Feb 01, 2011· Themillhas severalliftersone of them (marked 1) is equipped with a leaf spring whose deflection is measured by the strain gauge (marked 2). As themillrotates and thelifterwith the sensor dips into the charge, the force acting on thelifterincreases, which in turn, causes a deflection.
The modelling approach has been applied on atumbling millwhere a strain gauge sensor measures the deflection of alifter barwhen it hits the charge. The deflection of thelifter barduring everymillrevolution gives rise to a characteristic signal profile that is shown to contain information on both the charge position and grinding performance.
