An ice crushing system includes multiple sets of interleaved blades with some of the blades being provided with a series of raised protrusions on one or more faces. With this arrangement, the spacing between the interleaved blades is reduced and a finer crushed ice consistency is established. In accordance with aspects of the invention, the raised protrusions are staggered along each side of a set of fixed blades, with the raised protrusions on one side of a fixed blade overlapping the raised protrusions on the opposing side.

1. A refrigerator comprising: a cabinet having defined therein a refrigerated compartment;an icemaker;a dispenser for water and/or ice; andan ice crushing system interposed between the icemaker and the dispenser, said ice crushing system including a plurality of interleaved, relatively rotatable blades, at least some of said plurality of interleaved blades including raised protrusions reducing spacing with adjacent ones of said plurality of interleaved blades. 2. The refrigerator according to claim 1, wherein the plurality of interleaved blades are constituted by a first set of rotatable blades and a second set of fixed blades which are interleaved with the first set of rotatable blades. 3. The refrigerator according to claim 2, wherein the raised protrusions are provided on the second set of fixed blades. 4. The refrigerator according to claim 3, wherein each of the second set of fixed blades includes opposing face portions, with the raised protrusions projecting from each of the opposing face portions. 5. The refrigerator according to claim 4, wherein the raised protrusions on the opposing face portions of each of the second set of fixed blades are staggered along a length of the each of the second set of fixed blades. 6. The refrigerator according to claim 5, wherein the raised protrusions on one of the opposing face portions overlap the raised protrusions on another one of the opposing face portions. 7. The refrigerator according to claim 1, wherein the ice crushing system further includes a divider plate arranged adjacent one of the plurality of interleaved blades, wherein the divider plate is provided with at least one protrusion extending toward the one of the plurality of interleaved blades. 8. The refrigerator according to claim 1, wherein each of the at least some of said plurality of interleaved blades includes opposing face portions, with the raised protrusions projecting from each of the opposing face portions. 9. The refrigerator according to claim 8, wherein the raised protrusions on the opposing face portions of each of the second set of fixed blades are staggered along a length of the each of the second set of fixed blades. 10. The refrigerator according to claim 9, wherein the raised protrusions on one of the opposing face portions overlap the raised protrusions on another one of the opposing face portions. 11. An ice crushing system comprising: a plurality of interleaved, relatively rotatable blades, at least some of said plurality of interleaved blades including raised protrusions reducing spacing with adjacent ones of said plurality of interleaved blades. 12. The ice crushing system according to claim 11, wherein the plurality of interleaved blades are constituted by a first set of rotatable blades and a second set of fixed blades which are interleaved with the first set of rotatable blades. 13. The ice crushing system according to claim 12, wherein the raised protrusions are provided on the second set of fixed blades. 14. The ice crushing system according to claim 13, wherein each of the second set of fixed blades includes opposing face portions, with the raised protrusions projecting from each of the opposing face portions. 15. The ice crushing system according to claim 14, wherein the raised protrusions on the opposing face portions of each of the second set of fixed blades are staggered along a length of the each of the second set of fixed blades. 16. The ice crushing system according to claim 15, wherein the raised protrusions on one of the opposing face portions overlap the raised protrusions on another one of the opposing face portions. 17. The ice crushing system according to claim 11, further comprising: a divider plate arranged adjacent one of the plurality of interleaved blades, wherein the divider plate is provided with at least one protrusion extending toward the one of the plurality of interleaved blades. 18. A method of producing finely crushed ice comprising: directing ice cubes between a plurality of interleaved, relatively rotatable blades of an ice crushing system wherein at least some of said plurality of interleaved blades include raised protrusions reducing spacing with adjacent ones of said plurality of interleaved blades to produce finely crushed ice. 19. The method of claim 18, further comprising: operating an auger to both direct the ice cubes between the plurality of interleaved blades and rotate a first set of the plurality of interleaved blades relative to a second, fixed set of the plurality of interleaved blades, with the raised protrusions being on the second, fixed set of the plurality of interleaved blades. 20. The method of claim 19, wherein the raised protrusions are provided on opposing sides of each of the second, fixed set of the plurality of interleaved blades for producing the finely crushed ice.
