Feeder

1. Introduction:

As the core component of material conveying systems, feeders deliver raw materials (such as ores, coal, and aggregates) to downstream equipment (like crushers and screens) in a continuous, uniform, and controlled manner. Classified by working principles into vibration-type, plate-type, chain-plate type, belt-type, etc., their selection directly impacts the efficiency and stability of the entire production line.

2. Main Applications:

Mining: Raw ore bins → jaw crushers, buffer bins → cone crushers, iron ore, copper ore (≤800mm lump) Sand and gravel aggregates: Stockpiles → primary crushers, screening machines → finished product bins, granite, limestone (0-300mm). Coal: Coal bins → washing equipment, loading station quantitative feeding, raw coal, cleaned coal (≤50mm). Cement: Limestone pre-homogenization stockpiles → vertical mills, clinker silos → cement mills, limestone (≤80mm), clinker particles. Recycled resources: Construction waste storage pits → crushing lines, scrap metal bins → sorting machines, concrete blocks, irregular scrap metal.

3. Core Features:

Vibration Feeder

(1) Dual eccentric shaft excitation: Self-synchronized vibration motor drives with adjustable amplitude (2-8mm), prevents clogging in handling moist materials.

(2) Grating pre-screening: Pre-installed stepped grating screens separate <50mm fine particles (reduces crusher load).

(3) Shock-absorbing spring: Rubber-steel composite spring with vibration transmission rate <5%, protects foundation structure.

(4) Wear-resistant liners: High-manganese steel base plates (thickness ≥15mm), service life>18 months (iron ore conditions).

4. Main Advantages:

(1) Low energy consumption (≤0.05 kWh/t per ton)

(2) Simple maintenance (no rotating parts)

(3) High adaptability (adjustable inclination angle 0-25°).
