Abstract
A machine for the heating of granular material at high temperature, wherein a vessel is divided into compartments by vessel dams and vibrated in a direction perpendicular or ‘Cross Axis’ to the vessel longitudinal axis. The vessel is vibrated by counter rotating rotary vibrators to create a “Cross Axis” vibration causing a circular cascading movement of the granular material within the vessel. The vessel is surrounded by a furnace heated by electric power or a combustible gas.
Claims7
A calciner for heating a granular material, the calciner comprising:
- a. an elongated vessel having a feed chute proximate a front plate, a discharge chute proximate an end plate, and a longitudinal axis extending from the front plate to the end plate;
- b. a plurality of vessel dams substantially equally spaced along the longitudinal axis, each of the plurality of vessel dams having an upper portion and a lower portion, each of the upper portion and the lower portion oriented substantially orthogonal to the longitudinal axis, the upper portion having an upwardly inclined edge, the vessel dams shaped and located such that passage of the granular material from the feed chute to the discharge chute along the longitudinal axis is blocked by the lower portion of the vessel dams and the granular material must traverse each of the vessel dams by passing above the upwardly inclined edge of the upper portion;
- c. a platform on which the vessel is mounted;
- d. two rotary vibrators attached to the platform and spaced apart along the longitudinal axis, wherein one of the rotary vibrators is configured to have a direction of rotation counter to a direction of rotation of the other of the rotary vibrators, the direction of rotation of each of the rotary vibrators being perpendicular to the longitudinal axis of the vessel;
- and
- e. a furnace which surrounds the vessel.
A method for moving a granular material through a vessel, the method comprising:
- a. providing:
- i. an elongated vessel having a feed chute proximate a front plate, a discharge chute proximate an end plate, and a longitudinal axis extending from the front plate to the end plate;
- ii. a plurality of vessel dams substantially equally spaced along the longitudinal axis, each of the plurality of vessel dams having an upper portion and a lower portion, each of the upper portion and the lower portion oriented substantially orthogonal to the longitudinal axis, the upper portion having an upwardly inclined edge, the vessel dams shaped and located such that passage of the granular material from the feed chute to the discharge chute along the longitudinal axis is blocked by the lower portion of the vessel dams and the granular material must traverse each of the vessel dams by passing above the upwardly inclined edge of the upper portion;
- iii. a platform on which the vessel is mounted;
- and
- iv. two rotary vibrators attached to the platform and spaced apart along the longitudinal axis;
- b. adding granular material to the vessel through the feed chute;
- c. vibrating the vessel by rotating the two rotary vibrators such that one of the rotary vibrators has a direction of rotation counter to a direction of rotation of the other of the rotary vibrators, and the direction of rotation of each of the rotary vibrators is perpendicular to the longitudinal axis of the vessel, thereby causing the granular material to pass through the vessel along the longitudinal axis and traverse the vessel dams;
- and
- d. discharging the granular material through the discharge chute.
