Used Vibrating Feeders: A Practical Guide

Introduction

Vibrating feeders are essential equipment in industries such as mining, aggregate processing, recycling, and food production, where controlled material feeding is required. Used vibrating feeders offer a cost-effective alternative to new units, providing reliable performance at a lower investment. This article explores the types, benefits, and key considerations when selecting used vibrating feeders, along with real-world applications and common FAQs.

Types of Used Vibrating Feeders

Vibrating feeders come in different designs, each suited for specific applications:

1. Electromagnetic Feeders – Ideal for precise, high-frequency feeding of fine materials.
2. Mechanical (Unbalanced Motor) Feeders – Robust and suitable for heavy-duty applications like mining.
3. Grizzly Feeders – Used for scalping and separating oversize material before crushing.
4. Syntron® Feeders – A well-known brand offering durable electromagnetic and mechanical options.

Comparison of Common Vibrating Feeder Types

Feature	Electromagnetic Feeders	Mechanical Feeders	Grizzly Feeders
Control	Highly precise	Moderate control	Less precise
Maintenance	Low maintenance	Higher maintenance	Moderate
Best for	Fine materials	Heavy-duty bulk	Scalping
Cost (Used)	$2,000 - $10,000	$3,000 - $15,000	$5,000 - $20,000

Benefits of Buying Used Vibrating Feeders

• Cost Savings – Used feeders typically cost 30-60% less than new units.
• Quick Availability – No lead time compared to custom-built new feeders.
• Proven Performance – Refurbished units from reputable suppliers ensure reliability.

Real-World Application: Recycling Plant Case Study

A scrap metal recycling facility in Ohio replaced its old conveyor system with a used Syntron® F-010 electromagnetic feeder to improve material flow into a shredder. The used feeder, purchased for $7,500 (vs. $18,000 new), provided:

• Consistent feed rate (20-30 TPH)
• Reduced jamming incidents
• ROI within 8 months

FAQs

1. What should I check before buying a used vibrating feeder?
Inspect the springs, motors, and deck condition. Ensure the unit powers on and vibrates smoothly.

2. Can used feeders handle abrasive materials?
Yes, but check for wear-resistant liners or replaceable wear plates.

3. How long do used vibrating feeders typically last?
With proper maintenance, 5-10+ years, depending on usage.

4. Are spare parts available for older models?
Many manufacturers (like Eriez, Syntron) still support legacy models.

5. Is retrofitting a used feeder possible?
Yes, motors and controllers can often be upgraded for better efficiency.

Conclusion

Used vibrating feeders provide an economical and practical solution for material handling needs. By selecting the right type and ensuring proper inspection, businesses can achieve significant savings without compromising performance. Reputable dealers and refurbishers can further enhance the lifespan and reliability of these units.
