Rotary drum fertilizer granulator is one of the essential granulating equipment that can manufacture mineral materials into specific shapes. The drum fertilizer granulator is one of the key equipment in the compound fertilizer industry and is suitable for cold and hot granulation as well as the large-scale production of high, medium and low concentration compound fertilizers. The main working method is pellet wet granulation. Through a certain amount of water or steam, the basic fertilizer is fully chemically reacted after the humidity is adjusted in the cylinder. Under certain liquid phase conditions, with the help of the rotation of the cylinder, the material particles are The extrusion force is generated to form a ball.

4 Kinds of Raw Materials with High Potassium Fertilizer Efficiency

Primarily, the raw materials for the production of granular potash fertilizer were originally from potassium salt, carnallite and bitterstone. However, due to the difficulty, long cycle and high cost of mining, we recommend that manufacturers who want to produce K-fertilizer pellets can buy by-products or powders, etc., containing potassium element. Also, you can use potassium granulator to make particles from all kinds of powders in many industries.

There are many types of K-fertilizer. For example, potassium chloride, potassium sulfate, potassium dihydrogen phosphate, potassium magnesium sulfate, potassium stone salt, potassium magnesium salt, carnallite, potassium nitrate, kiln ash potassium fertilizer, etc. Furthermore, KCL leads due to its high nutrient concentration among these potash-containing materials. Many fertilizer factories prefer it because of its abundant resources and relatively low cost. Thus, it plays a dominant role in agricultural production, accounting for over 90% of potassium fertilizer usage.

Generally speaking, some experts have proven that the use of these 4 raw materials with high potassium content produces the best K fertilizer. Typically, expects convert potash fertilizer into statistics in the form of K2O to evaluate actual fertilizer efficiency. For instance, 1 ton of KCL equals 0.631 tons of K2O; 1 ton of K2SO4 converts to 0.595 tons of K2O; 1 ton of KNO3 equals 0.47 tons of K2O; 1 ton of KH2PO4 converts to 0.34 tons of K2O. Also, the potassium fertilizer granulator serves multiple functions, including the production of Russia Red Potassium and NPK compound fertilizers. Additionally, it granulates NH4Cl, MAP, DAP, (NH4)2SO4 and NH4HCO3.

Other Powder Materials Granulation by K Fertilizer Pelletizer for Different Usage

Ore Powder

Ore Powder

Firstly, powder materials such as antioxidants, bleaching powder, zinc oxide, heavy calcium, light calcium, fluorite, phosphate rock powder, metal powders, fillers, calcium silicate, white carbon black, rubber and plastic additives, undergo granulation for industrial use. Besides, industries require these granules for manufacturing processes that demand precision, efficiency, and safety. For instance, granular zinc oxide serves as critical components in the production of high-quality rubber and paint. Similarly, metal powders, after granulation, find application in powder metallurgy for producing complex shapes with high precision.

In agriculture, K-fertilizer granulator can make pellets from substances like potassium carbonate, calcium chloride, dicalcium phosphate, and feed additives. Moreover, this machine ensures nutrient uniform distribution when these materials serve as soil amendments, fertilizers, or feed additives, leading to improved crop yield and animal health. For example, granular dicalcium phosphate acts as an excellent source of nutrition for livestock, while potassium carbonate granules are be of use to condition soil and correct potassium deficiencies, promoting plant growth.

Granulating powder materials such as steelmaking additives, snow-melting agent, and environmental materials transforms them into more useful forms for environmental management applications. For instance, granular snow-melting agents facilitate snow-cleaning easier on roads and walkways during winter. In addition, environmental materials, including specific types of clay and absorbents, when granulated, are be of application for controlling spills and managing waste, aiding in the containment and cleanup of hazardous materials.
