Fertilizer caked you still knocking on a stick?
Fertilizer agglomeration problem, I believe many people will encounter. Especially in the warehouse for a period of time, the fertilizer is most likely to agglomerate, and the longer the time is, the more serious the agglomeration becomes. Fertilizer is not easy to sell, and it seems to farmers' friends that the agglomeration is fake fertilizer. Therefore, many dealers had to arrange workers to beat round sticks, which was time-consuming and laborious. Manufacturers will be returned by dealers because of agglomeration problems. 1. What are the reasons for fertilizer agglomeration? 1, first from the raw material analysis, mainly raw materials are easy to dissolve In general, the main raw materials for compound (mixed) fertilizer production are urea, ammonium chloride, ammonium nitrate, ammonium sulfate, diammonium phosphate, monoammonium phosphate, superphosphate, potassium chloride, and potassium sulfate. Compound (mixed) fertilizers made from these readily soluble fertilizers tend to agglomerate during storage and transportation. 2. Look at other factors that affect fertilizer agglomeration 1) High fertilizer moisture content Fertilizer's moisture content is the biggest factor in agglomeration of fertilizers during storage. The higher the moisture content, the easier the dissolution of salt in the fertilizer particles, the more likely physical and chemical reactions take place. After recrystallization, agglomeration is likely to occur, and repeated dissolution occurs. - Crystallization can lead to severe agglomeration. 2) Uneven particle size and low compressive strength of the product Fertilizer granules are small or the particle size is not uniform, the gap between the granules is small, the specific surface area is large, and the contact area between the granules is large, and it is easy to agglomerate. If the compressive strength of the fertilizer particles is low, the fertilizers are easily deformed and broken during the packaging, transportation, and storage, which increases the contact area between the particles and easily causes agglomeration of the fertilizer. 3) Pressure between fertilizers when stacked When the fertilizer is stored, the particles are in close contact with each other under the action of gravity, and they are easily deformed. The stacking height is high. The greater the pressure on the fertilizer, the greater the number of indirect contact points of the particles, and the easier the agglomeration. 4) Long storage time The longer the storage time of the fertilizer product, the more recrystallized surface of the fertilizer granules - the more frequent the dissolution process, plus the prolonged exposure to a certain pressure, the tendency of agglomeration is obvious. 5) high packaging temperature High packaging temperature, insufficient cooling of the finished product, insufficient internal moisture release, and high temperature, the solubility of the corresponding salt is large. In the storage process, as the temperature decreases, the solubility of the salt decreases. Crystals are precipitated, resulting in crystal bridges that cause agglomeration. 6) There is a large amount of fertilizer powder at the time of packaging During the cooling and packaging of the fertilizer granules, friction occurs between the granules to generate a certain amount of dust. The dust is present between the granules and acts as a “bridgeâ€, which increases the contact area between the fertilizer granules and also results in compaction. Second, how to effectively prevent fertilizer agglomeration? Take a look at the production side: 1. Reducing the moisture content of the fertilizer and the temperature of the packaging, dehumidifying the unit by heating and dehumidifying the dryer and installing air-conditioning, etc., make the fertilizer moisture below 0.6%, prolong the cooling time of the fertilizer, and reduce the packaging temperature. 2. Add anti-caking agent to raw materials to reduce physical and chemical reactions between particles. 3. Through the transformation of the screening system, further improve the uniformity of fertilizer particles. 4. Reduce the height of the palletization of fertilizers and reduce the storage pressure. Look at dealers? 1. Reduce the temperature and humidity of the warehouse, store the fertilizer in a cool and dry place, ensure that the roof is not leaking, the ground is not filled with water, the warehouse is equipped with exhaust fans, and if necessary, cooling and dehumidification are performed. 2. Fertilizers are frequently bagged after storage for a period of time, especially fertilizers with high nutrient content. They are more likely to be agglomerated when they are stored for a long period of time, and they need to be frequently turned over. 3. Fertilizers that are prone to chemical reactions are stacked separately to prevent chemical reactions from agglomeration. 4. Reduce the height of the fertilizer stack and reduce the pressure between the particles. 5. Avoid blind orders, reduce inventory pressure and prevent excessive accumulation of fertilizer for a long time. 6. Select the regular manufacturer's products to prevent poor granulation of the product and agglomeration due to uneven particles. squid Ring Squid Ring ZHEJIANG EVERNEW SEAFOOD CO.,LTD , https://www.evernewseafood.com
