Stationary Auger Sampling System
The samples are retrieved using the hydraulic boom with telescopic arm with Auger assembly. Unique design ensures retrieving samples from any point any depth inside the coal trucks or rail wagons using the methods of "stationary auger sampling system", which ensures fast and representative samples.
A stationary auger sampling system uses a vertically oriented screw within a tube to penetrate the material and collect an increment from a truck, rail wagon or open-top container. The collected increment can be discharged directly or transferred to a sample-preparation system for crushing, division, packaging and traceable identification. If the full auger increment has to be collected, the collected samples will be discharged. If the auger increment is to be split, the material passes from the top of the Auger tube and through a fixed splitter where the rejection portion falls back in to the Truck Or Rail wagon.
Once the Auger increment being collected in the Spool, the auger is maneuvered to a sample bin. There could be multiple bins for collection of designated samples which again can be sent for further subsequent sample processing with the help of primary conveyor, primary crusher for size reduction and may be for secondary conveying with further crushing with rejection handling and sample packaging in small quantity for Laboratory processing. Drawn sample can be packed in a auto-operated packing machine. Sample can be packed in a tamper proof pouch with a barcode to avoid human intervention and futher tracking.
stationary auger sampling system are incorporated into a wide variety of applications but are most frequently used for Truck beds, Rail wagons, open top shipping containers. Bulk materials that are frequently handled includes coal, coke, crushed ores, manganese ores, pallets, Coal Tar etc.

Mobile Auger
The Mobile Sampling Equipment (MSE) is the latest innovation from Rexline Engineering Indonesia. REI has been working with the schematics and small models and finally got the opportunity to developed the existing model complete with bin management system. Mobile Auger is specially designed and manufactured for the purpose of collecting samples from trucks/wagons for representative testing & the quality of any mineral by using a mechanized Auger.
The auger and sampling sequence are engineered to the contractually applicable sampling standard and the material's nominal top size. Compliance is confirmed in the approved design basis and sampling-system documentation. The equipment is mounted on a hydraulically operated retractable arm. It can be raised above the rail wagon and then lowered to collect the designated sample. The rotary motion of the Auger enables it to go down in the heap up to the desired depth and pick up the sample as per need. The MA's motor is reversed and the sample is collected in the desired bin. This complete assembly is mounted on a mobile unit that can easily approach towards the rail-wagon to be sampled.
A true sample of a truck, railcar, open top shipping containers, or any other bin type of containers of coal or any minerals can only be obtained prior to unloading. Once it is unloaded, the individual load mixes with other coals, or minerals and loses its specific characteristics. This type of sample collecting device is one of the modern solution of sample collection at the entry point of Truck or Rail wagon, Auger is mounted on a vehicle and can be moved towards the truck and wagon to collect desired sample

Conventional Cross Belt Sampler
The Rexline Engineering Indonesia Conventional Cross Stream Sampler Is custom designed to be an Integral part of the main conveyor head chute which meets the client's specific requirements. The Cross Stream sampler is typically installed in new applications where large primary sample increments are required or space limitations exist prohibiting the installation of a Rotary Sweep Sampler along the conveyor. The REE Cross Stream Sampler is available with either an electro-mechanical drive mechanism or hydraulic/ pneumatic drive mechanism.
2-Stage Sampling System
The 2-Stage Sampling System ls the most common system arrangement. This arrangement includes a sealed primary sample receiving chute, primary belt feeder, sample crusher, secondary sampler, sample collector, and reject handling system (Screw Conveyor, Belt Feeder, or Bucket Elevator) The primary belt feeder feeds the primary sample increments to the sample crusher where the sample increments are typically reduced to a 4-mesh product. The product from the crusher is gravity feed to a Belt feeder where secondary sampler is installed which takes a secondary increment. The secondary increment is also gravity feed and stored in a sample container. The reject handling system returns the reject to the main conveyor for most installations.
3-Stage Sampling System
The 3-Stage Sampling System are also widely known as tertiary sampling system, is typically utilized with the Conventional Cross Stream Sampler which produces a very large primary sample increment and requires an additional stage of processing to reduce the sample to a manageable size. This arrangement includes a sealed primary sample receiving hopper, primary belt feeder, secondary sampler, secondary feeder sample crusher, tertiary sampler, sample collector, and reject handling system.
The primary belt feeder feeds the primary sample increments to the secondary sampler, the secondary sample increments are fed via the secondary feeder to the sample crusher where the sample increments are typically reduced to a 4-mesh product. bucket elevator The product from the crusher is gravity fed to a tertiary sampler which takes a tertiary increment. The tertiary increment is gravity fed to a save sample container. The reject handling system returns the reject from the secondary sampler and tertiary sampler to the main conveyor for.
Monitoring can be done through D.C.S.
Scoda system will help to monitor recent trend.
System can be operated through PLC.
Barcode can be generate and stick on sample pouch.
Screw Sampler
The Screw Sampler is designed to create an average sample from continuous extraction of dry non-sticky powdered material from a free falling flow of materials.
The continuously operating sampler is driven by a geared motor, coupled to a transport screw crossing the flow of material. The screw transports the extracted material to a mixing tank, where it is homogenized by mixer wings connected to the through going screw conveyor shaft. The sampler can be delivered with the drive unit installed next to the mixing tank.
Installation in silos or downpipes possible.
Different diameters for screw samplers available.
Sample quantities, runtimes and pause times individually adjustable thorough a control electrical panel.
Automated or manual sampling method.
Easy-to-dismantle version for simple cleaning.
The sampling screw rotates into the material flow, extracts a representative cross-section from the production flow and transports it into a sample vessel. An adjustable timer determines the sample quantity. Runtimes and pause times between two sampling operations are individually configurable. Before starting a further sampling process, the screw changes to reverse operation for a selfcleaning cycle. The product conveyed during the self-cleaning process is fed back into the production flow. The control of the sampler is normally conducted from a central PLC system but we also provide local control panels with or without a PLC. Downpipe: The sampler isinstalled between two flanges inside the downpipeSilo: The sampler is installed to a nozzle welded to a silo wall.
For contamination-free sampling.
Low-servicing requirement.
Size of the sample can be defined as required.
Immediately after sampling, sample falls into a bag or beaker attached to the discharge connection.
There is no chance of compact due to mixing chamber is there just after screw for abrasive and sticky material.
Vezin & Belt End Sampler
Vezin Sampler
Vezin Sampler is also known as Gravity Feed sampler is designed to collect the sample from free flow of a chute for any type of material.
This type of sampler design requires very little space and collects representative samples from sloped gravity chute areas. When activated, a sample cutter pivots through the product stream, sweeping a complete 360-degree arc, collecting a true cross-cut sample. Sample cutter is parked away from the stream of material and is sealed when not sampling.
Belt End Sampler
Belt End Sampler used at the discharge point of any conveyor belt to collect the representative sample. General use of this type of sampler is To and Fro type.
