Grate Kiln For Sale – Grate Kiln System | AGICO Grate Kiln ...

Pellets produced by grate kiln system have fewer fine particles, better reducibility, and less compressive strength change. They are continuously mixed in the rotary kiln so that all of them can reach the same temperature. While in the straight grate, pellets at the top of the material layer frequently occur over-indurating phenomenon.
