Stainless Steel Compound Fertilizer Crusher​ with Anticorrosion

Product Overview

The Stainless Steel Cage Crusher (also known as a Cage Mill) is a specialized horizontal impact crusher designed for the fertilizer industry. Unlike standard pulverizers, this machine is engineered to handle materials with higher moisture content and corrosive properties. Constructed from high-grade 304 or 316L stainless steel, it provides a contamination-free grinding solution for compound fertilizers, organic fertilizers, and chemical powders, ensuring a consistent fineness for downstream processing.

Product Features

• Superior Corrosion Resistance: The full stainless steel body prevents rust and chemical reactions, significantly extending the service life when processing acidic or alkaline fertilizers.

• Anti-Clogging Design: The internal cage structure and high-speed rotation prevent "pasting" or buildup, making it ideal for materials with up to 15% moisture content.

• Precision Impact Grinding: Utilizing the principle of counter-rotating cages, it delivers high impact energy to achieve uniform particle size without the need for internal screens.

• Easy Maintenance: The machine features a side-opening door design, allowing operators to inspect, clean, or replace the cages quickly, minimizing downtime.

• Stable Operation: Dynamically balanced rotors ensure low vibration and low noise, even during high-load continuous production.

Applications

This pulverizer is a versatile "workhorse" across several sectors:

1. Compound Fertilizer Production: Grinding urea, monoammonium phosphate (MAP), and potassium chloride.

2. Organic Fertilizer Processing: Refining composted materials and bio-organic pellets.

3. Chemical Industry: Processing highly corrosive chemical raw materials where carbon steel is unsuitable.

4. Bulk Material Crushing: Breaking down hardened or "caked" materials after long-term storage.

Working Process

The working principle is based on Relative Impact Crushing. The machine consists of two concentric cages (inner and outer) that rotate in opposite directions at high speeds.

1. Feeding: Material enters the center of the inner cage via the hopper.

2. Centrifugal Impact: The material is thrown outward by centrifugal force, striking the bars of the inner cage and then the counter-rotating bars of the outer cage.

3. Discharge: After multiple high-velocity collisions and shear forces, the pulverized powder falls through the bottom discharge port by gravity.
