Technical details and manufacturing context for Discharge Feeder

Definition
The Discharge Feeder is a critical component of the RAP Storage Bin system, responsible for precisely controlling the flow rate and discharge of reclaimed asphalt pavement (RAP) material from the storage bin to downstream processing equipment, such as mixers or conveyors, ensuring consistent and controlled material supply.
Working Principle
Typically operates using a rotating screw (auger), vibrating tray, or belt mechanism. It is activated to draw material from the bin's hopper section. The speed or amplitude of the mechanism is controlled to regulate the discharge flow rate, providing a steady, metered supply of RAP material to the asphalt plant's mixing process.
Common Materials
Carbon Steel, Abrasion-Resistant Steel Plate
Technical Parameters
  • Maximum discharge capacity or flow rate. (t/h) Per Request
Components / BOM
  • Feeder Screw (Auger)
    Rotates to convey and meter the discharge of material.
    Material: Abrasion-Resistant Steel
  • Drive Unit
    Provides controlled rotational power to the feeder mechanism.
    Material: Cast Iron / Steel Housing
  • Inlet Flange
    Sealed connection point to the storage bin hopper.
    Material: Carbon Steel
Engineering Reasoning
0.5-3.0 m³/min material flow rate, 0.1-0.8 MPa discharge pressure
Material flow rate exceeds 3.5 m³/min causing structural deformation, or discharge pressure surpasses 1.2 MPa leading to seal rupture
Design Rationale: Excessive shear stress from material flow exceeding τ_max = 45 MPa (based on ASTM A36 steel yield strength), combined with pressure-induced hoop stress σ_θ = (p·r)/t exceeding material fatigue limit at 10⁷ cycles
Risk Mitigation (FMEA)
Trigger Material bridging due to cohesive arch formation with internal friction angle φ > 60°
Mode: Flow obstruction causing feeder motor overload at >150% rated torque
Strategy: Install pneumatic vibrators with 0.6 MPa air pressure and 50 Hz frequency to disrupt arch formation
Trigger Abrasive wear from silica content >15% in conveyed material
Mode: Feeder blade thickness reduction below 2 mm minimum specification
Strategy: Apply tungsten carbide hardfacing with 65 HRC hardness and 0.8 mm overlay thickness
