Rollers has a very large workload and needs to be rotated continuously. The rotation will generate high temperatures, and excessively high temperatures will damage the machine and affect production. The manufacturer also noticed this problem and used a butter pump to continuously add butter to ensure lubrication. The grease in butter is a complex, and the grease inside is consumed at high temperatures. We usually recommend that if the pellet factory operates the machine all day long, it needs to clean the roller bearings every 5-7 days to remove the filler that cannot provide lubrication. In short, if you are a novice and do not know how to maintain the machine, you should still follow the factory's recommendations to maximize your own benefits.
