Several geared motor units have been
installed by GSM at a recycling plant
in southern England to reduce downtime
and improve efficiency. The
plant has been converted from a
hydraulic drive system with a very
large power pack and complicated
hose and valve system into a clean
and simple electrified version with
energy savings.

On the site an incline conveyor is
fed material from a ‘Walking Floor’
Fines conveyor.When hydraulic,
varying the flow to a fixed
displacement motor and gearbox
meant this was variable speed. The
customer was anxious to retain the
variable speed function and so a shaft
mounted planetary gearbox with
mechanical variator and electric
motor was supplied. This means that
the operator is able to simply adjust
the feed of material on to the main
incline conveyor while the conveyor is
operational.
