Grate Kiln System
The grate chain travels flat and straight. the grate travels through a furnace with several zones that expose the pellets to different temperatures. once the pellets are discharged into the kiln, the grate chain returns underneath. the grate is driven by a motor with gearbox or hydraulic drive. the grate is supported by rollers. rotary.The rotary kiln provides constant mixing of the pellets, bringing all the pellets to the same temperature. in a straight grate, the pellets at the top of the bed are “over cooked” and those at the bottom are “under cooked”. higher quality means fewer fines, better reducibility and less variation in compression.
