Shale Shaker Screen Material Selection and Structural Components
The material system of a Shaker Screen is a key factor determining its performance, covering not only the core screen cloth but also supporting plates, frames, rubber strips, and other auxiliary parts. For a high-performance Shale Shaker Screen, scientific material selection for each component is essential to meet the harsh requirements of drilling solids control operations. To fully grasp the material characteristics of Shaker Screen, it is necessary to first understand the basic structure of a Shale Shaker Screen panel.
StandardShaker Screen panel consists of three core components: screen cloth , supporting plate/frame, and rubber strips installed under the tubes. Among them, the screen cloth is the core functional part of the Shale Shaker Screen. It is usually made of high-quality 304~316L stainless steel, which provides excellent rust resistance and durability, ensuring stable screening effect in wet and corrosive environments. According to customers’ budget and actual application scenarios, different grades of stainless steel wire mesh can be customized for the Shaker Screen, achieving a balance between performance and cost.
The supporting plate that carries the screen cloth layers is mainly made of cold-rolled carbon steel plate with a thickness of 1.5~2mm, which has good structural strength and cost-effectiveness. Only a small number of customers with special requirements will choose stainless steel plates for their Shale Shaker Screen. These supporting plates need to be processed with punched holes of various shapes, such as rectangles, squares, triangles, hexagons, etc. In some complex applications, a single Shaker Screen can even adopt mixed hole shapes. For example, well-known brands like NOV Brandt®, VSM®, and Venom® use triangular holes of different sizes on their Shale Shaker Screen products to improve screening efficiency and throughput.
The frame structure of Shaker Screen varies according to product type. For steel-framed Shale Shaker Screen, the frame is formed by welding square steel tubes and supporting plates, which has strong load-bearing capacity and stability. For composite-framed Shaker Screen, square steel tubes are first welded into a stable skeleton, and then embedded into composite materials through injection molding. This composite structure not only maintains the structural strength of the Shale Shaker Screen but also enhances its durability and shock resistance, extending the service life.
In addition to traditional stainless steel Shaker Screen, polyurethane Shale Shaker Screen is also a popular product in the market. It is made of high-quality urethane material, with support rods embedded on both sides to further reinforce structural stability. A typical representative of this type is the polyurethane Shaker Screen produced by M-I SWACO™, which is highly praised for its excellent wear resistance and adaptability to harsh working conditions.
