Ultra Fine Fertilizer Pulverizer Air Classifier Mill 10-50 Micron Powder Mill
Ultra Fine Fertilizer Pulverizer Air Classifier Mill 10-50 Micron Powder Mill
The Ultra-Fine Fertilizer Pulverizer turns ordinary fertilizer into super-fine powder with a fineness of D97 10–50 μm — adjustable to your target particle size. Finer powder dissolves faster, absorbs more efficiently, and is perfectly suited for modern application methods such as fertigation, foliar spraying, and drone spraying.
1) Key Features
1. No screen, no clogging
Many grinders get blocked by sticky fertilizers. This machine uses air flow for classification instead of a screen, so it keeps running without stopping to clean — ideal for moisture-sensitive materials like urea.
2. Uniform powder every time
A built-in air classifier automatically sends coarse particles back for re-grinding. You get consistent fineness, batch after batch — meeting strict export standards.
3. Food-grade stainless steel contact parts
All parts that touch the fertilizer are made of 304 stainless steel. No rust, no contamination — safe for food-chain products.
4. Clean and dust-free operation
The enclosed system with a built-in dust collector keeps your workshop clean and recovers valuable fine material.
