Measurement & Control SystemsSmartFill (Coal)
360° impact sound analysis of ball mills
A homogenous degree of fineness is vital to ensure optimum combustion properties for your coal. SmartFill – a fail safe, high precision fill level and temperature measurement system for ball mills – has bee developed to help you achieve this.
For the first time ever you can now accurately measure the most important grinding parameter: fill level. Since it is not possible to measure this key parameter directly, measurements need to be taken on the basis of acoustics or vibrations. Previous measuring methods such as microphones have a number of obvious disadvantages that mean they are wholly unsuitable for achieving the exacting standards required by today’s industrial producers even measuring the drive current does not give accurate enough results.
How does SmartFill improve your energy efficiency?
Accurate measurements allow you to control the mill meaning you can maintain an optimum fill-level at all times. Consequently the mill’s operation is stable and regular resulting in a much more uniform coal output.
What is more, setting the optimum fill-level reduces wear to the balls and mill shell. You can avoid overfilling the mill thereby improving the plant’s uptime; this in turn leads to increased levels of production. Irrespective of the type of control system used SmartFill allows you to make the right decisions at the right time. Thanks to SmartFill, you can now act rather than react when controlling your mill.
What type of mills is SmartFill suitable for?
SmartFill (Coal) is suitable for use in a variety of different types of ball mills including (air-swept) tube mills, centre discharge mills and SAG mills. It can also be used irrespective of the type of lining (steel/rubber), grinding media (balls/cylpebs) or grinding process (wet/dry).
SmartFillTM has been on the market for over seven years and is already used by more than 400 companies worldwide in the coal, cement and minerals industry.
