Most of the organic fertilizer making adopts the wet granulation. This means that pellets will have too much moisture for packing it into bags directly after granulation. Here, we design the rotary drum dryer to quickly reduce the moisture below 13%, a premium level.
Through the high temperature of the dryer, we must cool down the granules. Otherwise, the high temperature will affect the quality of final piggery waste fertilizer pellets. The drum of SX cooling machine is a 10 mm thick one-piece spiral tube with high concentricity and strong rigidity. And the thickness of the lifting plate is 5 mm. So it has a long service life.
