Abstract (en)
[origin: EP3239635A1] A system to detect and counteract a crank in a rotary kiln having a kiln shell (1) and arranged on tyres (2, 2') supported by support rollers (3, 3') comprises a displacement sensor (5) configured and arranged to sense a displacement of the support rollers (3, 3'), a controller (11), and a plurality of nozzles (7) or fans for dispensing a cooling fluid onto the kiln shell (1). The controller (11) is configured to receive data from the displacement sensor (5), to process the received data by applying a sine fit to the data and determine amplitude and phase, to compare the amplitude of the displacement to a threshold value, and to control a valve (13) to release a cooling fluid to the nozzles (7). The system enables detection of a kiln crank and a selective cooling of the kiln shell within a determined angular range (±). A method is also claimed.
