Barrier Seal System For Bag House Dust Collector

Dust from superheated (2500 degrees) limestone rock is drawn through a kiln into a “bag house.” The reducer drive screw conveyors feed into a central repository. The fine dust that is generated penetrates the seal system in the competitor’s units causing an excessive number of failures to occur.

Browning® Product Solution

The solution included utilization of the patented barrier seal system from Regal. This combines a v-ring face seal, grease filled labyrinth and rotating outer flinger to help provide protection against contamination and oil seal damage.
