Perhaps you would like to enhance you roller mill investment with a custom-designed upgrade by Lehmann Mills. New Features can be incorporated into older mills or new mills.

Anti-Backlash, motorized machine screw actuator roll adjustments

Powered through worm gear reducers, 1/4 H.P. motors are coupled to actuator roll adjustments at each end of the feed and take-off rolls, controlled by "Pressure", and "Pressure Release" push buttons, which are mounted in an operator's control panel.

Four programmable digital read-outs provide the roll settings of the feed and take-off rolls, allowing precision adjustments of the roll positions in increments of .001", at the push of a button. A field programmable indicator controls roll travel limitations. A non-volatile memory retains the programs in the event of a power interruption.
