Tietjen Security Slide

Tietjen Sercurity 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.

Operation - Phase A

Hopper filled: The ground material in the metering screw and hopper blocks flame propagation between the hammer mill and conveyor system.

Operation - Phase B

Hopper empty: After a preset time the slider closes automatically (controlled by empty indicator, timer and Pneumatic guard). The safety slide blocks the flame propagation between hammer mill and Zconveyor system.
