Vertical Fertilizer Chain Crusher (Wannan Motor Driven)

Core Product Overview

The Gofine Vertical Fertilizer Chain Crusher is a single-rotor impact pulverizer engineered for crushing block-shaped compound fertilizers, high-moisture organic matter, and recycled off-spec granules in fertilizer production lines. Equipped with a top-mounted Wannan Motor and high-strength alloy steel chains, this machine delivers continuous, clog-free crushing with minimal maintenance.   

Why Choose Gofine’s Vertical Chain Crusher?

Authentic Wannan Motor Power: Features a vertically installed Wannan Motor directly aligned with the main shaft, ensuring high starting torque, low energy consumption, and stable operation under heavy block-crushing loads.   

Single-Rotor High-Speed Chain Impact: Inside the vertical crushing chamber, wear-resistant manganese steel chains rotate at high speed to shatter compacted fertilizer cakes into uniform fine powder.   

Non-Clogging Chamber for High-Moisture Materials: Unlike screen-type hammer mills that blind easily, the screenless vertical drop design and rubber-lined inner wall prevent damp organic matter from sticking.   

Compact Footprint & Easy Maintenance: Vertical rotor architecture saves workshop floor space, while a large access door allows operators to inspect or replace chains within minutes.

Working Principle & Structural Design

The Wannan Motor is vertically mounted at the top of the frame, driving the central rotor shaft passing straight through the crushing chamber. Multiple sets of wear-resistant steel chains are attached to the rotor. When bulk materials enter from the top feeder, high-velocity chain impacts instantaneously pulverize hard lumps before gravity discharges the fine powder through the bottom outlet.   

Primary Applications in Fertilizer Production

Compound & NPK Fertilizer Crushing: Breaks down hardened block-shaped raw materials (urea, MAP, DAP, potassium chloride) caused by storage humidity before batching and granulation.   

Recycled Material Pulverizing: Efficiently crushes oversized or undersized recycled granules screened out from rotary drum or disc granulation lines back into fine powder for re-granulation.   

High-Moisture Organic Matter Grinding: Processes fermented livestock manure, compost, peat, and humic acid with moderate moisture content without chamber clogging.   

Frequently Asked Questions

Q1: What materials is the vertical chain crusher best suited for?

A: It is specifically designed for crushing block-shaped materials in compound fertilizer production, recycled off-spec granules in granulation lines, and organic compost with moderate moisture content.

Q2: Why is a Wannan Motor used on this chain crusher?

A: Wannan Motors provide superior copper winding durability, high overload torque, and reliable continuous-duty performance, preventing motor overheating when crushing dense fertilizer lumps.

Q3: How does the vertical design prevent material clogging?

A: The machine has no bottom discharge screen, allowing crushed powder to fall freely by gravity. Combined with anti-stick rubber lining plates inside the cylinder, damp materials will not adhere to the chamber walls.
