🔧 Crusher Feeder Spring – Description

A Crusher Feeder Spring is a heavy-duty mechanical coil spring used in the feeder system of a crushing plant. Its primary function is to absorb vibrations and shocks generated by the movement of bulk material and the feeder mechanism, ensuring stable, efficient, and safe operation of the crusher.

📌 Purpose and Function

Vibration Damping: Absorbs dynamic forces caused by material loading and feeder vibration.

Load Buffering: Protects the structure and machinery from shock loads, especially during heavy material drops.

Support & Flexibility: Provides flexible yet stable support for the vibrating feeder tray or grizzly.

🧰 Typical Applications

Used in the support system of various types of feeders in crushing operations, such as:

Vibrating Grizzly Feeders (VGF)

Pan Feeders

Apron Feeders

Installed in primary crusher systems (e.g., jaw, cone, impact crushers) in:

Mining

Aggregate production

Quarrying

Mineral processing

Type : Heavy-duty compression coil spring

Material : High-strength alloy steel (e.g., 60Si2Mn, EN-45, EN-47) for durability and fatigue resistance

Design : Cylindrical or conical helical spring, depending on feeder type

Mounting : Typically mounted between the feeder frame and the crusher base/support structure

Finish : Anti-corrosion coated or painted for use in harsh industrial environments

✅ Advantages

Absorbs and reduces harmful vibrations

Protects structural components from fatigue and failure

Improves reliability and longevity of feeder and crusher

Enables smoother material flow into the crusher
