The application scenarios of anti-spillage skirts highly overlap with the usage range of belt conveyors, primarily focusing on the field of bulk material transportation. Typical industries and scenarios include:
Mining and Metallurgy: Used for transporting ores after mining (such as coal, iron, and copper mines) and handling materials like sintered ore and steel slag in metallurgical plants, requiring resistance to high wear and high impact.

Typical Structural Composition of Wear-Resistant Anti-Spillage Skirts

Standard anti-spillage skirts are typically composed of a "main sealing layer + auxiliary accessories," with some complex scenarios incorporating multi-layer sealing structures:
Main Sealing Layer: The core functional component, made of rubber, polyurethane, or metal, designed as single-lip, double-lip, or multi-lip structures based on requirements (double-lip/multi-lip structures further enhance sealing effectiveness and reduce dust leakage).
Fixed Bracket / Clamping Plate: Used to secure the anti-spillage skirt to the steel structure on both sides of the chute, typically made of metal (such as steel plates or angle steel), requiring sufficient strength to withstand material impact.
Buffer / Adjustment Components: Some products are equipped with adjustment parts like springs or rubber pads, which can automatically compensate for wear of the anti-spillage skirt or adapt to dynamic deviations of the conveyor belt, maintaining long-term sealing effectiveness.
2. Common Installation Methods
The installation of anti-spillage skirts requires precise alignment with the conveyor chute to ensure proper fit. Common installation methods include:
Bolt Fixing: Connecting the fixed bracket of the anti-spillage skirt to the side plates of the chute via bolts, suitable for most scenarios, providing secure installation and ease of replacement and maintenance.
Snap-Fit Installation: Some lightweight anti-spillage skirts use snap-fit structures, eliminating the need for drilling, and can be quickly snapped into pre-set slots on the chute, ideal for small conveyors or temporary maintenance and replacement.
Multi-Layer Stacked Installation: For high-dust, high-leakage risk scenarios (such as coal washing plants or cement transportation), a multi-layer stacked structure of "main skirt + auxiliary skirt" is employed. The main skirt blocks large particles, while the auxiliary skirt seals dust, further enhancing anti-spill effectiveness.

The design of anti-spillage skirts revolves around three core objectives: "preventing leakage, reducing dust, and protecting equipment." Specific functions include:
Preventing Material Spillage
During belt conveyor operation, uneven loads or misalignment may cause material to spill from the edges. Anti-spillage skirts, through their elastic or rigid structure, closely adhere to both sides of the conveyor belt (or the inner side of the chute), forming a "barrier edge" that effectively prevents bulk material from leaking from the edges, reducing material waste and on-site cleanup efforts.
Suppressing Dust Dispersion
When dry bulk materials (such as coal or cement powder) rub against the conveyor belt and chute during transportation, they can generate significant dust. The tight fit of the anti-spillage skirt with the chute and conveyor belt reduces air circulation within the chute, minimizing dust escape, improving the working environment, and preventing dust from wearing down surrounding equipment (such as motors and bearings).
Protecting the Conveyor Belt and Equipment
Some anti-spillage skirts possess elasticity, cushioning the impact of materials on the edges of the conveyor belt and preventing sharp materials from directly scraping it, thereby extending the conveyor belt's service life. Additionally, their sealing function prevents material particles from entering transmission components like rollers and idlers, reducing equipment jams, wear-related failures, and maintenance costs.
Adapting to Dynamic Conveyor Belt Operation
High-quality anti-spillage skirts (especially those made of elastic materials) offer excellent flexibility and wear resistance, adapting to minor misalignments, vibrations, or deformations of the conveyor belt during operation. They maintain consistent contact with the conveyor belt, preventing seal failure due to dynamic changes.
