Tietjen Security Slide
With an empty feed hopper metering, Tietjen security slide Ex-S disconnects the mill feed. The automatic shutter is especially important for preventive explosion protection right after the conclusion of a milling process. The pneumatically activated slide closes automatically at power failure by a compressed air reserve in the attached compressed air tank. The compressed air supply is monitored.
