How the unit works
Grinding
methods
The 8550 ShatterBox comes pre-loaded with a basic grinding method that can be
used as is, or can be customized. All grinding methods can be saved, renamed,
deleted or copied, just like computer files. Only the preset method is protected to
avoid accidental overwriting.
Each method allows the user to configure two grinding stages, each with their own
speed (in RPM) and duration.
Door operation
Once a grinding dish has been installed and the user intends to start a grinding
method, he or she must first manually close the door by sliding it all the way up,
until it locks.
If the door was closed by mistake and the grinding method has not been started,
the user can still un-lock the door through the LCD interface.
The safety door will automatically slide open again at the end of a grinding cycle.
Clamping the
dish
When the safety door is open, the user can slide a grinding dish inside the unit,
where a recess will position it. The user then closes the door, which locks.
With the door locked closed, the unit can now receive the command to start a
grinding method. The unit will then check for the presence of a dish, and
automatically clamp it in place.
Grinding
motion
The dish will now be moved by the main motor in a horizontal circular motion. There
is no rotation, as the dish remains in the same orientation while being translated
about a circular path.
The circular motion of the dish is automatically counterbalanced by a mechanical
system, ensuring minimal vibration transmission and noise generation.
When the grinding cycle is complete, the grinding motion slows down to a stop, the
dish clamping system is released, and the safety door opens, so that the user can
slide out the dish, containing the ground sample.
