Where coal sampling by auger cannot be used (directly in the mine, extreme granularity), it is much more efficient to use this method to determine the quality of coal in trucks.
The advantage of this system is that the entire load of a truck can be measured by an online coal quality analyser for immediate information on the quantity and quality of a given fuel, and at the same time, a sample can be taken by an automatic belt sampler according to the standard (e.g., ISO, ASTM, GOST). This system can thus solve the customer's problem when it is not possible to design the sampling with a auger sampler for its parameters in such a way as to meet the required standard.
The truck dumps the entire load into the hopper with the crusher, the coal is crushed to the desired granularity and continues on the belt conveyor. An automatic belt sampler, designed according to the required standard, takes a representative sample for the laboratory, which can be used for commercial purposes. All fuel is also measured by an online coal quality analyser, which determines the quality and quantity of a given fuel in real-time. The fuel is poured into another bunker, under which a truck arrives for reloading.
Based on the results of the online analysis, the operator can instruct the driver to dump the load at a specific location/pile where fuel of that quality needs to be stored.

The auger sampling device is mounted on the positioning device which moves the unit to the chosen position. The sample will be taken in accordance with regulations from any place or depth of the dump truck bed. The auger will extract the material from the truck while performing primary division. The needed part of the sample is collected into the sample hopper and the rest is dropped back to the truck. After the hopper is full, the sampler returns back to the home position to discharge the sample into the chute of the processing line for further sample processing.
From the chute the sample is transported to the crusher to be sized down to 10mm. The processing of the crushed sample continues onto the analysis conveyor and then the sampling conveyor to be further divided by the secondary sampling mechanism. The divided portion of the sample is stored into the containers at the carousel, the remaining part is dumped outside the processing line house.

The sample containers are equipped by closing lids which are only opened in case of filling by the sample. The rotary carousel can handle up to 16 containers for sample storage so that the distinct final samples can be stored selectively according to different suppliers, freighters or other criteria. The sampler can be also equipped by automatic packing machine with indexing for long-term sample storage.

For the best achievable sample representativeness the place of sample extraction from the truck bed is chosen automatically on random basis. Based on the batch size information the system will determine the number of samples taken from the trucks in order to collect suitable amount of final sample for the laboratory analysis.

The sampler is controlled from the operator cabin. The process of sample extraction and processing is pre-programmed and fully automatic. Work of the operator is limited to start the automatic operation and supervision. Communication with the system is ensured by the rugged industrial-grade control panel where it is possible to monitor, change and setup all working parameters of the automatic system, e.g. the time of sample extraction, number of samples taken, statistics of samples taken for each supplier, status of individual devices etc. It is also possible to set the parameters of the sampling process and view the errors and alarm messages.
