Among the features which make the LMC Roca
Series Stoner superior to all other Stoners are the step
deck and the air operated rock discharge.
The step deck feature allows the product to
maintain traction with screen; therefore the deck does not
lose its ability to carry product because of slickness or
build-up. The step deck maintains carrying capabilities unequal
to woven or perforated decks used by other stoners.
The air operated rock discharge feature allows
you to make a distinct separation between rock, dirt balls,
glass, metal or any other foreign material that is heavier
or more dense than the product. This works by adjusting the
static pressure in the rock discharge deck cap. Adjusting
the static pressure in the deck cap allows the operator to
automatically make a distinct separation of the accepts product
and the rock or denser product.
