Abstract
A classifier for separating particles is provided. The classifier includes a rotor having a direction of rotation defined by a rotational axis of the rotor, and a plurality of blades disposed on the rotor around the rotational axis. At least one blade of the plurality has a swept orientation in the direction of rotation. The at least one blade is arranged to contact and direct the particles away from the classifier and thereby restrict the particles from concentrating in areas adjacent to the classifier.
Claims20
A classifier for separating particles comprising:
- a rotor having a direction of rotation defined by a rotational axis of the rotor;
- a plurality of blades disposed on the rotor around the rotational axis;
- and
- wherein at least one blade of the plurality has a swept orientation in the direction of rotation, the at least one blade arranged to contact and direct the particles away from the classifier and thereby restrict the particles from concentrating in areas adjacent to the classifier.
A method for separating particles comprising:
- forcing the particles against an upstream side of a classifier that includes a rotor and a plurality of blades disposed on the rotor around a rotational axis of the rotor that defines a direction of rotation of the rotor;
- rotating the rotor in the direction of rotation such that a first stream of the particles flows between the plurality of blades from the upstream side to a downstream side of the classifier, and such that a second stream of the particles is restricted from flowing between the plurality of blades from the upstream side to the downstream side;
- and
- restricting the particles from concentrating in areas adjacent to the classifier via contacting the particles with at least one blade of the plurality that has a swept orientation in the direction of rotation that directs the particles away from the classifier.
A pulverizer mill comprising:
- a classifier that includes a rotor having a direction of rotation defined by a rotational axis of the rotor, the classifier further includes a plurality of blades disposed on the rotor around the rotational axis;
- and
- wherein at least one blade of the plurality has a swept orientation in the direction of rotation, the at least one blade arranged to contact and direct the particles away from the classifier and thereby restrict the particles from concentrating in areas adjacent to the classifier.
