Different advantages and characteristics of extrusion granulator

　　There are actually three types of extrusion granulators, namely, roller extrusion granulator, twin screw extrusion granulator and flat die granulator. All types of extrusion granulators belong to dry powder granulation. These different types of extrusion granulators have different advantages and characteristics according to different structures and process principles.

　　Process characteristics and advantages of twin screw extrusion granulator

　　Twin screw extrusion granulator is widely used for direct granulation of organic materials such as poultry manure, urban sludge, domestic garbage, sugar factory filter mud, papermaking sludge, wine lees, bean dregs, straw, peat, etc. to produce pure organic, organic-inorganic and bio-organic fertilizers. .Equipment features The machine has novel design, unique structure, wide applicability of raw materials, large production capacity, high operating reliability, low production cost, high balling rate, uniform, smooth, round and high strength particles.

　　Working principle of double-screw extrusion granulator This machine adopts the new technology of bidirectional spiral countercurrent collision granulation, so that the organic material can obtain continuous, high-speed, reciprocating kneading and shearing in the granulation area, thus forming a high-pressure mechanical flow collision flow. The material temperature rises to more than 60 degrees within 20 seconds, rapidly changing the molecular structure and granulation properties of the material, so that the heat transfer, fluidization and extrusion process between the materials can be significantly enhanced, the granulation density and ball formation rate are significantly improved, the energy consumption and template costs are greatly reduced, and the granulation efficiency is more than 50% higher than that of the traditional extrusion granulator. The motor power is 40% lower than that of the traditional extrusion granulator.

　　Process characteristics and advantages of the double-roll extrusion granulator of the extrusion granulator

　　The double-roll extrusion granulator is a new generation of granulation equipment developed by our company. It adopts the non-drying normal temperature process for production, one-time molding, and an output of 1-5 tons/hour. The equipment has low investment, quick results and good economic benefits. The complete set of equipment has a compact layout, scientific and reasonable, and advanced technology. Energy saving and consumption reduction, no discharge of three wastes, stable operation, reliable operation, and convenient maintenance. The raw materials have wide adaptability and are suitable for granulation of various raw materials such as compound fertilizers, medicines, chemicals, feeds, etc., with a high granulation rate. It can produce compound fertilizers of various concentrations and types (including organic fertilizers, inorganic fertilizers, biological fertilizers, magnetic fertilizers, etc.). Especially the granulation of rare earth, potash fertilizer, and carbon ammonium series compound fertilizers is a promotion project of environmental protection projects!

　　Structural features of the double-roll extrusion granulator:

　　The structure integrates granulation, molding, and screening, making it beautiful in appearance, simple to operate, and low in energy consumption. The main parts such as the roller body are made of new metals with corrosion resistance, wear resistance, and impact resistance. Our company has also upgraded the frame part. The bearing frame uses excellent anti-corrosion casting as an integral part, which makes it have better stability and can greatly improve the service life of rolling bearings and large shafts. The transmission part adopts a dual input transmission method, which not only improves the input power ratio, but also ensures the lubrication and sealing performance of the transmission gear. It has the characteristics of compact structure, good stability, good sealing, low noise, easy operation and maintenance!

　　Technological characteristics and advantages of flat die granulator of extrusion granulator

　　Multifunctional flat die granulator can produce pellet feed, organic fertilizer, cylindrical particles, and can also be connected to polishing equipment to roll cylindrical particles into balls at one time, without returning particles, high balling rate, good strength, beautiful appearance, and is an ideal equipment for organic fertilizer production and feed production particles today. Flat film granulator is used to granulate various organic matter after fermentation, breaking through the conventional organic matter granulation process. Before granulation, there is no need to dry and crush the raw materials. The cylindrical particles can be processed directly by mixing the ingredients, which can save a lot of energy.

　　Features of flat die granulator:

　　The mold has a long service life and low production cost; the pressure wheel is evenly distributed, the operation is stable, and the production efficiency is improved. The screw center pressure adjustment structure is adopted, and the mold gap can be large or small, which is suitable for different materials to ensure the pressing effect. This machine is equipped with Φ1.5-Φ20mm various aperture dies to adapt to different materials granulation and achieve better benefits.

　　From the above, it is not difficult to see that the three different types of extrusion granulators are simple to form, low investment, quick results, and better environmental protection; the double-screw extrusion granulator has more energy-saving advantages; and the flat die granulator has good moisture adaptability.
