Product Specifications

Technical details and manufacturing context for Metering Screw/Feeder

Definition
Within the Primer Feed System, the metering screw/feeder is responsible for accurately measuring and dispensing primer material from the storage hopper to the application point, ensuring precise and consistent material flow for coating or bonding processes.
Working Principle
A rotating screw, housed within a barrel or tube, conveys material from an inlet to an outlet. The rotation speed of the screw directly controls the feed rate, allowing for volumetric or gravimetric metering of powders, granules, or pastes.
Common Materials
Stainless Steel
Technical Parameters
  • Screw diameter, which determines the maximum volumetric capacity per revolution. (mm) Customizable
Components / BOM
  • Screw
    The rotating helical shaft that conveys and meters the material.
    Material: Stainless Steel
  • Barrel/Housing
    The stationary tube that contains the screw and guides the material flow.
    Material: Stainless Steel
  • Drive Unit
    Provides controlled rotational power to the screw, typically via a motor and gearbox.
    Material: Steel, Aluminum
Engineering Reasoning
0.1-100 kg/h with ±0.5% accuracy at 0.1-10 bar pressure differential
Screw deflection exceeding 0.1 mm at 50 N·m torque or material bridging at 45° angle of repose
Design Rationale: Hopper arching due to cohesive material properties exceeding yield strength (σ_y > 5 kPa) or screw fatigue from cyclic loading at >10^6 cycles with stress amplitude >150 MPa
Risk Mitigation (FMEA)
Trigger Electrostatic discharge (ESD) > 15 kV from polymer powder tribocharging
Mode: Controller PCB component dielectric breakdown
Strategy: Grounding system with <1 Ω resistance and Faraday cage shielding around electronics
Trigger Abrasive material with Mohs hardness > 7 (e.g., silica) at >50 kg/h feed rate
Mode: Screw flight wear exceeding 0.5 mm clearance, causing volumetric accuracy loss >3%
Strategy: Hardened tool steel (HRC 60+) screw with tungsten carbide coating (2000 HV) and sacrificial wear liners

Unsuitable: Highly abrasive materials without hardened/wear-resistant components (e.g., silica sand, metal powders)
Sizing Data Required
  • Required mass/volumetric flow rate (kg/hr or L/hr)
  • Material bulk density (kg/m³) and flow characteristics
  • Required accuracy/precision (±% of setpoint)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Screw wear and material degradation
Cause: Abrasive materials causing erosion of screw flights and housing, leading to reduced feeding accuracy and throughput.
Bearing failure and shaft misalignment
Cause: Overloading, improper lubrication, or contamination leading to bearing wear, increased vibration, and eventual shaft damage or seizure.
Maintenance Indicators
  • Irregular or fluctuating feed rate with audible grinding or scraping noises
  • Excessive vibration or overheating of the drive motor and housing
Engineering Tips
  • Implement regular inspection and cleaning schedules to prevent material buildup and ensure proper alignment of screw and housing components.
  • Use appropriate lubricants and monitor bearing conditions with vibration analysis to detect early signs of wear and prevent catastrophic failure.
