Process characteristics of roll extruding granulator for organic fertilizer

  1. Low energy consumption oforganic fertilizer roller granulator: extrusion granulation is the granulation of materials at room temperature. Compared with other granulation methods, it does not require drying measures such as fuel oil and gas. The production only requires power consumption and a small amount of cooling water (for roller shaft cooling), and the power consumption per ton of product is only about 30 kW/h.
  2. There is no need to add adhesive to the organic fertilizer roller granulator: other granulation processes are basically wet processes, which must have a drying process, with high energy consumption and high product moisture. However, dry granulation does not require additional additives, but only uses the intermolecular force of the material itself, simplifying the process and reducing energy consumption.
  3. The investment of theorganic fertilizer roller granulatoris low: because the drying process is omitted, and the return ratio is low (accounting for about 35% of the total feed of the extruder), the process flow is simple and the investment is low.
  4. Wide range of applicable raw material particle specifications: extrusion granulation has no special requirements on the particle size of raw materials. Both 1~4mm granular materials and fine
