redirecting a portion of a flowing stream of material the deflector includes an attachment means to attach the deflector to the spiral separator a capturing portion to capture a portion of the flowing stream and a redirecting portion to emit a portion of the stream a method of separating particles of different densities using the deflector device in conjunction with a spiral separator is also disclosed application_number US 40155306 A description throughout the drawings like numerals will be used to identify similar features except where expressly otherwise indicated as shown in the drawings the deflector generally designated by the numeral i is adapted to be attached to a spiral separator generally designated by the numeral 2 the deflector 1 is designed to capture and redirect a controlled portion of the flowing stream of material flowing through the spiral separator the deflector 1 generally includes an attachment means 3 for attachment of the deflector 1 to the spiral separator 2 a capturing portion 4 shaped to substantially ride atop and capture a portion of the flowing stream of material 5 and a redirecting portion 6 which is integrally formed with the capturing portion 4 and which is shaped to spray or otherwise emit the captured material as illustrated by reference numeral 7 the spray 7 may be patterned to be of any desired shape depending upon the desired pattern of the spray as it re enters the main stream for example the spray may be fan shaped substantially hemispherical in shape or any other thin broad canopy of spray such that it re enters the main stream substantially in.
