1. A system for cooling aggregate, the system comprising: a drum comprising:an aggregate inlet;a plurality of buckets, in which holes are designed, arranged in a ring around a circumference of the drum, and a plurality of rings arranged along a length of the drum, wherein each of the plurality of buckets has openings that open into an interior of the drum;one or more radial donuts or radial webs within the interior of the drum;an aggregate outlet;a cooling air supply; andan external body that entirely encapsulates the plurality of buckets,wherein one or more buckets define respective second openings that expose an aggregation disposed in the one or more buckets,wherein the external body comprises a plurality of openings that are in direct communication with external atmospheric conditions, andwherein the second openings are in direct communication with the plurality of openings of the external body to provide direct external cooling of the aggregation through external walls of the buckets. 2. The system of claim 1, wherein the plurality of buckets is twelve buckets. 3. The system of claim 1, wherein the buckets have a depth of approximately 1 m. 4. The system of claim 1, wherein the buckets have an opening angle of approximately 45 degrees, and start at an end of a radial donut. 5. The system of claim 1, wherein the predetermined width is approximately 0.6 m. 6. The system of claim 1, wherein the cooling air supply is counter current to the direction of travel of the aggregate through the drum. 7. The system of claim 1, wherein the drum is rotated to move the aggregate along a length of the bucket which contains holes, between the plurality of buckets and along the length of the drum. 8. A method for cooling aggregate, the method comprising: supplying hot aggregate to an end of a drum, wherein the drum comprises an aggregate inlet; a plurality of buckets in which holes are designed, arranged in rings around a circumference of the drum, and a plurality of rings arranged along a length of the drum, wherein the plurality of buckets has openings that open into an interior of the drum; one or more radial donuts or radial webs within the interior of the drum; and an aggregate outlet;rotating the drum to cause movement of the aggregate along a length of the bucket which contains holes, between the plurality of buckets and along the length of the drum; andsupplying cooling air to the interior of the drum,wherein the drum further comprises an external body that entire encapsulates the plurality of buckets,wherein one or more buckets define respective second openings that expose an aggregation disposed in the one or more buckets,wherein the external body comprises a plurality of openings that are in direct communication with external atmospheric conditions, andwherein the second openings are in direct communication with the plurality of openings of the external body to provide direct external cooling of the aggregation through external walls of the buckets. 9. The method of claim 8, wherein the radial donuts move the aggregate along the length of the drum. 10. The method of claim 8, wherein the cooling air is supplied in a counter current to the movement of the aggregate along the length of the drum. 11. The method of claim 8, further comprising removing cooled aggregate from the aggregate outlet. 12. The method of claim 8, wherein the plurality of buckets is twelve buckets. 13. The method of claim 8, wherein the buckets have a depth of approximately 1 m. 14. The method of claim 8, wherein the buckets have an opening angle of approximately 45 degrees, and start at an end of a radial donut. 15. The method of claim 8, wherein the predetermined width is approximately 0.6 m.
