Browning TorqTaper Plus Aggregate Conveyor Solution

A major aggregate quarry has used a competitor’s “AGMA-size 215” shaft mount on this application in the past. Two years ago, the quarry had to replace this unit after excessive oil was leaking from the input and output seals. The quarry also noticed metal filings in the oil, indicating that the internal gears were also wearing. A local repair facility provide a rebuilt reducer at
approximately half the cost of a new unit. After only 8 months the quarry noticed similar problems with the rebuilt shaft mount that was installed.

Browning® Solution

Browning 215SMTP15 reducer (and accessories) purchased due to patented barrier seal system, quality gears, higher torque ratings, tapered roller bearings and warranty.


Processing system where aggregate is loaded onto a flat conveyor belt and transferred to an inclined conveyor before it is re-processed through screening and crushing applications. Significant amount of airborne contaminants present in application. Some shock load when material is dropped onto flat conveyor belt. 

Solution Type

Maintenance cost savings.
