Abstract: The “sludge dehydrator” equipment is a machine that permits to remove low turbidity water from sludge or watery pastes of industrial or mining origin, with the following objectives: To optimize ore recovery processes such as flotation by means of an increase of the sludge density; To thicken sludge or watery pastes for optimizing the filtering and drying processes, as well as to dispose of mining tailings; To concentrate and dispose of solids in suspension and to recover and recycle clean or clarified water.

Abstract: The invention “compass-effect magnetic rotor” refers to an iron bar winding to which a DC current is applied to convert it into an electromagnet, this iron bar being centrally mounted on a shaft in such a way that when the whole assembly is oriented North-South the bar will point North-South because it acts as a simple compass, however; when the iron bar is aligned with the Earth's magnetic north, the polarity of the bar is changed, changing the direction of electricity supply and hence the iron bar will rotate permanently and successively thereby attaining continuous rotation of the iron bar on the shaft perpendicular to the center thereof. The energy generated by the Earth's magnetic field is thus utilized and converted into mechanical energy through the permanent rotation of the “compass-effect magnetic rotor,” which in turn converts said energy into electricity by means of a generator connected to the shaft.
