?????? ：?重要设备, 垂直筛分效率直接影响成品质量和投资成本。
许多矿主在生产过程中遇到许多麻烦，例如 振动筛 can’t reach the expected processing capacity or low screening efficiency in the process of production. ?重要设备, 垂直筛分效率直接影响成品质量和投资成本。
通常，振动筛的筛分效率与一些因素（例如材料性质、设备结构和各种性能参数）有关。除了选择振动筛的基本要求（材料性质和设备结构）外，今天我们主要分析与振动筛效率相关的五个重要性能参数：振动筛的振动频率、振动方向角、筛面倾角和抛射角。
振动筛的振幅
In general, the larger the size of the 振动筛, the larger the amplitude selected. That’s because the larger amplitude means there will be less of screen hole plugging, this will be more conducive to ore screening stratification and realize a better screening capacity. But it should be noted that: if the amplitude of the 振动筛 is too large, strong vibration action may damage the equipment itself.
振动筛的振幅通常由矿石粒子和特性决定。例如，当矿石粒子小而潮湿且具有一定的粘度时，我们需要使用低频率和大振幅的振动筛。

In actual production, most linear 振动筛s adopt vibration direction angles of 30°, 45° and 60°. That‘s because this kind of angle can not only adapt to various screening performance, but also obtain the best moving speed and screening efficiency.
