Rotary Drum Granulator (also known as balling drums, rotary pelletizer or rotary granulators) is quite popular equipment that can process a wide array of raw materials. The equipment is typically used for large-scale production of compound fertilizer with cold, hot, high concentration and low concentration. The machine has the advantages of high ball forming strength, good appearance quality, corrosion resistance, low energy consumption and long service life. Small power, no three wastes discharge, stable operation, convenient maintenance, reasonable process layout, advanced technology, low production costs. Rotary Drum Compound Fertilizer Granulators are used when an agglomeration – chemical reaction process is required.
