Great Western maintains a complete testing laboratory to evaluate product samples and make equipment recommendations.
 

There is no charge or obligation for our laboratory service.   Companies can submit materials to the testing lab which uses the Great Western Sampl-Sifter to replicate the performance of their full scale horizontal gyratory sifters. Testing will determine how your product handles and what difficulties might be encountered due to particle size distribution, particle shape, bulk density, moisture and oil content, and the possibility of static charge. Test results state area requirements and serve as a guide in determining the optimum equipment size and specifications for sifter speed and circle, sieve depth, throat size, side opening, pan slope, and the number and type of cloth cleaners to meet your process objectives.
