Net,
Any where that you have dry dust, you are at risk of combustion. Wood burns, dust "combusts!"
When I sand my wood Gym floors, I fill my vacuums up with already dry dust from the floor, dry it further with heat from sanding, and once in a while I smell a smoldering from my vacuum tank. Fires are not uncommon in my business. When we used to use vacuum bags they usually never caught fire until I would disconnect them from my equipment and let them set down.
The finer the dust the more combustible it is. On my final smooth sanding I have to be very careful that the dust is removed from the building quickly and never left in the building over night. I am assuming because the KDS can grind finer dust than any other grinder, it can also deliver a better fuel for dust burners and probably much more dense pellots.
As I once shared, a while back I used to call facilities that used grinders and talked about the KDS machine. Their answer was nothing against the KDS, just the overwhelming cost. They did not need the fine screen dust that the KDS delivers.
