Fully automatic, quick measurement of ash content in coal at storage yard and dumping ground, in tanks and wagons.


Quick quality assessment of:

– run-of-mine,

– preparation products,

– screening products,

– coal blends,

– unknown coals before preparation,

– feed to coal preparation plants and power stations.


– high accuracy of measuring,

– simple calibration and operation,

– cost, time and energy saving,

– operation with computer: data base, reports.


Principle of operation: Measurement of natural gamma radioactivity of coal.

Battery life between charging: Depends on working temperature; accumulator.

12 V/1,8 Ah; Min. 5 hours’ continuous operation at ~20 oC.

Working temperature: -20 oC to 50 oC.

Number of stored calibration: 16 different calibrations can be straight forward and undertaken by a customer.

Number of measurements per pile: 99.

Measurement time: 5 – 999 s (to be chosen).

Readings of Ash %: Instant.

Accuracy: Depends on type of coal: mean ó = 1 % ash.

Data Computerization: The data can be loaded down to a computer for later analysis; RS 232 (9600,n,8,1).
