Auger Samplers

Auger Sampling Systems are utilized to sample stationary bulk materials from trucks, railcars, barges, and stockpiles. 

These samples are utilized to establish the commercial value of the coal or to allow the operator to blend coals efficiently.

The PSI auger is designed to mechanically extract a vertical column of coal from the vehicle as it passes under the auger. The PSI Auger Sampling System is a heavy-duty device and has been proven to efficiently extract run-of-mine coal sample increments.  Even under the most demanding field conditions, PSI has proven that the equipment can maintain a consistent availability of over 99% when properly operated and maintained.

The PSI Auger Sampling System is available with a 12", 16", or 20" Auger Assembly.

In applications where there is a high volume of vehicles to sample, PSI provides secondary processing capabilities which are utilized in conjunction with the auger sampling system to allow the auger increments to be processed to a manageable size.

A PSI secondary processing module includes a sealed receiving hopper, primary belt feeder, sample crusher, secondary sampler, sample collector, and reject handling system.

PSI provides optional sample collector sizes to collect save samples with up to 20 sample containers each.  Multiple sample collectors can be arranged to include up to forty 40 sample containers per system.

Automated Auger

The PSI Automated Auger Sampling System is the solution to provide accurate, randomized, and completely unattended truck sampling.  The PSI Automated Auger Sampling System is typically integrated with the truck scales and is capable of weighing and sampling as many as 600 trucks per day without utilizing any operators.  The Automated Auger Sampling System's PLC controls the sampling system operation, randomly positions the truck for sampling, and automatically indexes the sample collector.

The initial cost for the automated auger is higher but the unit quickly makes a significant return on investment when you factor in the labor cost savings.  In most cases, the cost savings from the daily operational efficiency will return the initial investment in less than five years.

Stationary Auger

The PSI Stationary Auger Sampling System is a permanently installed auger sampling system.  The sampling system is typically utilized in high volume locations when multiple sample collectors are required.  The stationary auger sampling system will accommodate two full size 20 sample collectors and is provided with a full size control room.  The stationary auger is available with a 12”, 16”, or 20” diameter auger assembly.

The enclosure is a heavy-duty conventional structural steel building with an architectural siding enclosure.  The system is installed on a conventional concrete pier and footer foundation with a concrete floor.

If incorporating an online analyzer into the auger sampling system scheme is required, the PSI Stationary Auger Sampling System is the preferred choice.

Modular Stationary Auger

The PSI Modular Auger Sampling System is the preferred choice when a cost effective stationary auger sampling system complete with a full size control room is required.  The system is manufactured in modular units allowing it to be easily dismantled for future relocation as required. 

The system is installed on a concrete pier foundation which isolates the crane operation from the processing unit.  Separating the crane operation from the processing unit greatly decreases vibration in the operator’s control room.  The modular sampling system utilizes 480V power and is complete with a stationary crane mounted auger, sample processing station, hydraulic power unit, and reject handling system.  The processing station is available with an 8, 10, 12, or 16 container sample collector.  The reject handling system allows the reject to be discharged to the ground or back onto the truck being sampled.

Portable Trailer Mounted Auger

The PSI Portable Trailer Mounted Auger is an auger sampling system with the capability of sampling approximately 240 trucks per 8-hour shift and still be considered a mobile auger sampling system.

The sampling system is a self contained unit that is powered by 480 V power.  The unit is complete with a crane mounted auger and operators cab, sampling processing station, hydraulic power unit, and reject handling system.  The processing station is available with an 8, 10, 12, or 16 container sample collector. The reject handling system allows the reject material to be discharged to the ground or back onto the truck being sampled.

Truck Mounted Auger

The PSI Truck Mounted Auger is the solution to your auger sampling requirements when you need immediate auger sampling capabilities.  The truck mounted auger is mounted to the frame of a medium sized flat bed truck.  The crane and auger operate from a transmission mounted PTO and hydraulic pump which eliminate the requirement of electric power allowing the auger to be truly mobile.  The operator extracts auger increments as required and collects them in the bed mounted bagging hopper.  PSI truck mounted augers have a 12” diameter auger which collects approximately 200 pounds per increment.  The 200 lb increments are quartered at the top of the auger and approximately 50 pounds is collected in the bagging hopper.

The truck mounted auger is easily mobilized and a good tool for stock pile sampling as well as the sampling of trucks and railroad cars.

If the number of samples collected is not feasible to manage by hand, the truck mounted auger can be paired up with a PSI Remote Operated Processing Station.  The processing station is complete with a primary feeder, sample crusher, and secondary sampler.  The processing trailer is self contained and operates utilizing either 230 or 480 V power.

PSI typically has truck mounted augers and processing stations available for short and long term lease.
