The biggest highlight of rotary drum granulator is its strong adaptability to raw materials. It covers almost all powdery and finely divided fertilizer raw materials. It does not require complicated modification processing and is suitable for the production of organic fertilizers, compound fertilizers, biological fertilizers and other categories. It can be divided into three major categories: 1. Organic raw materials Decomposed livestock and poultry manure (chicken manure, sheep manure, cow manure, pig manure), crushed straw, sawdust, fungus residue, sugar residue, sludge, kitchen fermentation materials, cakes and other agricultural and industrial organic waste are the core processing equipment of the organic fertilizer production line. 2. Compound fertilizer raw materials Basic chemical fertilizer powders such as urea, monoammonium phosphate, diammonium phosphate, potassium chloride, potassium sulfate, calcium magnesium phosphate fertilizer, bentonite, kaolin, etc. can process high, ...

  After daily shutdowns, promptly clean residual raw materials from the roller shells and feed hopper to prevent material caking and corrosion of the roller surfaces; do not use hard objects for scraping, as this can cause wear or tooth damage to the roller shells. Check the gap between the roller shells during every shift to ensure uniformity; make fine adjustments if the deviation is excessive to prevent uneven granule size. Regularly replenish grease in the gearbox and bearing housings—adding grease every three days and performing a complete oil change monthly—to prevent dry friction caused by a lack of lubrication. Clean dust from drive chains and belts, maintain proper tension (tightening them promptly if loose), and immediately replace any damaged parts. Before startup, check the tightness of all bolts—paying special attention to the roller pressing assembly and the machine frame's anchor bolts—to prevent loosening due to operational vibration. Strictly prohibit hard metal ob...
