1. Introduction. Rice mill, which generally consists of a stationary hopper and drum, a rotating spiral conveyor and shaft running along the axis of the drum, is one of the typical stirred mills and has been extensively used for rice milling in food processing [1,2].Rice milling is to remove the external bran, meanwhile it can cause unexpected breakage, under-milled rice …

The Ballbar test will measure any deviation the machine makes from a perfect circle, recording data as the two axes work together. Errors such as backlash, level/squareness, servo mismatch, reversal spikes, vibration, stick slip and other problems can be determined. Users can be useful in determining what feedrate delivers the best accuracy by ...
