Fertilizer crusher for liquid fertilizer making

Can you provide me with the fertilizer crusher for NPK liquid fertilizer making

When you make liquid NPK fertilizer, the crushing step directly affects dissolution speed, clarity, and product stability. Common NPK raw materials such as urea, MAP, DAP, and potassium chloride need a uniform fine particle size before entering the dissolution tank. For them, you can choose hammer mills, chain crushers, or cage crushers according to hardness levels.

• 

  Hammer mill:

  A hammer mill works well for hard crystalline materials such as potassium chloride or MAP. Its fast-rotating hammers apply strong impact force and reduce crystals to small, uniform particles. This helps the crystals dissolve faster inside the heating or mixing tank and shortens the reaction time. The structure also supports continuous feeding, so factories that run large-scale NPK liquid fertilizer lines often choose this type of equipment.

  Chain crusher:

  This machine uses high-speed chains to strike and rub the materials until they reach the desired size. Its structure stays simple, stable, and easy to clean. Because it requires little maintenance and fits well into small or medium-capacity production lines. So it becomes a common choice when the formula includes salts that break more easily or do not need extremely fine particle size.

  Cage crusher:

  When you need very fine powder to prevent sedimentation in a high-purity water-soluble fertilizer, a cage crusher performs better. The material passes through two concentric cages, and the crushing force from both directions produces a highly uniform and fine powder. Many micronutrient formulas require this level of fineness because a smaller particle size improves solubility and reduces precipitation during storage. By combining high-speed rotation with an efficient airflow pattern, the cage crusher supports stable, clean, and low-noise operation.
