening efficiency.

平面回旋篩物料運行軌跡

Moving trajectory

同樣或相近的配置，平面回旋篩比一般慣性振動篩有更高的處理能力和篩分效率，其本質是，該機型可人為的控制物料在篩面上的運動軌跡和滯留時間，即在有限空間，由于物料的運動軌跡為速度和加速度均為變化非線性曲線，所以，物料與篩面有更多接觸機濾，當然也就增加了透篩率。 Same or similar configuration, plane whirl screen than general inertia vibrating screen has a higher capacity and screening efficiency, its essence is that the aircraft can be artificially controlled movement on the surface of the material in the screen and the residence time, namely in the limited space, since the trajectory for the velocity and acceleration of the material for the non-linear curve, so the material in contact with the screen surface has more machine filter, of course, increasing the screening rate.
