Primary Sweep Type Sampling Machine

Primary Sweep Type Sampling Machine

An economical, simple means to procure representative samples.
Model SWAX-7000 Sweep Type Sampling Machine offers an economical, simple means to procure a
representative sample directly from a main stream of material. Direct increments are obtained from in-motion, horizontal or
inclined conveyors. With over 700 units in service worldwide, the SWAX-7000 Sampler can be used as a stand-alone sampling device to extract a 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 has been subjected to rigorous, in-the-field testing, teaming with an extensive research and development program.  The Model SWAX-7000 machine meets ASTM & ISO Specifications. Parts and  service on all Ramsey sampling equipment are available on short notice from Minneapolis, Minnesota. The Model SWAX-7000 machine is ideally suited for sampling of coal, limestone,sand, crushed rock, gravel, ferrous and non-ferrous ores. Because of installation ease, the Sweep Type sampler is easily retrofitted to existing bulk material belt conveyor systems. Backed with over  40 years experience in engineering and manufacturing, Ramsey sampling systems are recognized worldwide as
the finest available. For complete information on this and other sampling systems and equipment available, please request Catalog No. 100.000.

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
• 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.
