First look at the type of industrial applications (i.e. food, pharmaceutical, mining) of a studied equipment to see if its manufacturer is strong in the same industry application as the one required for the project; and if the manufacturer has experience handling similar materials as given for the application. If the material is atypical, then pilot testing could also be required.

Test house, manufacturer and industry is a TEAM where together everyone achieves more. Lost time and trust cannot be regained. There is no shortcut. Each process is unique and copying may not solve problems but may create some. The common errors always lie in different objectives of test house [operator], manufacturer and industry.

Look for the separators that operate at slow speed to minimize the breakage of material and wear on separator parts. Be sure the manufacturer has the experience and provides the advice and support you need to keep in production if the feed stock changes or other problems affect your separation.

The output capacity is very different of the hydraulic capacity of the high speed separator. In some applications output capacity can be the 50% of the hydr. cap. but the process requires longer retention times inside the separator to achieve the separation.

Yes - do not use the mesh system, do size your material and analyze the results. The system is vague and easily manipulated to "fool" customers into thinking they are getting efficient screening when they are not.
~Bob Grotto, President/Ceo, Mamaroneck, NY
Screening and crushing technology has improved in only the last few years. A screen is a screen is no longer the case, the industry has specialized.

Run tests at the manuf. factories lab in advance with the real product, and let them give you a keen offer with guarantees on the yield.

For products with a acid pH, always check the performance of the sieve material in the screener.

Don't go too small, make sure you figure in peak flows so as not to flood the system.
