Abstract: A screen assembly includes a frame having an outer perimeter and at least one inner support member, and at least one smooth surface affixed to the frame, where the smooth surface(s) have perforations. The frame may include a plurality of contact points extending upward from a top surface, and at least one smooth perforated screening surface is affixed to the plurality of contact points on the frame. In some cases the smooth surface comprises a perforated region and an erosion resistant region. Also, the perforations may have a shape that includes one or more corners. The smooth surface may be a perforated metal foil, sheet metal, and the like. Perforations may be apertures having one or more opening area sizes across the span of the screen assembly.

Abstract: A shaker separates components of a slurry. The shaker has a screen with a pressure differential applied to the screen to remove a portion of a slurry. The pressure differential across the screen can be toggled or pulsed. Generally, various types of separators are used to separate liquids and solids. For example, oil-field drilling operations use separators with screens to remove solids from a slurry. One type of apparatus used to remove solids from drilling mud is commonly referred to in the industry as a “shale shaker.”

Abstract translation: 振动器分离浆料的组分。 振动筛具有施加到筛网上以除去一部分浆料的压力差的筛网。 屏幕上的压差可以切换或脉冲。 通常，使用各种类型的分离器来分离液体和固体。 例如，油田钻井操作使用带筛网的分离器从浆料中除去固体。 用于从钻井泥浆中去除固体的一种类型的设备在工业中通常称为“页岩振荡器”。
