摘要： A method and apparatus for washing and separating pieces of plastics material from contaminants includes supplying to a washing container pieces of plastics material containing contaminating material and an entering flow of washing fluid. A turbulent stirring action to detach and separate mechanically the contaminating material from the plastics material is generated. evacuating through overflowing, through an outlet port An outlet flow of washing fluid and a quantity of plastics material that has undergone the turbulent stirring action is evacuated by overflow through an outlet port. A controlled-conveying and retaining arrangement is driven to retain the plastics material in the washing container and to advance in a controlled manner the quantity of plastics material to the outlet port independently of the advancement of the outlet flow of washing fluid. An adjustable bulkhead is arranged in the washing fluid at a depth with respect to the free surface to divert from the outlet port the pieces of plastics material that, once supplied to the container, by advancing more on the surface, tend to reach the outlet zone of the washings container. The bulkhead guides and forces the pieces of plastics to undergo the turbulent stirring action to separate and detach the adhering contaminants therefrom.

摘要： The present invention provides a method and an apparatus for separating a mixture that are capable of separating a mixture containing a plurality types of particles, using a countercurrent classification technique, even when there is little difference in density and particle diameter depending on the types of particles. In the present invention, a mixture containing first particles and second particles is separated using a separation tube 13 having the inverted-conical or pyramidal shape or a substantially inverted-conical or pyramidal shape. The first particles and the second particles are made of substances having different magnetic susceptibilities. A fluid is caused to flow upward through the separation tube 13, and the flow of the fluid is used to introduce the mixture into the separation tube 13. The first particles and the second particles are held in the separation tube 13 in a mixed state. A gradient magnetic field is applied to a region inside the separation tube 13 using magnetic field generation means 23, in the state where the first particles and the second particles are held in the separation tube 13. The magnetic field gradient of the gradient magnetic field has a vertical component.

摘要： A hindered-settling fluid classifier is adapted for processing aggregate entrained in a flowing slurry. The classifier includes a classifier tank defined by walls, and having an inlet at its upstream end and an outlet at its downstream end. A slurry feed pipe is connected to the tank inlet for introducing the aggregate slurry into the classifier tank for processing. A plurality of laterally-extending flow control doors are spaced apart along a length of the classifier tank, and are adapted for interrupting flow of the aggregate slurry downstream from the tank inlet to the tank outlet. The doors define respective material settling zones each located a progressively greater distance downstream from the tank inlet. At least one water line is provided for generating an upwardly rising current in each of the material settling zones to control the settling velocity of aggregate floating downwardly towards a base of the classifier tank. A plurality of collection hoppers are located at the base of the classifier tank and below respective settling zones for collecting and classifying aggregate settling within the zones.
