Technical details and manufacturing context for Bucket

Definition
The bucket is the primary load-bearing component of an elevator bucket conveyor system, responsible for scooping, containing, and discharging bulk materials such as grains, powders, granules, or small parts during vertical or inclined transportation. It is securely attached to the conveyor's belt or chain and moves in a continuous loop to transfer materials between different process levels.
Working Principle
The bucket is attached to a moving belt or chain. As it passes through the loading point (boot or feed chute), material is scooped or fed into it. The bucket then carries the material upward along the conveyor's path. At the discharge point (head pulley or sprocket), the bucket inverts or passes over the pulley, allowing gravity to empty its contents into a chute or receiving hopper, completing the material transfer cycle.
Common Materials
Carbon Steel, Stainless Steel, Polyethylene (PE), Polypropylene (PP), Nylon
Technical Parameters
  • The primary dimensions defining bucket size and capacity, typically including front width, projection (depth), and height. (mm) Per Request
Components / BOM
  • Front Lip
    The leading edge that scoops material during loading and aids in clean discharge.
    Material: steel or polymer
  • Back Plate
    The structural rear surface where mounting hardware attaches the bucket to the conveyor belt or chain.
    Material: steel
  • Side Walls
    Contain the material within the bucket during transport and provide structural rigidity.
    Material: steel or polymer
  • Bottom
    Forms the base of the bucket that supports the material load.
    Material: steel or polymer
Engineering Reasoning
0-150 kg load capacity, 0-3 m/s vertical velocity, -20°C to 80°C ambient temperature
Material yield strength exceeded at 250 MPa stress, fatigue failure at 10^6 cycles at 150 MPa alternating stress, wear limit at 5 mm material loss
Design Rationale: High-cycle fatigue from cyclic loading at material grain boundaries, abrasive wear from particle friction (coefficient μ=0.3-0.7), stress concentration at fillet radii below 5 mm
Risk Mitigation (FMEA)
Trigger Material embrittlement from cold working exceeding 30% reduction
Mode: Brittle fracture at stress risers during impact loading
Strategy: Normalization heat treatment at 900°C followed by controlled cooling at 50°C/hour
Trigger Corrosive pitting from chloride ion concentration exceeding 500 ppm
Mode: Stress corrosion cracking initiating at pit depth >0.1 mm
Strategy: 316L stainless steel construction with 3% molybdenum content for chloride resistance

Application Fit & Sizing Matrix

Operational Limits
pressure: Atmospheric to 0.5 bar (static head dependent)
flow rate: 5-500 m³/h (capacity dependent)
temperature: -40°C to 120°C (varies with material)
slurry concentration: Up to 70% solids by weight (material dependent)
Media Compatibility
✓ Dry granular materials (grains, seeds, pellets) ✓ Free-flowing powders (cement, flour, chemicals) ✓ Small aggregate materials (sand, gravel, plastic granules)
Unsuitable: Highly viscous or sticky materials (wet clay, tar, adhesives)
Sizing Data Required
  • Material bulk density (kg/m³)
  • Required throughput capacity (tons/hour)
  • Conveyor speed and bucket spacing (m/s and m)

Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Abrasive wear
Cause: Contact with abrasive materials (sand, gravel, minerals) causing gradual material loss, especially at cutting edges and bottom surfaces
Fatigue cracking
Cause: Cyclic loading from repeated digging/loading cycles leading to stress concentration at weld joints, corners, and attachment points
Maintenance Indicators
  • Visible cracks or significant deformation in bucket structure or cutting edges
  • Excessive material loss (more than 30% thickness reduction) at critical wear points
Engineering Tips
  • Implement regular wear plate inspection and replacement program before critical thickness limits are reached
  • Apply proper welding procedures and post-weld heat treatment when repairing or modifying bucket structure to maintain material properties

Compliance & Manufacturing Standards

Reference Standards
ISO 9001:2015 - Quality management systems ANSI/ASME B30.9 - Slings DIN 6615 - Buckets for building machinery
Manufacturing Precision
  • Wall thickness: +/-0.5mm
  • Handle attachment weld strength: +/-10% of specified load rating
Quality Inspection
  • Visual inspection for surface defects and weld integrity
  • Load testing to verify structural capacity and safety factor

Frequently Asked Questions

What materials are best for corrosive material handling in elevator buckets?

Stainless steel offers excellent corrosion resistance for harsh materials, while polyethylene (PE) and polypropylene (PP) provide chemical resistance at lower cost for less abrasive applications.

How do I select the right elevator bucket for my conveyor system?

Consider material characteristics (abrasiveness, moisture, temperature), capacity requirements, discharge method, and whether vertical or incline transport is needed. Our engineers can help match bucket design to your specific application.

What maintenance is required for elevator bucket conveyor components?

Regular inspection for wear on the front lip and bottom, checking fastener integrity, and monitoring for material buildup. Carbon steel buckets may require periodic coating maintenance, while polymer buckets resist corrosion but need inspection for cracking.

Can I contact factories directly on CNFX?

CNFX is an open directory, not a transaction platform. Each factory profile provides direct contact information and production details to help you initiate direct inquiries with Chinese suppliers.
