Abstract (en)
[origin: EP1108816A2] The method involves using a mobile sand cleaning device with a frame carrying an adjustable sand elevator (60) with a continuous circulating conveyor with conveying elements. The raising and lowering of the elevator is detected by a sensor (S1) whose signals pass to a signal processor (100) that derives data for internal processing and the computation of the quantity of sand cleaned over a defined period..
