What are the fertilizer granulating machines in the organic fertilizer production line and what are their characteristics
1. The disc granulator (also known as the ball plate) is a volumetric metering feeding equipment, which can feed the material to the next process uniformly and continuously, and can withstand a large bin pressure. As a fine material feeding equipment, the organic fertilizer granulation machine is suitable for conveying various non cohesive materials in powder, material or small state, such as pulverized coal, cement, clinker, limestone, shale, coal gangue, clay and other powder, granular or small block materials.
The disc angle of the disc granulator adopts the whole arc structure, and the granulation rate can reach more than 93%. The pelletizing plate is equipped with three discharge ports, which is convenient for intermittent production operation, greatly reduces the labor intensity and improves the labor efficiency. The reducer and motor are driven by flexible belt, which can start stably, slow down the impact force and prolong the service life of the equipment. This surface has the advantages of uniform granulation, high granulation rate, stable operation, strong and durable equipment, long service life and so on
2. The rotary drum granulator is a kind of granulating equipment widely used in the production of compound fertilizer, organic fertilizer, biological fertilizer, controlled-release fertilizer and so on. Rotary drum granulator is suitable for cold and hot granulation and large-scale production of high, medium and low concentration compound fertilizer. The main working mode is granulation by wet granulation. Through a certain amount of water or steam, the basic fertilizer can be fully chemically reacted after being humidified in the cylinder. Under certain liquid phase conditions, with the help of the rotary motion of the cylinder, the material particles will produce extrusion pressure and agglomerate into balls.
1. The pelletizing rate is up to 70%, the pelletizing strength is high, there is a small amount of returned material, and the particle size of the returned material is small, so it can be granulated again;
2. Steam is introduced to heat the material to increase the temperature of the material, so that the moisture content of the material after pelletizing is low and the drying efficiency is improved;
3. The cylinder body of rotary drum granulator adopts special rubber plate lining or acid resistant stainless steel lining plate, which is corrosion-resistant and wear-resistant. At the same time, it realizes automatic scar removal and tumor removal, and cancels the traditional scraper device.
3. The double roller granulator is produced by the process of no drying and normal temperature, and is formed in one time. The double roller granulator has the advantages of less investment, quick effect and good economic benefit. The complete set of equipment is compact in layout, scientific and reasonable, and advanced in technology. Energy saving and consumption reduction, no three wastes discharge, stable operation, reliable operation and convenient maintenance. It is suitable for granulation of compound fertilizer, medicine, chemical industry, feed and other raw materials with high granulation rate. It can produce various concentrations and types of compound fertilizers (including organic fertilizer, inorganic fertilizer, biological fertilizer, magnetic fertilizer, etc.). In particular, rare earth, potassium fertilizer, ammonium bicarbonate series compound fertilizer granulation,
Characteristics of double roller granulator
1. No drying process is adopted for the production of twin roll extrusion granulator, granulation at room temperature and one-time molding. It has the characteristics of less investment, quick effect and good economic benefit.
2. This double roller granulator is characterized by simple operation and low energy consumption. The main parts such as the roller body are refined by a new type of metal which has the characteristics of corrosion resistance, wear resistance and impact resistance.
4. Agitator granulator. It is widely used in granulation of organic fertilizer. Due to more granulation rate, stable operation, strong and durable equipment and long service life, it is selected as the ideal product by the majority of users. The shell of fertilizer granulation machine is made of thickened seamless steel pipe, which is durable and never deformed. In addition, the stable base design makes its operation more stable.
The agitated tooth fertilizer granulation machine can produce pellet products with low moisture content, easy drying, high molding rate, good strength and beautiful appearance. It is an ideal granulation equipment for bio organic fertilizer, organic inorganic fertilizer and organic fertilizer inorganic compound fertilizer. The key technical problems that are difficult to be solved by the traditional pelletizing process of disc (drum) have been solved thoroughly, such as fermentation, etc.
