1. What is Vertical Crusher (Self-Cleaning Crusher)?

A Vertical Crusher (FQ Series), also known as a self-cleaning vertical chain crusher, is a high-efficiency crushing machine engineered around a heavy-duty vertical shaft structure. By utilizing high-speed rotating chain links or beaters to strike incoming raw materials, it achieves fine particle reduction. Its unique inner liner and vertical pass-through design prevent sticky or high-moisture materials from clogging, making it widely used in fertilizer, mining, chemical, and building material industries.

2. How does Vertical Crusher work?

Raw materials are fed vertically into the top inlet of the crushing chamber. Driven by an electric motor (7.5 kW to 45 kW) operating at a high speed of 1470 r/min, the central vertical shaft drives high-strength chains or hammers to rotate at high velocity.

As material drops through the chamber, it is repeatedly struck, sheared, and shattered by the rotating beaters and impacted against the heavy-duty lining plate. The crushed fine particles are immediately discharged from the open bottom without screen grates, eliminating material build-up and ensuring a continuous throughput ranging from 2–4 t/h up to 10–20 t/h.

3. Advantages of Vertical Crusher

• Self-Cleaning & Anti-Clogging: Designed without bottom screen bars, enabling smooth processing of high-moisture organic wastes (chicken manure, sludge, compost) without sticking or blockages.
• Uniform Fine Crushing: Operates at a constant speed of 1470 r/min, delivering consistent, fine particle sizes ideal for granulation processes.
• High Processing Throughput: Heavy-duty models (FQ1000) handle up to 10–20 t/h, meeting the demands of large-scale industrial fertilizer production lines.
• Compact Footprint & Low Maintenance: Vertical layout minimizes floor space requirements (from 650×920×820 mm to 1200×1700×1450 mm), with wear-resistant chain heads for extended operational lifespan.

4. Application of Vertical Crusher

• Organic & Compound Fertilizer Production: Fine crushing of high-moisture fermented manure, composted sludge, urea, and raw minerals prior to granulation.
• Livestock Waste Recycling: Fine particle processing of cow, swine, and poultry manure compost.
• Chemical & Building Materials: Crushing medium-hard materials such as compound fertilizers, glass, clay, and shale.
• Municipal Waste Treatment: Size reduction of organic solid waste and bio-sludge.
