Maintenance
Used correctly, the machine is an extremely low-main-
tenance and reliable.
This section covers the general maintenance items
that need attention on a periodic basis.
There are three main mechanical items to check:
1. Grinding Heads.
2. Planetary drive system.
3. Planetary seal.
Grinding heads
There are 2 different grinding head options:
11. Conventional / Demolition heads—designed for
heavy duty preparation grinding where an extremely
robust system is required.
2. Spring steel head system—designed more for fi nish-
ing or lighter grinding applications.
CONVENTIONAL/DEMOLITION HEADS
The below diagram illustrates the main parts compris-
ing this type of grinding head.
1. Head mate
2. Head plate
3. Head lock
4. Head spring
The interrelation between the above four components
enables a dynamic system which is both robust and
fl exible.
The head pins are fi xed to the head plate giving rigid-
ity and stability. The head mate is situated above the
head plate and is held in place by a series of holes
– head pin holes.
1. Head mate 1. Head plate
2. Head pin hole 2. Head pins
Between the head plate and head mate are 3 white
silicone springs which give shock absorption and fl ex-
ibility in the system.
The head pins are able to move within the head pin
holes, creating a shock absorber type system similar to
that in most motor vehicles.
Over an extended period of time, the head pin holes
wear open. Along with this, the head pins wear and
reduce in diameter. This combined wearing of the two
creates excessive movement or “slop” within the grind-
ing heads. This “slop” will eventually cause vibration
whilst the machine is operating.
Routine checks for slop in the grinding heads are
recommended. Life expectancy for grinding heads can
vary between 6 and 12 months depending on amount
of usage.
Replacement heads are available and simply bolt into
place when the old ones are removed
