follow the quarry face, as well as use
them at both of our Cherenzia quarries
and at other sites.”
On the level
In addition to a shortage of sand, there
are virtually no level construction sites
left in Rhode Island and Connecticut.
Contractors are having to build on
hilly, rocky terrain they call “ledge.”
Typically, the contractor has to blast
the rock – mostly granite – then grade
the land for residential and commercial
construction projects. This leaves a lot
of shot rock to dispose of or put to use
in some way.
The best way to handle this situation is to crush the shot rock on site

and use it as base materials, usually also
on site. Hauling it away to be dumped
or crushed would be an added expense,
and there are few, if any, dump sites
available.
Crushing on site provides opportunities for Cherenzia to use the portable
1000SR and XR400 either individually
or together in three ways: 1) crushing at
their own excavation, demolition and
construction jobs; 2) contract crushing
for others; and 3) as rental machines to
various contractors.
The XR400 is used largely to crush
overburden as base fill. It also enables
the recycling of concrete rubble and
construction/demolition debris, since
the machine design includes hydraulic overload protection. The jaw has a
hydraulic release feature that opens up
if anything too hard – such as oversize
tramp iron – gets in it. The jaw opens
up, drops the hard material onto the
discharge belt, then closes up again
and goes on crushing. This eliminates
shutting down the crusher to get the
jaw unlocked and the iron out, which
can take a lot of time.
