Single fertilizers include nitrogen fertilizer, potassium fertilizer, and phosphorus fertilizer. In fertilizers, fertilizers containing two or more components of N, P, K, and other elements are called compound fertilizers, abbreviated as compound fertilizers. A binary compound fertilizer contains two main nutrients, a ternary compound fertilizer contains three main nutrients, and a multiple compound fertilizer contains three or more nutrients.
The advantages of compound fertilizers include high active ingredients and a variety of nutrients; Less side components and minimal adverse effects on soil; Low production cost; Good physical properties. In modern agriculture, different types of compound fertilizers have been produced for graduate students based on the characteristics of different crops. Whether it is fruits and vegetables, grain crops, or trees, compound fertilizers have become one of the unavailable fertilizers.
Compound fertilizer granulator is a molding machine that can manufacture materials into specific shapes. Compound fertilizer granulator is one of the key equipment in the compound fertilizer industry, suitable for cold and hot granulation, as well as large-scale production of high, medium and low concentration compound fertilizers. The main working method is wet granulation of pellets. By using a certain amount of water or steam, the basic fertilizer is humidified in the cylinder and undergoes a thorough chemical reaction. Under certain liquid phase conditions, with the help of the rotational motion of the cylinder, the material particles are squeezed and agglomerated into balls. The cylinder of this machine is lined with special rubber plates or acid resistant stainless steel plates, achieving automatic scar removal and tumor removal, eliminating the traditional scraper device. This machine has the characteristics of high ball forming strength, good appearance quality, corrosion resistance, wear resistance, low energy consumption, long service life, and convenient operation and maintenance.
The use and maintenance of common compound fertilizer granulators in organic fertilizer granulator equipment:
1. Pay attention to the normal operation of various parts of the machine, check the wear level of easily worn parts, and always pay attention to replacing worn parts.
2. The bottom frame plane of the movable device should be cleaned of dust and other objects to prevent the movable bearing from moving on the bottom frame when the machine encounters materials that cannot be broken, resulting in serious accidents.
3. If the bearing oil temperature rises, it should be stopped immediately to check the cause and eliminate it.
4. If there is any impact sound during the operation of the rotating gear, it should be immediately stopped for inspection and eliminated.
