    Abstract: Determining the consistency of a mixture during a mixing process based on feedback from the mixer. The feedback may be indicative of the torque exerted on a motor shaft of the mixer. The consistency of the mixture may be determined based on the amount of torque, rate of change of torque, change in the rate of change of torque and/or a comparison of the torque information to a stored torque profile. The torque may be determined based on the current in the coils of a motor of the mixer (e.g., by measuring the voltage across a precision resistor in series with the coils). Alternatively, the feedback may be indicative of the angular velocity of the motor shaft, sound output by the mixer, vibration of the mixer, color of the mixture, or opacity of the mixture.

    Abstract: A system and method for tailings disposal is disclosed. A coarse tailings feed stream and a coarse tailings crusher for crushing the coarse tailings feed stream is provided. A crushed coarse tailings stream may be produced by the coarse tailings crusher, and a disposal stream comprising the crushed coarse tailings stream may be discarded as geotechnically stable waste product. The system and method may further provide a fine tailings stream and a thickener configured to thicken/dewater the fine tailings stream and produce a thickener underflow fine tailings stream. The system and method may provide a mixer configured to mix the thickener underflow fine tailings stream and the crushed coarse tailings stream to form a combined tailings disposal stream. Dewatering apparatus may also be provided.

    Abstract: A mixer nozzle assembly for mixing fluid introduced into a tank having a tank volume therein. The mixer nozzle assembly includes a stationary body and a rotatable body mounted on the stationary body for rotation about an axis in a predetermined direction. The fluid flows through the stationary body to the rotatable body and exits into the tank volume via one or more outlet apertures, thereby causing the rotatable body to rotate in the predetermined direction about the axis. The mixer nozzle assembly also includes a governor subassembly for controlling a speed of rotation of the rotatable body in the predetermined direction about the axis and a hydraulic circuit for governing a flow rate of hydraulic fluid directed to the governor subassembly, to adjust the flow rate of the hydraulic fluid for adjusting the speed of rotation of the rotatable body to the preselected speed.

    Abstract: The present invention relates to an aerator apparatus. It comprises an aerator with at least one blade driven around a central axis, and a motor coupled to the at least one blade such that the operation of the motor in a first or a second direction results in the operation of the blade in a corresponding first or second direction. The aerator apparatus further comprises a control device comprising a monitoring mechanism to monitor the current drawn by the motor; and a control mechanism to control the direction of the motor. The monitoring mechanism detects a certain value of the current drawn by the motor and the control mechanism is adapted to direct the motor and coupled at least one blade operating in the first direction to do at least one of (i) stop and/or (ii) operate in the second direction. In preferred embodiments, the monitoring mechanism monitors the current drawn by the motor in relation to one or more of the voltage and frequency applied to the motor. An advantage of certain embodiments of the present invention is that they provide an economical unblocking solution for wastewater aerators where the control device detects a change in the current drawn by the motor, and instructs the motor to direct the aerator into a clean cycle to try to dislodge debris built up during normal flow, when the aerator is running clean.
