So, the first reason your sieve isn’t producing the results you expect is that your sieve could be clogged.
Over time, your sieve is going to suffer wear and tear. This is unavoidable and is a natural part of the process. But there are things you should be doing to minimize that wear and tear.
It is possible to have particle build up on the mesh of your sieve. The particles can stick to the wires which will actually change the opening size of the mesh by clogging the sieve.
The best way to prevent your particles from clogging up your sieve is to clean and maintain your sieve properly.
We have an article that covers all the proper ways to clean and take care of your sieves. There are specific methods you should use when cleaning your sieve as well as some dos and don’t.

The second reason your sieve may not be performing up to your standards is that it is out of spec.
The screen on your sieve is made from wire mesh. That mesh is what takes the impact as your particles are being sieved.
This impact during testing can cause the wires to stretch and tear.
The mesh opening sizes of your sieve are extremely important to your testing process.
When the mesh openings start to change sizes or get damaged, your testing results can be impacted.
This can affect your quality control, the amount of material wasted, and it can result in you spending extra time to measure and problem solve.
