Rotary Drum Granulator (Compound Fertilizer Production Line )As the one of the key equipments in fertilizer industry, rotary drum granulator is applicable to cold, heat, and guniting and ammoniated granulation and big scale fertilizer production of high, medium and low concentration. The cylinder body adopts special stainless steel or rubber plate lining structure. It can remove scars and peel burls automatically. It has the advantages of high intensity of granule, high production, erosion proof, abrasion proof, low energy consumption, long service life, convenient operation an d maintenance, etc. Remark: the yield, granulating rate and the diameter of granular will be effected by different formulation, process procedure and raw materials.
