Granulation technology of double roller organic fertilizer granulation machine
The double roller organic fertilizer granulation machine uses pressure to agglomerate the solid materials, and then extrudes the materials by two reverse rotating roller shafts, which are driven by eccentric sleeve or hydraulic system. When the solid material is extruded, the air between the powder particles is removed first, so that the particles are rearranged to eliminate the gap between the materials.
The thickness of the large piece of organic fertilizer granulation machine is 5-20 mm, and the surface density is 1.5-3 times of the feed material. The required granular products are obtained after the large pieces are flaked, crushed and screened. The particles formed by pressure form a hot spot at the contact point and melt the material. When the temperature drops, the material cools to form a fixed bridge.
The double roller granulator is used for granulation of various organic matters after fermentation, breaking through the conventional granulation process of organic matters. Before granulation, the raw materials need not be dried and crushed, and the spherical particles can be processed directly, which can save a lot of energy.
