Dried Compost Pellets Production

For dry granulation of organic compost, double roller press machine is the best choice. It mainly makes use of double roller opposite moving to make compressed compost fertilizer pellets. In terms of design, the machine has advantages of over 97% granulating rate, 20CrMnTi or 4Cr13 stainless steel roller material and screen adding. Moreover, the roller compactor also suitable for making organic fertilizer granules from compost in small and large scale. Single equipment output is 1-3 t/h. But with more roller granulators, you even can setup a 10 t/h compost fertilizer granulation plant.

When you need a dry granulation equipment for your granulated compost making, we recommend you flat die pellet mill. The machine not only can meet you requirements of 1-2.5 t/h compost granulation, but also has a lower price and less area occupation. But, the final compost particle shape is column. Because it uses a flat die and a rotary roller to compress compost powder into organic granules. The roller press organic material into die holes, then cut into short fertilizer pellets by blades.

Then, the ring die pelletizer is the upgrading version of flat die pellet mill. Similarly, it make column compost fertilizer pellets with 1-10 mm size for you. However, it has a large output of compost granules production. In the process of organic fertilizer granulation, the working principle is also similar with flat die granulation. It feeding organic compost into ring-shaped die. Then the centered roller will press material into the ring die. Finally, the finished compost rods will be cut by rotary scrapers.
