Powder heater for high-tower compound fertilizer
Thread Content
1. Our company mainly produces nitro compound fertilizers. I would like to ask whether adding 80 kg/T of sulfuric acid an or even more to nitrosulfur-based high-phosphorus products or nitrosulfur-based high-nitrogen formulations will cause the products to clump or become powdery 2. What would be the outcome if the moisture in monoammonium phosphate were pre-treated by using a powder heater to remove the internal moisture, thereby reducing the moisture content in the final product, and then the aforementioned amount of sulfuric acid An was added? 3. Do you have any understanding of the equipment using drum heaters for moisture removal in the Luzhi raw material processing section, and what impact does it have on product caking?
KQ-118 Nitro Series Anti-caking Agent – Cream Anti-caking Agent. I. Properties: This product is composed of a mixture of anionic and cationic surfactants as well as polymer compounds. The substances characterized by \"high three properties\" and \"two types of aversion\" it contains rapidly form a hydrophobic coating layer on the surface of the particles, changing the surface of the fertilizer particles from hydrophilic to hydrophobic. This prevents environmental moisture from spreading across the surface of the fertilizer particles, reduces capillary adhesion between the particles, and hinders the formation of crystal nuclei or alters the properties of the crystals, thereby achieving the goal of preventing caking. II. Technical Requirements Item Specifications KQ-118B KQ-118 Appearance: Light yellow or yellow-brown paste (when solidified) Density (at 70°C, g/cm3): ≤0.95 Acid value (mgKOH/g): ≥80, ≥10 Melting point (°C): ≥45 III. Features 1. Environmentally friendly, non-toxic and harmless. 2. Scientifically formulated, it exhibits superior performance in terms of spreading, film formation, hydrophobicity, and crystal suppression. 3. Surfactants with “two highs and three increases” exhibit a strong interaction with nitro groups. IV. Applications: It is mainly used to prevent caking in nitro-high-nitrogen compound (mixed) fertilizers. V. Dosage: It should be added by direct heating, stirring, and spraying; the recommended dosage is 1.5–2.5 kg/t. The dosage can be reduced as appropriate when it is used in combination with powdered fertilizer anti-caking agents ； The amount to add can also be determined based on the actual clumping situation. VI. Usage Method 1. Operating Procedure (1) Heat this product until it melts, then stir it before use. The appropriate process conditions are a temperature of 70~90°C and a stirring speed of 10~20 r/min. (2) Turn on the metering pump and compressed air. (3) Observe whether the nozzle is spraying and whether the spray is even. (4) When stopping the use of the anti-caking agent, the metering pump and the feed valve should be turned off in sequence; after all remaining material in the pipes has been drained, compressed air should then be turned off. 2. Precautions: (1) The operation of the anti-caking agent coating station must be carried out by a dedicated person. (2) The pipeline between the metering pump and the nozzle should be insulated, and the nozzle should spray the material directly, with a distance of about 30 cm between the nozzle and the material. (3) The anti-caking agent should be added in the form of a spray using compressed air; it is not suitable to add it drop by drop. (4) Attention should be paid to adjusting and stabilizing the amount of anti-caking agent used. (5) A filter screen with a mesh size of around 60–80 should be installed between the discharge port of the anti-caking agent tank and the metering pump. VII. Packaging and Storage: Packaged in cardboard boxes or drums, with a net weight of 25 kg or 180 kg per unit; packaging can also be adjusted according to customer requirements ； Store in a cool, dry place indoors; shelf life is one year.
