Grinding Heads Drive System
The grinder comes equipped with Dual Drive Technolo-
gy™. As the grinding discs are driven by the large mo-
tor via an internal belt, and because the belt is sealed
inside the machine, there is no maintenance regarding
this drive system until a major service (belt and bearing
replacement) is due. This is typically following 12-36
months of operation.
Planetary Drive System
The second component to the Dual Drive Technol-
ogy™ system is the planetary head drive system which
is powered by the secondary or small motor and
gearbox arrangement. This system is on the outside
of the machine and will require routine maintenance.
The planetary drive system can be seen as illustrated

IMOPRTANT!
Lubrication of this system will cause dust to
build up in chain ring and drastically shorten
the life of both the chain ring and planetary
drive sprocket.
Diagram 1. Planetary Drive System
Beneath the gearbox and concealed by the mounting
brackets and machine cover, there is a planetary drive
sprocket situated on the output shaft of the gearbox.
This planetary sprocket engages with the chain ring
(also located beneath the machine cover) and
together form the main drive mechanism for the plan-
etary drive system. This system is a dry system (i.e. it
is not required for there to be lubrication between the
planetary drive sprocket and chain ring), to allow any
dust that may come into contact with the chain ring to
fall back out again.

1. Planetary seal
As the chain ring and planetary drive sprocket are
located beneath the cover of the machine, yet on the
outside of the machine, there lies the potential that
they can be exposed to dust and other debris created
during the grinding process.
To prevent this as much as possible, a planetary seal
has been installed to stop dust and other particles from
coming into contact with the planetary drive mecha-
nism.
