摘要: A method and apparatus for determining the reflectivity of the tailings from a coal flotation cell to optimize the cell operation. A photoelectric detector determines the coal content of the tailings and through a process controller; frother and collector addition to the cell is monitored. An ultrasonic energy vibration is periodically transmitted to the detector to remove deposits on the detector to optimize detector operation.

摘要: An apparatus for determining the reflectivity of the tailings from a coal flotation cell to optimize the cell operation. A bifurcated fiber optic cable has ends connected to a light source and a photoconductor, with a scanner end of the cable being submersed in a coal slurry. Light transmitted to the scanner end of the cable is backscattered to the photoconductor to function as a detector to determine the coal content of the tailings and through a process controller, frother and collector addition to the cell is monitored. An ultrasonic energy vibration is periodically transmitted to the scanner end of the cable to remove deposits thereon to optimize detector operation.

摘要: An optoelectric detector having transparent tubes separated by a thin opaque barrier with LEDs in one tube adjacent one side of the barrier and a photoconductor in the other tube adjacent to the opposite side of the barrier. The LEDs and photoconductor being in close proximity with the photoconductor with the photoconductor only receiving light emitted by the LEDs which is reflected from the solids in medium in which the detector is used.
