  • Traveling grates Metso

    The traveling grate is comprised of chain that carries the pellets like a conveyor. The difference is that the grate chain allows air to pass through it. The grate chain travels flat and strait. There are several compartments the pellets are exposed to different heat. Once the pellets are discharged into the kiln the grate chain returns underneath.
