Ramsey Primary SweepType Sampling Machine
Weighing and Inspection
The Ramsey Model SWAX-7000 SweepType Sampling Machine offers an economical, simple means to procure arepresentative sample directly from a mainstream of material. Direct increments areobtained from in-motion, horizontal orinclined conveyors.
With over 700 units in service worldwide,the SWAX-7000 Sampler can be used asa stand-alone sampling device to extracta cross belt cut to a sample container, or as a primary (first stage cutter) in a multistage mechanical sampling system.
The Sweep Type Sampling Machine hasbeen subjected to rigorous, in-the-fieldtesting, teaming with an extensiveresearch and development program. The Model SWAX-7000 machine meetsASTM & ISO Specifications. Parts and service on all Ramsey sampling equipmentare available on short notice fromMinneapolis, Minnesota.
The Model SWAX-7000 machine is ideallysuited for sampling of coal, limestone,sand, crushed rock, gravel, ferrous andnon-ferrous ores. Because of installation
ease, the Sweep Type sampler is easilyretrofitted to existing bulk material beltconveyor systems. Backed with over 40 years experience in engineering and manufacturing, Ramsey sampling systems are recognized worldwide asthe finest available.
For complete information on this and other sampling systems and equipmentavailable, please request Catalog No. 100.000.
An economical, simple means to procure representative samples.

Features and Benefits
• Compact design is well-suited for low headroom installations.
• Ease of installation results in modest installation costs.
Mounts directly to existing or new conveyors. No transfer
point is required.
• Rigid construction of tubular structural steel maintains
positive alignment.
• Direct drive for positive stopping whether the belt is loaded
or empty.
• Skirtboards on sampler prevent material spillage.
• Cost efficient. Small primary increment means smaller, less
expensive equipment in the reduction stages of system.
• Non-contact proximity switches for start-stop control.
• Replaceable steel brushes and urethane wiper assure fines
will be removed and included in representative sample.
• Samplers counterweighted to eliminate high eccentric loading
on 36" and larger belts.
System Operation
At pre-determined intervals, the Ramsey Model SWAX-7000 sampler
rotates a full 360° through material on a moving belt. A complete
cross section primary increment is taken. The sample is directed
down a chute onto a primary belt feeder. The feeder meters the material
into the crusher. The crusher reduces the product to required size
without the loss of fines, while keeping moisture loss at a predictable
and repeatable level. The sample is then split using a secondary
sampling machine. These machines are selected to meet each sampling
requirement.
Finally, the sample is collected in a dust/moisture-tight container. The
reject material from the sampling system is returned to the mainstream
of material.
Several methods are available as dictated by operating requirements:
gravity fall, screw conveyor, belt tube conveyor, or bucket elevator.
Self-Contained Sampling Unit (S.C.S.U)The Ramsey S.C.S.U. provides a
modular approach to sampling. It’s available
with all required equipment (except the
primary sampler itself), pre-mounted and
wired, and ready to hoist into place onto a
concrete pad. The S.C.S.U. and Sweep Type
Model SWAX-7000 Primary Sampler can be
placed at any convenient location along a
suitable conveyor. It does not require an
expanded transfer tower or expensive
sampling tower, which minimizes installation
costs. Optional equipment available: roof
with trusses, hinged side panels (insulated or
non-insulated), ventilation fan, and heating.
Features
• Utilizes Primary Sweep Type
Sampling machine
• Completely pre-assembled structure
for ease of mechanical installation
• Equipment completely pre-wired
to PLC control panel and motor
control center (Optional)
• Full range of options including a
totally enclosed module, heat
and ventilation
