Umerical study on collision process between particles and screen plate;2. Progress and trend of screen ers for fine difficult materials;3. The emulator,consisted of a feed hopper,a screen and a product baffle,can dynamically simulate the whole screen process.

ET开发了筛分作业的二维离散元仿真程序SieveDEM，模拟系统由给料漏斗、筛分机和产品隔板等组成，入筛物料的粒度组成、给料量及筛分机的工作参数等均可人为设定，实现了筛分作业全过程的动态模拟。

Features: high efficiency, small amplitude and high frequency of screening; it differs from the conventional screens with breaking of the surface tension of pulp and small granularity high speed vibration on sieve cover and accelerates the separating of large-density useful mines and increase the contacting probability of the materials smaller than output granularity and the sieve pore.

高频筛效率高、振幅小、筛分频率高。与普通筛分设备的原理不同，由于高频筛采用了高频率，一方面破坏了矿浆表面的张力和细粒物料在筛面上的高速振荡，加速了大密度有用矿物和析离作用，增加了小于分离粒度物料与筛孔接触的概率。

In addition, the diameter 400mm-1800mm the SF series vibrating screen vibrating object using a more advanced vibration molding tray, making shaker sieve screening machine has a higher efficiency, longer service life, product quality and performance have been achieved the level of the world's leading, fully able to meet the screening needs of different industries.
