  • difference between rotary kiln and straight grate technology

    difference between rotary kiln and straight grate technology Comparing both technologies the bed height in the straight grate technology is higher The straight grate technology requires the use of hearth layer which ranges between 6 and 10cm in height whereas the green pellet height is typically between 30 to 45cm In the gratekiln system theThe 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 strengthRotary kilns Outotecprocess: a preheat travelling grate, a rotary kiln, and an annular or straight cooler Drying and preheating of the green pellets is accomplished on the preheat grate, while the pellets are fired in the rotary kiln and finally cooled in the annular or straightCONTRIBUTIONS TO THE TECHNOLOGY COMPARISON
