The key role of skirted baffles in material transportation: anti-spillage and guiding design

I. Spillage Prevention: Optimizing Efficiency and Cost

1. Physical Barrier Design

• Vertical Sidewalls: Flexible flanged skirts (height: 10–300 mm) made of PVC, PU, or rubber form enclosed channels with the belt, resisting material spillage caused by centrifugal force, vibration, or inclines.

2. Field-Tested Applications

• Grain Processing:
  • For wheat, corn, etc.: Skirt height ≥50 mm (accommodating granule size variations) + baffle spacing ≤150 mm → spillage rate <0.5%.
• Chemical Powders:
  • Seamlessly welded PU skirts paired with negative pressure suction systems prevent leaks of alumina, calcium carbonate, etc.
• Mining Operations:
  • Thickened rubber skirts (≥8 mm thickness) with embedded steel reinforcement withstand impact loads >200 kg/m&sup2;, reducing ore splatter losses.

II. Material Guiding: Precision Flow Control

1. Adjustable Guidance Mechanisms

• Angle Modulation:
  • Baffles and skirts with hinge/bolt adjustments (0°–45° inclination), e.g., 15° tilted baffles direct bulk goods to sorting ports.
• Zoned Layout:
  • Dense Baffles (spacing ≤100 mm) in front sections concentrate materials; gradual widening (up to 300 mm) in rear sections prevents compaction.

2. Specialized Baffle Designs

• Corrugated Baffles:
  • Minimize material buildup in sticky loads (wet coal, mineral slurries).
• V-Shaped Baffles:
  • Centralize materials in bidirectional systems via V-shaped openings, eliminating side spillage.
