Illustration of the pellet production flow. The cooler is the last and most critical part, subsequent failure lead to stops of the entire production. 
 The cooler weights up to 500 tons and rotates slowly, about two rounds per hour. The extreme conditions demanded a tailor made construction with high focus on robustness.
 Custom shaft mounts enables varying angels of the wheels to fit the various coolers with different radius. 
 The idea of using wear surfaces came up during interviews with mechanics at the plant. Severe wear of the wheels was found to be a problem, causing loss of contact between wheels and cooler.
