Test sieves will perform accurately for many years with proper care and maintenance. To make your test sieves last longer, you need to carry out cleaning carefully and use the following tips provided below.
When the particles are lodged in the woven wire mesh, they should be cleaned out as soon as possible. They can enlarge the mesh holes, in turn, affecting the accuracy of the test results.
It is recommended to use a special sieve brush to clean the mesh using a gentle circular motion from the underside. Be aware that sharp objects might damage the mesh.
It is preferable to use a nylon bristle pan brush with the bristles cut to a length of approximately 25 mm (1″).
Brushing should be avoided on sieves finer than 150 microns (No.100), this can cause the wire mesh to loosen.
Ultrasonic cleaning is a good way to clean the fine mesh or remove the lodged particles. After this process, ensure that the test sieve is dried thoroughly before use.
We also recommended users to
Avoid putting heavy loads onto the sieve surface. Always make sure that the volume of the sample is not going over the maximum permitted volume for each aperture.
Organise the stack of sieve with consideration to the steps in aperture sizes , especially when using a sieve shaker. Make sure that there is a larger aperture size sieve nested above the fine mesh sieves. This will help to catch the bigger samples before they land on the finer mesh surface.
Average recommended test sieve calibration should be carried out every 12 months. In some cases, every 6 months depending on the level of usage. A weekly check is advised to obtain consistent results. Calibration results will be able to indicate whether the sieve is still accurate to use or it is time to replace with a new one.
If you have chosen to use Glenammer test sieves, congratulations! A satisfied customer recently commented “Glenammer test sieves last three times longer than other brands on the market”. Glenammer offers a life-long warranty against any manufacturing defects.
Glenammer has made the following efforts to produce long-lasting test sieves:
– Material: we choose to use high-grade stainless steel to produce our test sieves. Stainless steel is a more durable and stable material for various laboratory testing applications.
– Label: we have applied 3D laser technology to generate a permanent metal cut-in label, which will carry the product information on the frame for the whole lifespan.
– Reinforced Mesh: For 300 mm diameter (and above) test sieves with apertures 90 micron and under, we have a supporting layer underneath the initial mesh to ensure these fine test sieves last longer.
