Strain Gauges To Measure Cracking In Ball Mills

Measuring crack width and spacing in reinforced concrete Strain in the main reinforcement is measured using embedded electric strain gauges It is found that Eurocode underestimates the crack width and crack spacing Measured values of crack (chemically bound) water w n (Mills 1966, Pantazopoulo Mills 1995) It is reasonable to assume that the evaporable water is a function of.

Ovality Sensor Industrial Kiln & Dryer Group

The Ovality Sensor is a measurement tool for rotary kilns, which measures the changes of the roundness curvature in the kiln shell during operation. This elastic deformation is called Ovality and is primarily present in the area of a kiln tire. The measurement gives accurate information about the degree of mechanical loads in the refractory kiln shell and allows defining the.

Assessment Of Mill Lifter Bar Deflection Measurements

Assessment Of Mill Lifter Bar Deflection Measurements

Mar 14, 2008 The modelling approach has been applied on a tumbling mill where a strain gauge sensor measures the deflection of a lifter bar when it hits the charge. The deflection of the lifter bar during every mill revolution gives rise to a characteristic signal profile that is shown to contain information on both the charge position and grinding performance.
