Material Pretreatment: Key to Conveyor Efficiency

Better Pretreatment, Higher Conveyor Efficiency
In industrial logistics systems, conveyors serve as core equipment for material transportation, with operational efficiency directly impacting overall production capacity and costs.
Many enterprises prioritize conveyor equipment upgrades and transmission system optimizations while overlooking a critical prerequisite: material pretreatment. In fact, unprocessed material properties are the primary cause of conveyor blockages, belt wear, and excessive energy consumption. Effective pretreatment is essential to maximizing conveyor efficiency.
What is Material Pretreatment?
Material pretreatment refers to the targeted physical or chemical processes applied to materials prior to entering the conveyor system. Its purpose is to optimize material characteristics—including shape, moisture content, particle size, and cleanliness—to ensure full compatibility with conveyor operational requirements.
This process is particularly critical in industries such as mining, building materials, chemical engineering, and grain processing, where varying material properties highlight the need for customized pretreatment solutions:
Mining sector: Raw ore from blasting typically contains oversized rock fragments (over 50cm in diameter), cohesive soil, and free moisture. Direct conveyance may cause blockages, belt misalignment, slippage, and increased motor load.
Chemial industry: Agglomerated powder materials require crushing to prevent bridging and blockages in conveying pipelines, which can disrupt production continuity.
Three Core Dimensions of Material Pretreatment
- Particle Size Control: As a fundamental step, crushing equipment (e.g., jaw crushers, impact crushers) reduces oversized materials, followed by screening to ensure uniform particle size within the conveyor's design limits. For instance, crushing ore larger than 30cm to below 10cm can improve conveying efficiency by over 20% and reduce localized belt wear.
- Moisture Regulation: For cohesive materials like fly ash and slag, moisture control (8%-12% ideal range) is achieved through rotary dryers or anti-adhesive additives. This minimizes material adhesion and accumulation on belts, chutes, and hoppers, reducing cleaning frequency from 2-3 times weekly to once monthly.
- Impurity Removal: Magnetic separators remove ferrous contaminants (e.g., metal chunks, steel bars), while air separators eliminate light impurities (e.g., wood chips, plastic film). This prevents belt damage and protects conveyor components such as rollers and bearings.
Practical Application Case
A large building materials enterprise previously faced challenges with wet fly ash conveyance: direct transportation caused severe belt adhesion, requiring 2 shutdowns weekly (2-3 hours each) for cleaning. Annual additional maintenance costs exceeded hundreds of thousands of yuan, with nearly 10% production capacity loss.
After implementing an integrated pretreatment system (drying, screening, magnetic separation), material moisture was reduced from 25% to 10%, particle size controlled below 5mm, and impurity removal rate reached 98%. Post-upgrade results included: 80% reduction in downtime, 2.5x extension of belt service life (from 1 year to 2.5 years), 15% lower energy consumption per unit material, and full recovery of equipment investment within 6 months.
