    高效精密平面回旋筛具有设计合理,结构简单,运行平稳,全封闭结构,无尘染,防堵孔,防粘网等优点。特别是对吸湿性强、粘性大、易堵孔和粘网的尿素筛分更为明显。由于采用了平面回转运动原理,有效的降低了设备的动静比和基础动载荷。该设备采用平面回转振动筛上下振动,网下有自动清理设备,较传统的直线筛而言,提高了丝网寿命,噪音小,筛分面积大,将效率由原来的93~95提高到了99,推广前景好 。pxzs型平面回转尿素筛分机主要是针对大颗尿素的筛分开发的一种新型筛分设备,也广泛应用于冶金、矿山、化工、医药、建材、粮食加工、耐火材料等行业的精确分级筛分作业。是一种新型的高标准筛分设备,该系列设备具有筛分效率高,筛网利用率高,工作稳定可靠,不易将合格的颗粒振碎,无污染,是一种理想的环保型筛分设备。
    Efficient and high precision plane whirl screen has a advantage of reasonable design, simple structure, smooth operation, fully closed structure, dust-free dye, prevent hole, anti-sticking net and so on.Especially the hygroscopicity strong, big viscosity, easy to plug holes and mesh the twigs of urea is more apparent.Due to the principle of plane rotary motion is adopted, which can effectively reduce the equipment of dynamic load ratio and foundation.Vibrates the device adopts the plane rotary vibrating screen, off-line automatic cleaning device, compared with the traditional linear screnn, improve the working life, the small noise,largescreening area, the efficiency has been increased to 99 from 93 to 95, good promotion prospects.PXZS type plane rotary urea sieving machine mainly for large urea of screening and development of a new screening equipment, is widely used in metallurgy, mining, chemical industry, medicine, building materials, food processing, refractories and other industries precision classification screening operation.Its a new type of high standard screening equipment, the series equipment has high screening efficiency, high utilization rate of screen mesh, stable and reliable work,  not easy to break the qualified particle vibration, no pollution, is an ideal environmental protection screening equipment.

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.

平面回旋筛物料运行轨迹

Moving trajectory
回旋筛物料运行轨迹     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.
