GeT The m osT from Your rem co crusher
A long time REM co customer , user of A Sand M ax in the cAribbeAn ,
hAs experienced enough business growth in recent yeArs thA t they needed to build A new plAnt .
Back in 1997, this major producer purchased and installed a REMco model 9000 SandMax
with twin drive of 250 HP motors. At that time, the SandMax was installed to produce
concrete sand that could not be made in their two existing 48” cone crushers. When they
added the 9000 SandMax , sand production doubled and this higher production, met
their requirements for over a decade.
During that time, growth of the Caribbean market for sand and other good shape aggregates
has more than doubled, putting a growing production demand on the original crushing
plant. As the premier supplier of quality sand and aggregates on the island, the REMco
user studied the problem with careful consideration for new environmental regulations,
overall business logistics, and their future sand and aggregate needs.
This carefully studied decision led to the building of a new plant which would double the
concrete sand production capacity of the original. But uniquely, to control cost, the new
plant incorporated the existing equipment which is to be moved from the original plant to
the new site that was chosen with great care for environmental impact on the surrounding
area. The challenge was to maintain production while the engineering, fabrication and
construction of the new plant took place. With a timetable of six months to complete the
(continued next page) –!–Continued
move without interruption of production, careful planning was required as well as
purchasing and installation of the new crushing and screening equipment. A key
component was the need to use a proven performer to minimize the possibility
of any startup delays or production losses in achieving the needed doubling of
production of sand. A REMco 2011 model 5080 SandMax , again with twin 250
HP motors, was selected and has now been installed. This was done because the
REMco SandMax was viewed as a reliable performer to produce quality sand,
at the lowest crushing cost.
Figure 1: Original REMco model 9000
SandMax was installed in 1997, shown
working alongside a 48” FC cone crusher to
augment concrete sand production.
Figure 2: In June of 2011, the original 9000
SandMax after many years of service, was
retrofitted and updated to continue the concrete
sand production at the original plant. Later it will
be moved to the new plant to work with the 2011
model 5080 SandMax .
After the old 9000 SandMax was
retrofitted in the field to the new model
5080 standards with the additional new
500 HP REMco 5080 SandMax unit,
production rate will improve to over 300
tons per hour of high quality concrete
sand. The new plant design incorporates
only the new REMco and the refitted
model 9000 in the sand production
circuit, as the cone crushers from the
old plant are not to be used in the new
plant. This decision further improves the
sand quality for grading and finishing
characteristics as there will be no cone
crusher product in the sand.
In years to come, the Caribbean demand
for manufactured sand will continue to
grow, and the REMco SandMax
units from this installation as well as from
several other REMco SandMax
crushers on a number of the Caribbean
islands will meet that demand.
Figure 3: This 2011 REMco model 5080
SandMax complete with REMco installation
kit will soon be producing more high quality
concrete sand in the sunny Caribbean.
Repeats a Good Decision –!–Unfortunately, crushers do wear out. Typically, VSI crushers after 10, 15 or more years of service
may require extensive repairs to make them serviceable. REMco repairs and rebuilds all brands
of VSI crushers. However, with a REMco unit, because of its basic design, these repairs can be
done such that an old crusher can have the features of a new crusher after repairs. For example,
an older REMco Model 9000 or Super 100 , either single or dual drive machine, may
now require extensive repairs. Typically, these repairs involve the feed areas, crushing chamber
and discharge areas of the crusher. Usually the motor mounts, support frame, drive assembly with
motors and other components may be completely serviceable and can be reused in their existing
In many of these instances, depending on the degree of repairs required, the old crusher body
can be discarded and replaced by a new Model 4060 or 5080 crusher body. The end
result is that the crusher owner receives a brand new machine instead of a repaired, old machine.
This type of repair receives a new crusher warranty and costs the user less than shop repairs or
approximately half of what a new crusher would cost. This work can be made in the field in 1 to 2
days versus waiting weeks for the old crusher to go to the repair shop and be returned.
By doing this, the final crusher can have a hydraulic hopper system, convert from grease lubrication
to oil lubrication and incorporate the latest safety systems and other features of the 2011 / 2012
series of REMco crushers. If this type of repair is necessary in your existing REMco unit, contact
your local representative or REMco direct.

NOW BACK BY POPULAR DEMAND!!! A buzz has started up about REMco’s Service & Maintenance
School … So we’re bringing it back for all those who were unable to attend last year.
This Service & Maintenance School is specifically designed for the folks that work on and with REMco VSI crushers.
We will discuss in depth how the crusher works, how to make it perform at optimum levels, how to reduce
maintenance time, reduce costs through proper parts selection and more. We’ll get down into the nuts, bolts
and oil of the machine, from the feed distributor in the hopper to the discharge hopper at the base, everything
in between and much more.
