Shaker screen features

Shaker screen is treated as important wearing part for shale shaker. Almost shale shaker screens panel consist following parts. The structure including frame, the back plate, then the screen cloth, seal rubber, etc. Lets find shaker screen features below.

Shaker screen frame

Much like a canvas for painting a screen has to be supported on a frame in order to do its job, this frame differs among manufacturers in both material and shape. Screen frames can be made from materials such as, square steel tubing, flat steel sheets, plastic, composites or they can just be supported on the ends with strips of steel (similar idea to a scroll). But the polyurethane screen doesn’t request frame only need 1 square rod on each side as support

These frames consist of a rectangular shaped outer perimeter which is divided into small individual inner panels. These smaller panels differ in shape from manufacturer to manufacturer and have been known to come in shapes such as square, hexagonal, and even triangular. And even on one panel screen, the holes can be different size. Such as NOV Brandt VSM300 series screen. Shaker screen frame is also related with shaker screen price

Wire mesh of screen panels

We know wire mesh or screen cloth is important part of shaker screens. So the mesh is another critical feature of shaker screens just like thread is woven together to create cloth, metal wire can be woven to create a metal cloth. Screen mesh has evolved over many years of competitive screen manufacturing resulting in very thin yet strong cloth designed to maximize screen life and conductance as well as to provide a consistent cut point.

Different shape of holes on screen cloth will affect screen efficiency or performance so the API designation will be different.

To increase the conductance of a mesh screen you have to minimize the amount of material in the way, this is done by either reducing the wire diameter or weaving the cloth to produce rectangular openings. Rectangular openings increase the screens conductance while minimizing the effect on its cut point where as square openings provide a more consistent cut point but offer a lower conductance. Cut point, conductance can be tested in special unit with professional device

We can’t mark our screen panel as API RP13C standard if we don’t test the Aipu shaker screen by professional party. The screen mesh size is a bit different with API size. Since API size designation will include the cut point, the conductance, the non blank area.

Shaker screen life

Evaluate screen panels quality, screen life is first issue to consider. To maximize screen life most manufacturers build their screens with multiple layers of mesh over a very sturdy backing cloth to further protect the cloth against solids loading and wear.

The multiple layers of screen act as a de-blinding mechanism pushing near sized particles, which may get stuck in the openings, out of the mesh reducing blinding issues and keeping the shaker screen surface available for use.

Although the performance of these shaker screens is quite impressive the only way to truly gauge the performance of any screen is to try it out and collect comparative data of your own. Under different working condition the same shaker screens will reflect different performance. Please do involve all issues when select or level the shaker screens

Trackbacks & Pings

  • API Shaker screens designation and features :

    […] Shaker screens conform to API 13C designation including the cut point and conductance. To be API RP 13C compliant, a screen must be tested and labeled in accordance with the new recommended practice. The tests describe a screen without predicting its performance and can be performed anywhere in the world. Internationally, API RP 13C will become ISO 13501. […]
