Multiple-choice question: What are the main factors affecting the granulation conditions in the conventional drum granulation process? ( ) 1. Rotary drum speed; 2. Particle size, temperature, and moisture content of raw materials; 3. Urine concentration and amount of steam added; 4. Angle of the spray nozzle; 5. Particle size, flow rate, and temperature of the recycled material; 6. Material of the reactor. In the compound fertilizer and functional fertilizer sections, a “One Question per Day” activity on basic production knowledge is conducted. We hope that all Sea Friends will actively participate. The purpose of this activity is to revisit the knowledge we’ve already learned; through answering questions, it aims to improve and strengthen each participant’s foundational theoretical knowledge—reinforcing what they already know and helping them recall what they may have forgotten. There will be rewards for the top 50 answerers. Please reply with the answer hidden; otherwise, it will be invalid. Hidden. See method here: http://bbs.hcbbs.com/thread-492556-1-1.html. Please do not edit after replying! 1, 2, 3, 4, 5
