平面回旋筛工作原理

    从筛机摇动体即筛箱运动轨迹来看，平面回旋筛又称往复筛，其驱动装置所产生的振动力是一绕定轴、方向呈一定规律变化的惯性力，其本质是由偏心轮绕定轴转动所形成的往复惯性力。根据回旋筛的结构特点及工作原理，其筛面一般为水平或微倾斜布置。回旋筛的工作原理为:筛机启动后，筛机摇动体即筛箱在惯性力的作用下作前后往复运动，筛箱带动筛面作周期性摇动，从而使筛面上的物料随筛箱一同作定向跳跃式运动，期间，小于筛面孔径的物理通过筛孔落到下层，成为筛下物，大于筛面孔径的物料经连续翻滚跳跃运动后从排料口排出，最终完成筛分工作。

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.
 
    从平面回旋筛的结构和工作原理可以看出，其传动机构偏心轮距物料运动轨迹及物料在筛面上的滞留时间有至关重要的影响，也即对筛机处理能力和筛分效率有相反的影响，有鉴于此，在实际筛分作业中，我们可以根据具体情况和需要，在生产能力和筛分效率两方面有所取舍。
    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.

Moving trajectory

同样或相近的配置，平面回旋筛比一般惯性振动筛有更高的处理能力和筛分效率，其本质是，该机型可人为的控制物料在筛面上的运动轨迹和滞留时间，即在有限空间，由于物料的运动轨迹为速度和加速度均为变化非线性曲线，所以，物料与筛面有更多接触机滤，当然也就增加了透筛率。 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.
