Abstract
An air separator method and apparatus provides a second, preferably downward air stream about and rotating in the same sense as a first, upward air stream to carry away coarser feedstock material siezed from a supply and centrifugally separated from finer feedstock material by the first air stream.
Claims21
Method for the operation of an air separator, prefereably a circulating air separator, which is equipped with a separating chamber terminating at its bottom in a coarse material collector provided with a discharge spout into which collector the feedstock is delivered in dispersed form and is seized by an upward stream flowing through the separating chamber rotatingly from bottom to top, the coarse material being moved towards the separating chamber casing periphery and the fines being removed from the separating chamber by a removal air stream, characterized in that to the upward air stream a flow rotating in the same sense is delivered adjacent the casing periphery (7) and seizes and carries away the coarse material.
In a method of operating an air separator having feedstock material therein, and a first, rotating, upward, feedstock material-seizing air stream for centrifugally separating outwardiy of the rotation of the first air stream coarser components of the feedstock material and carrying away upwardly finer components of the feedstock material, the improvement comprising:
- providing a second air stream about the first air stream and rotating in the same sense as the first air stream at least for carrying away the centrifugally-separated coarser components of the feedstock material.
In an air separator having a separating chamber and feedstock means for supplying feedstock material to the separating chamber, the improvement comprising, in combination:
- first means for providing a first, rotating, upward air stream in the separating chamber for seizing the feedstock material supplied by the feedstock means, rotating the same for centrifugally separating outwardly of the rotation of the first air stream coarser components of the feedstock material, and carrying away upwardly finer components of the feedstock material;
- and
- second means providing a second air stream about the first air stream and rotating in the same sense as the first air stream at least for carrying away the centrifugally-separated coarser components of the feedstock material.
