Product Specifications

Technical details and manufacturing context for Vibrating Grizzly Feeder

Definition
A vibrating feeder component in concrete crushing machines that uses vibration and grizzly bars to separate fine material from the feed stream while uniformly feeding larger material to the primary crusher, improving crushing efficiency and protecting downstream equipment.
Working Principle
Uses an eccentric shaft or electromagnetic drive to create vibration, causing material to move forward along the deck while grizzly bars separate fines that fall through the gaps, with adjustable vibration frequency and amplitude to control feed rate.
Common Materials
High-strength steel, Abrasion-resistant steel plates, Rubber springs
Technical Parameters
  • Grizzly bar spacing determines maximum feed size and separation efficiency (mm) Customizable
Components / BOM
  • Vibrating Deck
    Carries and transports material through vibration
    Material: Abrasion-resistant steel
  • Grizzly Bars
    Separates fine material from coarse feed
    Material: High-carbon steel
  • Eccentric Shaft Assembly
    Generates vibration through eccentric rotation
    Material: Alloy steel
  • Spring Support System
    Isolates vibration from supporting structure
    Material: Rubber or steel springs
Engineering Reasoning
0.5-3.0 m/s vibration velocity, 15-25 mm amplitude, 700-1200 rpm frequency
Vibration velocity exceeding 3.5 m/s causes structural resonance, amplitude beyond 30 mm induces bearing fatigue failure, frequency below 600 rpm reduces material flow below 80% design capacity
Design Rationale: Resonance-induced structural fatigue at natural frequency harmonics (typically 2-3× operating frequency), bearing pitting failure from Hertzian contact stress exceeding 1800 MPa, spring steel fatigue from cyclic stress exceeding 350 MPa yield strength
Risk Mitigation (FMEA)
Trigger Unbalanced rotating mass causing 0.2 mm eccentricity
Mode: Excessive lateral vibration exceeding 4.0 m/s velocity
Strategy: Dynamic balancing to ISO 1940 G6.3 standard with residual unbalance < 1 g·mm/kg
Trigger Grizzly bar abrasion wear reducing cross-section below 60% original
Mode: Material bridging and flow reduction below 50% design capacity
Strategy: Hardfacing with 58-62 HRC tungsten carbide overlay on bar surfaces
