振动筛

The relative motion of particles with the screen surface is mainly parallel to the movement of bar screen, flat vibrating screen, sieve tube, with its screening efficiency and productivity are low.

再就是筛子的振幅与振次，这与筛子的结构物性有关，在一定的范围内，增加振动可以提高筛分指标。

Electromagnetic vibrating sifter from the electromagnet, screen, frame, spring contactors etc., using a higher frequency and smaller amplitude of vibration.

电磁震动筛粉机由电磁铁、筛网、架、弹簧接触器等组成，利用较高的频率与较小的振幅产生振动。

Motion law of scrap plastic film and sundries on the separating sieve was analyzed.

试验表明，分离筛的振动频率对残膜的分离率影响较大。

The rigid-flexible coupling dynamics modeling and modal analysis were employed to study the system consisted of square plansifter and flexible suspender.

针对高方平筛和其上固结的柔性吊杆组成的动力学系统，进行了刚柔耦合的动力学建模和振动模态分析。

The this design structure and sieves ordinary is dissimilar, it has 4 side bars, the middle both sides are main, the vibrator installs above it, by it to the screening surface transmission vibration power, outside two is secondary, only plays keeps off the yard lumber the role.

该设计结构与普通筛不一样，它有4块侧板，中间两侧是主要的，振动器安装在它上面，由它向筛面传递振动力，外面两块是次要的，只起挡料板的作用。

Finally taking the dimension of the screen hole and the obliquity of the screen face into accounts and measuring all kinds of vibration of a self-making jumping screen, we validate the theory.

最后，对自制的弹跳筛样机重要部分的振动情况进行测定，并用实际测定的结果来验证理论分析的结论。

My company mainly produces dust removal equipment and transportation equipment (anti-briefing bag filter, pulse dust collector, the conveyor belt, bucket elevator, buried scraper conveyor, conveyor chain, screw conveyor, conveyor chain plate), Various models of broken equipment, vibration feeding, screening equipment, machinery parts, molds and other products.

我公司主要生产除尘设备和输送设备（反吹风袋式除尘器，脉冲除尘器，胶带输送机，斗式提升机，埋刮板输送机，链式输送机，螺旋输送机，板链输送机），各种型号破碎设备，振动给料、筛分设备，各种机械部件、模具等产品。

The bottom plate structure of screen box can be converted in order to improve grading ability.(5) It can adjust vibration frequency of screen boxes productivity and separation rate as needed.

筛箱底板结构可以转换，使分级能力提高；（5）筛箱振动频率可调，生产率和分离率可根据需要进行调节。

It sieves the box is board crossbeam riveting hitch welds built-up section By host vice- side bar Hollow beam Enters the material back plate Leaves material board Sieves board and so on composition The side bar selects the low-alloy pressure vessel steel plate The intensity is high The weldability is good Peripheral knee bend And in the vibration direction and along longitudinal connects themulti- roots angle steel Causes the side bar rigidity big enhancement Is advantageous to the intensity enhancement and noise reducing.

其筛箱为板梁铆焊组合结构，由主副侧板、管梁、入料挡板、出料板、筛板等组成，侧板选用低合金压力容器钢板，强度高、可焊性好，周边折弯，并在振动方向及沿纵向联接多根角钢，使侧板刚度大大增强，有利于强度的提高和噪音的降低。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
