Questions You Should Ask About Sieve Screen

Many industries use wedge wire sieve bend screens to separate dry or superfine particles during manufacturing or for wet washing silt and dirt from bulk aggregate reclaimed from mining or agricultural processes. The basic design specs of different types of sieves will always drive your initial selection of a sieve. These include the frame size and the mesh or screen opening size. Both of these depend upon your particular process equipment and the size of the particles to be screened.

However, not all sieves are equally built. Here are some “Should Ask Questions” to help in choosing a wedge wire sieve manufacturer that provides the highest quality sieve screen assembly, that can be used for many applications and serves a wide range of industries.

What is the best material for mesh construction?

A stainless steel sieve frame and woven mesh are the preferred material of construction for high-quality construction. Stainless steel offers a high degree of corrosion resistance which is critical with industries that are introducing moisture or caustic fluids into the filtering component. Stainless steel sieves will also last longer and will not add contamination into the filtering process. Tin plated steel and brass frames are the less optimal choice.

What are wedge wire sieve sizes?

The size of the openings within the wedge wire sieve screen is critical to proper functioning and filtering. Choose a manufacturer that offers a wide range of opening sizes from 4” mesh (100mm) to 635 mesh (20um). The frame which supports the woven mesh cloth is available in standard U.S. sizes including 3 inch, 8 inch and 12 inch. International frame sizes are standardized at 100mm, 200mm and 300mm. The mesh wire diameters are also considered and can range from 8 mm for 125-mm mesh to 0.020 mm for 20-µm mesh. 

Generally speaking, the size of wedge wire sieve screen can be customed as your application.

What to consider in a quality sieve frame?

The durability of your test sieve will depend greatly on the quality of the frame and how the mesh cloth is mounted and secured. 

What is the price range for wedge wire sieve screen strainer?

There are many factors that contribute to the final cost of sieve bend screen, including the type of sieve, the alloy material, the mesh and sieve frame sizes, and whether the assembly needs to be certified. Wet test sieves will typically cost more than standard sieves. As the frame diameter and sieve height increases, so will the price. The main factors that drive the price of test sieves are the quality of the mesh material and the size of the perforations in the mesh cloth. The finer the mesh, the more expensive the entire sieve will be as they will provide a higher quality filtration.
