Autogard Series 820 Torque Limiter for Mining Conveyors

Mining / Conveyors Case Study
Industry:
Mining
Application:
Conveyors
Rexnord Autogard Torque Limiters
Keep Material Moving
Problem / Requirement:
Operational jams or sudden
stops without reliable
overload protection result
in low production rates and
high costs and downtime if
problems occur
Mining conveyors move materials from mines
to further processing areas as quickly and
efficiently as possible. The distance from the
mine to processing areas and beyond can be
significant.
Solution:
Autogard 820 torque limiter
Reliable power transmission is critical in this
application for the daily requirement of driving
the conveyor. The power transmission system
must also be protected from the inevitable jams
and sudden stops on the conveyor line.
Result:
Efficient and durable conveyor
drive with minimal running
costs and downtime in the
event of a jam or sudden
stoppages
The Autogard® Series 820 has been designed to
meet the emerging need for overload protection
on very high torque drives in heavy industry
applications. The torque limiter is designed
using a modular principle which enables the trip
torque capacity to be set to virtually any value.
Individual torque limiting elements are mounted

around the periphery of the torque limiter. The
torque capacity is then dependent upon the
radius at which the modules are located and
the number used. Each module is set to give
repeatable and reliable disengagement in the
event of an overload.
