The AshScan Low Energy Transmission (LET) analyser combines state-of-the-art nuclear technology with ground-breaking modelling and powerful statistical analysis. Installed on a conveyor belt, the AshScan delivers accurate, minute-by-minute data on percentage ash content present in the coal feed to the kiln.
Coal is still the primary fuel used to deliver the energy required in the kiln firing process. The control of the fuel quality is an challenge for operations were reliance is placed on the data from suppliers to optimize the kiln firing process. The AshScan can provide critical ash and moisture analysis in real time to enable operators to make pro-active decisions on control parameters such as secondary fuel addition, burning zone temperature, drying and calcining, kiln speed and fuel rate to name but a few. The real time data on primary fuel quality enable operators to vary the kiln speed, fuel rate and the induced fan speed in any combination to maintain a proper burning zone temperature and constant kiln back-end temperature for any given input feed rate. AshScan provide specific benefits such as: Protection of equipment and personnel, stable kiln operation, maximum production rate coupled with maximum fuel efficiency and production of a consistent quality clinker.
The AshScan utilises two radioactive sources. The technology is referred to as Dual Energy Transmission (DET) or Low Energy Transmission (LET).
The AshScan has proprietary counting electronics, which is the fastest available on the market. The measurement and output has the fastest update time of less than 25 seconds.
The AshScan provides real time analysis of ash content in coal that is used to improve monitoring, sorting and blending operations in:
AshScan is used for the applications of Raw Coal in mining, Plant Feed control, Stockpile building and Blending of coal to meet stringent quality requirements.
The AshScan is the most affordable, accurate and easy-to-install cross belt analyser analyser of its kind in the world today.
Combining state-of-the-art nuclear technology (LET) the AshScan delivers accurate, minute by minute ash content analysis and reporting of Key Process Parameters such as:
